How to build a cement rozchin for pouring pidlogs. Concrete screed for underlayment coating: color and recommendations.

⁰

Do you need a concrete screed?

The screed is the basis of the pіd pіdlogi for pіdlogi, yak vygotovlyayut z concrete. The won is recognized for:
• folding even surfaces;
• vikonannya roles of the basis with the method of vanity, which are equally divided;
• security of health.

Tie type:

• pov'yazana (sumish is poured on a broken primer base that shows serious vanity);
• on a split ball (the visibility between it and the basis of waterproofing) - there are three times less and may not be less than 3 cm;
• with an insulating ball (zastosovuєtsya, for example, for podlogi z pіdіgrivom);
• armored (the most popular, secure promotion of the city);
• with fiber optic fiber (reinforcing reinforcement is added and the sum of plastic is added, because of which there is more resistance to cracks, and it is cheaper).

Cooking a meal

Concrete screed - a warehouse of a rare type, the materials for which can be porous concrete, cement + sand, which are ready to be summed up. Materials are selected in the fallow type according to the type of overbrushed coating. As soon as the underlay is done first, or a major overhaul is carried out, a new screed is needed in the cement-food warehouse (if the work is done independently by hand) or porous concrete. During cosmetic repairs and simple replacement of the coating, it is only necessary to repair the surface, zastosovuchi for concrete screed self-verifying sumish. You can come to our factory with delivery.

What brand of concrete for screed is better than bathing? There is no such thing that a specific type is needed, but the brand is not less expensive, like a screed, but the proportions of cement and sand for preparation. We recommend winning at least class B7.5. For clarity, the table below

Brand		Proportion
difference	cement	Proportion
300	600	3:1
200	600	4:1
300	500	2:1
200	500	3:1
300	400	1:1
200	400	2:1
150	400	3:1
200	300	1:1
150	300	2:1
100	300	3:1

In apartments, it is more important to win the price of 200 chi 150.

Vitrata concrete on the screed?

For a rozrahunka it is necessary to know:

accommodation area;
tovshchina (visoti) screeds;
the proportion of warehouses for the sum;
spіvvіdnoshnja loneliness masi that vyagu warehousing.

For example, at a place of 20 sq.m, it is necessary to pour a screed of 5 cm. In most cases, the ratio of tables is 1:3. So, it is necessary to use 0.75 cubic meters (1x3/4) for 1 cubic meter and 0.25 cubic meters for cement.

Spivvіdnoshnja zahodіv

Material	K-t kg in 10 l	K-t kg in 1 m3
Pisok	14-16	1400-1600
Crushed stone/zhvir	15-17	1500-1700
Cement	13-14	1300-1400

At 0.25 cubic meters of cement per kg of yoga, an average of 337.5 kg (0.25x1350) is required. Pisku - 1125 kg (0.75 x1500).

Get respect! Ready to sum up at the process of settling and go out less obligated for the rahunok, filled with empty particles of zapovnyuvach. To that, 1 cube of dry sumishi is given to the average 0.6-0.7 cubes of finished mass. That dry material needs to be bathed more.

How to build a screed

prepare the base, clearing the sight of smittya;
put a mark "0" equal;
designate the screed company (in terms of the main wall, in the base to the threshold, choose the company of the sublogs (tiles, laminate, linoleum + glue ball);

Screed, cement or concrete, often victorious for vashtuvannya pіdlogi. Might be self-supporting cover for pidlog. For example, at non-living premises, garages, warehouses, workshops. At the dwelling there is a vikoristovuetsya as a basis for laying a load-bearing surface underlay, linoleum, parquet is too thin.

What is needed for preparing a meal

For whom we need cement, sand, water. To improve plasticity and plasticity, plasticizers can be added. But in domestic minds, it is best to do without them.

Plasticizers for concrete are subdivided into 4 groups;

Before the concrete difference of the cream of the appointed components, it is necessary to enter the second step. You can use crushed stone, marmur krichta, expanded clay. Concrete cuts for the preparation of pidlog for living quarters are practically not beaten. That’s why the language was given more or less about food and cement trade.

Cement

The basis of rozchinu is cement. The very wines are given to the underlings of mysticism and quality. When choosing cement, follow the brand to respect. Cement is denoted by the letter M and numbers. The numbers in this way point to those that are the focus of the building material. For example, brand M50. Tse means that the cement of the brand of vitrimuє is not more than 50 kilograms per unit area or obligatory. To that, first choose the components and the difference, it is necessary to appoint, as if you would be interested in your application.

vidi cement

Proportions of the difference

The most optimal, vivirenim fates are important, if one piece of cement falls into three pieces of sand. Water at the same time is stained with spivvіdnoshnі: two parts of the water for one cement.

There may be other options. For example, 1 part of cement up to 1 part of sand, or 1 to 2. But, even if such proportions allow you to improve the quality of the soil, you need to use fineness. Rozchin shvidko skoplyuetsya, yogo importantly virіvnyat. It is necessary to remember that zbіlshennya vmіstu pіsku in rozchinі either lead, or else at the same time, leading to a change in the quality of that mіtsnosti.

For the preparation of a screed screed, call for cement not lower than M300.

Rozchin can be prepared by yourself or you can buy ready-made dry sumish in the store. It is recommended that you buy sumish with a brand no lower, lower than M200. Ale vrahuyte, sho in a dry sumish it is shown that the value is not cement, but the rose itself.

Zrazkovy rozrahunok kіlkostі nebkhіdnih materialiv

When rozrahunku it appears from the following parameters:

area of application - 40 sq. m;
screed, buvaє 2 cm or 5. Take 5 cm;
standard rozchin, that is one part of cement for 3 parts of sand.

Nasampered, we can calculate the cubic capacity of the possible screed. For that 40 sq. m multiplied by 0.05 m. We take 2 cubic meters. meter difference. Pіdrahuєmo, we need some cement. Vin to become one piece at the retailer, that is half a cube. meter. In one cubic meter there is 1300 kilograms of cement. It is important that we need 650 kilograms. So you can puff yourself up, skilki will be needed for a dog and water.

Gotuemo rozchin

On the other hand, one thing is respected. It is necessary to work in such a quantity that you can work in one hour. Otherwise, it seems, if you have a year, then it is necessary to change the time for the year of work.

Let's continue. A note about the preparation of roses from dry sumish. We need a container for this breeding, a perforator with a nozzle. You don’t take the rozmіshuvat manually, you don’t take away the quality of the necessary vibe in any way.

Next steps:

visipaemo dry sumish at єmnіst;
relatively peremishuєmo її for an additional perforator;
yakscho it is planned to increase the number of rozchins for additional additives, a little bit of rozchinny at the water. Yakshcho nі, we add water to the bag in a sum, we constantly mix it up. The results in us can have a uniform mass, similar to thick sour cream;
zalishimo rozchin hvilin for five;
Let's get to work.

At the vapadku, if the rozchins are prepared from the okremy components, we fix it with the coming rank:

Before the cob, it is necessary to clean the place of pouring from the smitta thinly. Let's do it:

Rozchin for screed pіdlogi, at first glance, it's easy. For the truth, the very proportions may be of the highest importance for robots. With the wrong mix of materials, further work can turn into a waste of energy, an hour and a penny. Therefore, in everyday life, the screed of the pidlogs is taken into account by the most advanced stage, at which the yak_st is added to the yak_st of the future pidlogs.

In this hour, the range of coatings for the application is teeming with diversity: putty, tile, plaster, etc. However, it is impossible to find out about their value and obsyag added to the cement, buying in the finished look. In addition, there are different chemical additives that increase the quality of materials. І tse new main role is given to cement. It should be noted that in the process of preparation at the plant, the same amount of cement is added, the stench is not saved on it, and the amount that is indicated, as a rule, is factual.

The range of dry budіvelny sumіs for screed majestic and may drink on the market.

Mitsnist screed

Basically, on the packages of warehouses, it is indicated that the pressure on the compression becomes 10 MPa. For concrete, the M150 grade is the closest to the first indicator, for which MPA is 12.8.

Keep in mind what people should take when proportions are folded ideal mind, then. pіsok, what to revenge minimum quantity clay. It is necessary to remember about it, because when the clay is prepared, it will envelop the food, thereby changing the chip itself, after which the minerality decreases. That's why it's important to give specific numbers. At different times, the amount of cement in retail increases by 20 cm and the quantity of radin changes.

It should be taken into account that the durability of concrete coatings, as well as its density, should not be deposited in such a way in terms of vicorous materials, as in the correctness of all proportions. So, you can solve problems from sound, heat, water insulation, and communication systems.

Sumish cement and pisk.

TsPS - tse sumishi cement that pіsku, scho often vikoristovuyutsya for screed pіdlog. It is easy to prepare independently, however, for whom it is necessary to know all the proportions of cement and sand for the preparation of screeds. Indicate that those who, in similar proportions of figures, lie in the main type of planned advancement on the sub-log, which is more, more cement is added to the retail (especially it is worth reaching the great stores and industrial applications).

On proportions, such factors are also added, like virіvnyuvannya surfіnі, planuvannya pіdnyattya surіvіnі pіdlії, nebhіdnіnіnіnіnіnіnі іrіnіh pipingіv і komіnіkatііnіkh systems і rozpodіl navantazhennia na svіvnyuvannya svіvnyuvannya і thermal іlоtії.

Proportions of cement to sand for screed

Nasampered, the proportions for the screed should be deposited according to the grade of cement.

Table of proportions for DSP.

It is necessary to respect, for the screed and the brand name, the brand is guilty but not lower than M150, most often it is M200.

Rozrahunok screeds for pidlog

To finish it often before carrying out repairs, it is necessary to rebuild the balance necessary material, Cost and tie-downs.

Rozrakhovuvati rozchin for screed pіdlogi can be so.

We are going to secure the necessary obligations of future materials. For whom the community of the future screed is multiplied by the area covered.

For example, at 40 sq.m. and a ball of tovshchina 5 centimeters. In times it is necessary 40 * 0.05 = 2 cubic meters.

If so, the amount of cement and sand is being boosted. Mixing the difference is in the proportion of 1 to 3, it also requires 0.5 cubic meters of cement and 1.5 cubic meters of sand. The volume of a cubic meter of cement should be approximately 1,300 kilograms; to purchase close to 650 kilograms of cement (0.5 * 1.3). So, you can carry out a rozrahunok proportions of that particular area. Zavdyaki such a rosework can be provided in advance with the necessary supplies of budmaterials.

Dotrimannya optimal proportions - constipation yakіsnoї roboti and as a legacy of the long service of the screed.

It is worth noting that when preparing a concrete mix, it may not be possible to receive special features - step by step, the volume will increase. To this, it’s simple to explain: zapovnyuvach, at the warehouse of some є drіbnі particles, penetrating into the empty concrete gap, filling them and changing them themselves. That is why, when 1 cubic meter of dry sum is planted, with good layouts, no more than 0.7 cubic meters of finished rozchin comes out. Therefore, for the preparation of 1 cubic meter, it is necessary to take three more dry speeches from the reserve.

Mixing components in retail

Dry and rare components vary widely in different containers. Rozchin for pouring sublogs are prepared according to the proportion to the appointed order. Nasampered, dry components are mixed, tobto fiber, sand and cement. Cement M400 is mixed with piskom at spivvіdnennі 1 to 3, for example, 16.7 kg of cement is required for 50 kilograms of sand. The mixing of dry elements is done with a stretch of 5 strands.

At another container, the plasticizer is mixed with water. For 50 kg of cement, about 190 g of plasticizer is needed. The required volume of water is 1/3 part of the mass of cement, so 1/3 part of the bear needs 5.6 liters of water (looking at those that use the plasticizer for 0.6 liters). Sweat, some dry elements are churning, and then we’re gradually suffocating dry summation from the water, when we’re good at it.

For mixing sumish without breasts, it’s better to vicorate a budding mixer.

When pouring water into dry sumish, breasts may appear, which are important to stir.

I will mix the rozchin manually for a long time and it is important that it is recommended to use a daily mixer or a drill with a nozzle. Power tools allow you to perform the procedure even more.

So, the screed of the base is ready, and for the correct proportions of cement and sand, you can take the necessary size. The next mother on the uvaz, which works with a viscous rose is significantly more foldable, but there will be fewer cracks on the surface.

To hide the cracks in the hanging, it is necessary to wet the surface of the day.

Recognize

Є great zapovnyuvach, vikoristovuvaniya is more important in the process of virobnitstv important concrete (crushed stone, gravel thin.). Also, it is a drіbniy zapovnyuvach, which zastosovuєtsya less when preparing excellent concrete. Surely, everyone knows that during everyday life, the sand may stagnate, and the process of preparing a concrete rozchin is not like a wine. The sand is called a dribbling zapovnyuvach, to that yogo pishchinki can finish miniature roses. Ale and pisok become great, middle and dry.

Sand for retailing is a necessary component and wines are reviewed for rozmirom. Photo for por_vnyannya rozmіru pіshchinok.

Screed pіdlogi: scho better - concrete chi tsps?

Before the cob of cob, screeds are screeded by a lot of people sticking to food about those that concrete is more beautiful or cement-food sumishi? Practice shows that for a thin screed it is necessary to mix the sum of the cement and sand, and for the tovstoy (more than 4 cm) it is recommended to seal the traditional concrete, which does not give cracks.

It is necessary to know one more thing. When mixing concrete with expanded clay, a heat insulator will come out, and when crushed with crushed stone, it will remove the cover to show the greatness of the advancement (crushed stone can be miraculously sealed with cement).

In addition, the concrete is vibrated when the bud sum is poured onto the ground, for the removal of a monolithic base or a decorative coating.

Varto add that, for the presence of a minimum set of tools (milk capacity, shovel, shovel, bucket), that calculator can be independently carried out with the correct proportions. And for the given proportions to concrete or cement or other components, you can independently prepare some sum for screeding. Krym tsgogo, for the sake of the all-world's measure, you can find anonymous graphs, tables, electronic calculators and other brown materials about portioning.

fill cement screed– tse duzhe vіdpovіdalny process pіd hour vikonannya weekly work. Ale zgіdno with a bagatarіchny dosvіdom, during the victorious operation of such an operation, a large number of bluffs are allowed. Most of the pardons are due to a properly prepared rose. In order to take away the mіtsnu and the yakіsnu basis, it is necessary not only to choose the yakіsny cement, the ale and the nobility, in some proportions, rozchins are prepared. Only then you can recognize the difference between the ideal consistency and miraculous quality.

When vikonannі obobki often can be used such a rule, like talking about those that the skin of the offensive ball is to blame for the mother, and the same indicators of mentality, that and the front. Ale, as a testament to practice, it strengthens more in the future. For radian hours, no one understands about such a thing.

Today is calm, there is a wide opportunity to choose a different option tax cover. You can add tiles, putty, plaster. Such a range of products often calls out impersonal folding, even if people do not know which of the products produced by the wart will work for their minds of exploitation.

Mixing process

When mixing components, it is necessary to prepare containers, in which case it is necessary to roztashuvat okremo dry and sparse warehouses. Dalі varto dotrimuvatsya offensive instructions:

Take all the dry ingredients and the last ones from the container. Cement, sand and fiber are brought to dry warehouses. Take cement M400, add to a new squeak at a 1:3 ratio. If you look at the butt, then for 50 kg of pist you will need to stock up on 16.7 kg of cement. The process of mixing dry ingredients can be carried out with a stretch of 5 quills.
Take another container and add a plasticizer with water to it. If you have 50 kg of cement, then you need a plasticizer 190 7. Water is added in a quantity of 1/3 of the mass of the binder component. In other words, 5.6 liters of water fall on 50 kg of cement. At tsimu 0.6 l water pіde pіde razvedennâ plasticizer.
Now you can proceed to the mixing of dry and regular warehouses. Here it is necessary to take a container from a dry bag and to steam it properly in another capacity. With whom, postiyno pomishuvati. When you add it in dry sumish, take it out with breasts, as if sweating, it will be easy to suck it up.

Razmishuvati manually even more importantly and for a long time. For whom it is necessary to vicorate a daily mixer or a drill with a nozzle. Zavdyaks in the process of provoking the power tool are working on this manipulation as well.

For whom the process of preparing sumishi is over. I would like to say a few words about the sum of the omitted rozchin. Vaughn is not guilty of buti over that thick, to that with a viscous warehouse, it’s already important to work out. Ale and rare wines are also not guilty, otherwise cracks on the surface of the screed will not disappear.

Yakі proprtsії cement rozsіn for screed pіdlogi describ

If you want to close the cracks at the moment of hanging the screed, it is necessary to repair the surface for additional water.

Vitrata rozchinu

Know the cob required quantity to the material. For whom it is necessary to take the area of the screed multiplied by the tovshchina of the possible construction. For example, with a footprint area of 40m2 and a torso ball - 5 cm, the size of the difference is 40x0.05 = 2 m3.
If so, you can vikonate the rozrahunok of the necessary amount of sand and cement. For the preparation of vicariously, such a proportion is 1: 3, it will be necessary to use 1.5 m3 of sand and 0.5 m3 of cement. In one m3 there is 1300 kg of cement, which will require 0.5 x1, 3 = 650 kg.

From otrimanih data, you can add stained glass, stained glass screed of a specific area. Such a rozrahunok is allowed to be prepared for a long time to prepare the need for a large amount of budmaterial.

How does the masonry work on the vape floor

On the video - spіvvіdnoshennia to cement and pіsk for screed pіdlogi:

You can read about the characteristics of the cement-vapour coating in Denmark

It is not easy to fit the screed of the logs, as all components are prepared correctly, as well as to trim their proportions. I am quick with the recommendations presented, you can take off the same stone screed, so that it will serve you for a long time, and the whole work will borrow from you not a lot of time.

When working with the materials, it is necessary to know the proportions of cement and sand for screeding for several reasons.

The screed, which vir_vnyuє slabs of overlap, is prepared after the link of the box budіvlі. It is even more difficult to take in the middle the ready-made concrete from mixers at the stage of processing, which is most often done independently.

On the vіdmіnu vіd fаnаіnіv, pіdlog оn the soil аnd іnshі monolithic аlіѕо concrete structures, screeds сreated from pіskobetonu. The great reminder is the rubble they have during the day, the shards of stones, which are placed in ready-mixed concrete, reduce the productivity of the thin ball.

The proportions of sand and cement are regulated by the standards of the Joint Venture. The main characteristics of the construction material are two indications:

class - it is indicated, showing a vice in MPa, when a cube with an edge of 15 cm collapses with concrete, which gains a minimum of 75%;
brand - denoted by M, showing between the values of kg / cm²

Marking is indicated only by the class of construction material, and the brand value is presented closer to the new one. For example, for classes B7.5, B15 and B20, the brands M100, M200 and M250, vіdpovіdno, and for classes B10 and B12.5, the same brand M150, as well as for B25 and B27.5, the brand M350, vіdpovіdno.

Therefore, the specification of materials for concrete concrete cannot, in principle, be the same for different grades/classes:

М150/В10 - 1:3
M150 / B12.5 - 1: 2.8
M200 / B15 - 1: 2.4
M250 / B20 - 1: 2.2
M300 / B22.5 - 1: 1.8

It is possible to win with the winds, which is more convenient when the bunker is loaded with concrete mixers, or when the products are mixed at the zebra.

Zamіshuvannya for an obligatory zruchnіshe on budmaydanchik.

Prote zamovlyat non-metallic material (pisok) and kupuvati cement zabudovnik brought in mass parts - tones and kilograms, apparently. For the translation of the obligation into the masu, the following words are used:

bag of cement - 50 kg = 38.5 liters of bulk product or 3.85 buckets 10 liters
1 ton of cement - 0.77 cubic meters of material or 77 cebers, obviously
1 t pіku - borrows a volume of 0.61 cubic meters or 61 buckets of material

Like a forgetful person, you pay for non-metallic material in cubes, you don’t need to transfer anything.

When designing and folded curtains, the following should be oriented to the values indicated in the lower table for aircrete B12.5:

Or a similar table for the selection of concrete B15:

The calculation of the obligation of the screed represents a lot of folding through the retail of її comrades on the other plots. Therefore, either take a larger value at the lower point of the overlap plates, or the middle one with a 25% margin.

When calculating the obsyagіv slid vrahuvat differences in the heights of the base.

Important! The screed should be poured in one step.

Selected materials

The stores of budmaterials sell sumish TsPS and PTSs (deposit from the marking of the picker). On the packaging it is indicated the number of components and the necessary amount of water for the completion of design efficiency. To save the budget for repairs, individual forgetters often purchase window materials and replace them on their own. Tsey napіvfabrikat otrimav the name of the carving.

Pisok

At the standard assortment of post-workers of non-metallic materials, there is no sound for pisco-concrete. The best option for this construction material is a warehouse:

sand fraction 0.5 mm - serve as a fresh reminder;
sand fraction 3 - 7 mm - vikoristovuetsya replace traditional crushed stone as a great reminder.

Tsya umova is not beaten by all dry sums, but the pickers of non-metallic materials divide the sand into fractions rather rarely. That forgetful person has to be satisfied with the assortment of quarry, river budive pisk.

To ensure a high operational resource of the screed, it is necessary to correct the nuances:

near the quarry sand, there is a large amount of clay;
in any case, the clay looks very unsafe for concrete structures and vibrations;
when water penetrates into it, it swells up, swells up when it freezes;
the structure of the construction material is weakened by the number of microcracks;

Tom best options for an individual memory book є:

river sand - clay is imitated by flow, protein particles may have a rounded shape and low adhesion at the structure of cement stone;
mity kar'erny pіsok - pіshchinki tattered form mіtsno zchіplyuyutsya with knitting that one one;
granotsev is like a great astringent - the particles of this material are smaller, lower stone crushed stone, and the minerality is approximately the same as quartz.

Granots_v zam_st crushed stone for concrete screed.

For screeds, portland cement grades M400 and more are used. The presence of additives at the boundaries of 20% by weight, 2 - 3% gypsum is allowed to enter the cement warehouse for the purpose of regulating the accumulation of structural material.

Important! When buying a slick product, pay attention to the date of packing, shards of 100% characteristics are saved for less than 2 months. Then we spend cement at 20% or 30% after 3 months and after the repair, depending on the case.

The material may be moved, so as not to buy counterfeit goods, check the packaging for the presence of the requisites of the maker and the instructions for sizing.

Water

On the view of the foundations and concrete blocks, natural water basins at the stage of processing, do not sound vicorous. Therefore, the quality of the lead for locking is satisfied due to the standards of the Joint Venture and GOST 23732:

salt content not more than 5 g/l;
suspensions not more than 0.2 g/l;
pH at the boundary 4 - 12.5 units;
total availability of barvnikov, oliy, fats, naphthoproducts;
phenol, tsukor, PAR not more than 10 mg/l.

Fiber

The replacement for laying standard meshes can be made with micro-reinforced screeds in mast. For this, when mixing concrete, fiber or steel, propylene, basalt, glass fiber are added to the new one.

Steel fiber is not suitable for thin screeds, shards of 5-12 cm of wool with a diameter of 0.5-1.2 mm can be washed from a new post-laying.

The best option for vibrating screeds and balls in concrete for the preparation of self-fueling cures (baths, showers) is basalt-fiber-reinforced concrete. Deformations in the form of high values of operational stresses are transferred by this material at the spring mill without any marks.

Basalt fiber.

For shaping cement stone in astringent vistachaє 25% rind in yogo masi. However, with such a hardening, the concrete becomes hard, the strength decreases sharply. The main special term W / C is water-cement spiving, which is the main criterion for the strength of concrete structures. For screeds, W / C = 0.5 - 0.6 units are accepted for adjusting the natural moisture content of the sand.

Injection of water-cement spіvvіdnoshennia on the structure of concrete

To increase the plasticity of the sum, special additives are added to the warehouse for concrete. The most popular superplasticizer C-3, which is added in a quantity of 250 - 500 ml per bag of cement. Narodny Zazobє whether there is a concentration of miyuchy zasіb - a tablespoon for the batch of concrete mixers.

In this way, for ensuring a high operational resource, it is necessary to increase the value of the proportions of the components of the screed. For independent rozrahunku kіlkostі pіsku and cement vozanі real norms vitrati.
