How to make keramsit - advice from an online store of building materials

When planning the construction of your own house, especially in the conditions of modern, successive financial crises, the material component comes to the fore. And if it is quite difficult to save on finishing materials, the elements from which the foundation and walls are erected provide a good opportunity for this.

You can pour the foundation, significantly reducing the cost of its final cost, not hiring the workers, and doing everything yourself. Also, the cost will decrease if you do not buy ready-made concrete for pouring, but mix it in place, according to the proportions. The same applies to the construction of the outer walls of the house, and its internal partitions.

Claydite - the advantages and disadvantages

Recently, for the construction of houses, trying to use building blocks made of expanded clay.Expanded clay is a specially baked clay that has air voids inside, giving it a resemblance to a sponge. It is environmentally friendly. The advantages of this material abound:

· High strength. Allowed to build buildings, up to three floors. The material can easily withstand such a load;

· Moisture resistance. Does not absorb moisture, respectively, does not collapse when possible frosts;

· Eco-friendly;

· Has a high sound insulation;

· The material is not exposed to fire;

· High thermal insulation;

· Small specific weight that allows to erect buildings on light versions of the foundation.

· Low cost.

An additional "advantages" of this material is the ability to independently produce lightweight aggregate blocks with their own hands.

The disadvantages include ugly appearance, requiring subsequent finishing. But this is easily solved, for example, with the help of plaster and simple siding.

Types of production equipment

Making claydite blocks with their own hands requires a small amount of equipment.

1. Concrete mixer for uniform mixing of claydite-concrete components.At home, enough volume of 150 - 200 liters.

2. Forms for blocks. You can buy ready-made (new or used), or make your own. To do this, use the metal and the board. Standard parameters of the finished block are 390 mm x 190 mm x 190 mm. To increase the speed and volume of production, it is more rational to make forms consisting of several blocks at once. But you should not do more than 10 pieces in one cell, then there will be difficulties in extracting finished products. Types of forms may differ by the presence of voids in the block: without them, through voids and non-through.

3. Concrete vibrator. To reduce the amount of air in the concrete mass.

Components for claydite blocks.

1. Expanded clay gravel. Required strength P150 - 200, fraction size not more than 10 mm. There are options to establish the production of expanded clay at home, but it is quite time-consuming and requires a large area process. So if you have a small building, it is easier to buy.

2. Sand. It is not recommended to use ordinary river, preferably enriched with gravel, for a better result.

3. Cement Grades М400 - 500.

four.A variety of plasticizers. As them suit: liquid soap or laundry detergent. Approximately 1% of the total mass of the solution is required. As well as to increase plasticity, it is possible to add wood ash, lime or clay to the solution.

The process of manufacturing blocks

The production technology of lightweight aggregate blocks is quite simple, while respecting the proportions of the components and the sequence of their loading into the concrete mixer.

In order to obtain a qualitative homogeneous solution, dry mixtures are first mixed, and only then water is gradually added. The finished solution, at the exit, should resemble liquid clay.

The proportions of the components of the solution, provided based on the calculation of 100 kg of the finished mass, because at home, concrete mixers give the maximum such volume.

· Cement - 9.2 kg;

· Sand - 27.2 kg;

· Expanded clay - 54.5 kg;

· Water - approximately 9, 1 kg. The final amount depends on the consistency of the solution.

If it is not possible to measure out the components metered, use the following proportion:

• Cement - 1 part;

• Sand - 2 parts;

• Expanded clay - 8 parts;

• Water - 1.5 parts.

Mixing time will be approximately 6 - min.The resulting claydite is enough for the manufacture of 9 -10 pieces of blocks.

The finished mass is poured into molds located on a flat surface, preferably on a metal sheet. Using an electric vibrator, level the solution in forms, to remove air and more dense precipitated keramsit concrete. If necessary, remove the excess claydite, or add it if some form was not filled to the edge.

After holding for about 30 minutes, just this time should be enough to load the next portion of the mixture into the concrete mixer, extract the resulting blocks from the forms. Subsequent drying of the blocks should occur under a canopy, in order to avoid direct sunlight or rain. It is better to store them 4-5 in a row, on top of each other, laying a layer of boards or pallets, for better air circulation.

Ready-made blocks can be put into construction in one and a half to two weeks, however, ideally, it is desirable to let them get to their condition within a month, during which time the cement will gain its full strength. For work, for convenience, the blocks should be cleaned of irregularities.

As can be seen from the above, the production process of expanded clay concrete blocks, is quite simple and does not require special training. In this case, the cost of the finished unit is estimated at 20 - 30 rubles, and the market value today is 80 - 100 rubles. Even if we take into account the cost of delivering all the necessary components to the site, the cost of the required number of blocks to build your house will still be two times less than when purchasing them on the construction market.
