Laying of expanded clay blocks by one's own hands: step-by-step instruction, technology, masonry mortar

If the claydite concrete blocks are laid by themselves, a step-by-step instruction will help you to do the work correctly. Such manipulations are not particularly difficult, which is why it is possible to do business independently, without recourse to specialists. However, it is necessary to familiarize yourself with the technological features, as well as to find out what kind of solution is suitable for laying claydite-concrete products that are produced by the pressing method, during which water, sand, cement and expanded clay are used.

Varieties

Ceramsite concrete blocks, the pros and cons of which are described in the article, is a safe, environmentally friendly and lightweight building material. Thanks to the presence of expanded clay, the products are porous and characterized by high thermal insulation qualities. Before you start working, you can prefer blocks of different sizes, but the most common are those that have the following dimensions: 390h300h188, 390h190h188. These products are used for walls, whereas blocks with dimensions of 390х190х90 mm should be preferred for the formation of partitions.

Characteristics

The material can be solid or hollow. The first variety has a higher strength, but is inferior in terms of heat insulation properties to hollow analogs. If it is planned to strengthen the walls or partition, it is necessary to purchase blocks in which furrows were formed at the production stage for reinforcement. This is due to the not too high strength of the material.

Preparation of materials and tools

If claydite concrete blocks are laid by their own hands, the step-by-step instruction should be previously studied by the master. It requires the preparation of materials and tools. You will need a rubber hammer, a tape measure, a trowel, a level, a cord, a plumb bob, and also a Bulgarian. Do not forget about the presence of a shovel, as well as a container for the preparation of a solution. Alternatively, a concrete mixer can perform. If you intend to build walls, it is important to ensure the availability of scaffolding, which you can manufacture yourself. The foundation of expanded clay blocks can also be erected. To form it, as well as for the construction of walls, you will need water, cement, sand or a special dry mortar intended for masonry. If a heater is used, stacked simultaneously with the installation of the blocks, then it is important to take care of its availability.

Mortar for the installation of expanded clay products

If the claydite concrete blocks are laid by their own hands, the step-by-step instruction presented in the article will allow you to familiarize yourself with technological features. In the process of work can be used a solution based on sand and cement, in place of which often used adhesives used for masonry. In the first case, mix cement, sand and water, keeping the proportion of 1: 3: 0,7. It is important to prepare cement grade M-400 or higher. The volume of the liquid can be adjusted depending on the moisture content of the sand. The solution must have a plastic consistency, which will make it easy to seat the products. However, it is important to rule out the spreading of the mixture.

Construction dry mixes

When clay clay concrete blocks are laid by one's own hands, a step-by-step instruction should be read in advance, this will help to avoid a lot of mistakes. If you decide to use a dry construction mix, then it must be mixed with water, following the instructions given on the package. Such compositions are plastic and allow to reduce the thickness of the formed joints. However, such a solution will cost more than a cement-sand mix. One cubic meter of masonry will need 40 kilograms of the finished mixture. The consumption of any solution will depend on the thickness of the joints, which can vary from 6 to 9 millimeters when using a cement-sand mixture.

Preparation of the solution

If you decide to use claydite-concrete blocks, reviews of house owners should be read in advance. They overlap with the characteristics of the products that were described above. Thus, according to the buyers, in order to build a warm house, the walls of which will not exert excessive influence on the foundation, claydite concrete should be used. Among other things, this material, as consumers emphasize, has a fairly affordable price. Builders and home masters note that the use of such units does not require the need for ordering construction equipment, which would entail additional costs. If you decide to choose claydite-concrete blocks, the reviews of the owners of the houses will definitely allow you to decide on the choice. For the preparation of cement-sand mixture, in their opinion, it is preferable to use a small concrete mixer, the volume of which will correspond to the amount of composition produced in 2 hours. The solution should be constantly mixed, which eliminates its delamination. In this case, the mixture will retain plasticity and uniformity. Especially it concerns the composition of sand and cement, which are devoid of plasticizers. If you decide to use a ready-made building mix, then it is recommended to stock up the mixer with a nozzle, which is installed on an electric drill. With this approach, it is important to prepare a capacity of the appropriate volume.

Masonry Methods

Before the masonry mortar is prepared, the wizard must decide which method of work will be used. This will be affected by the planned thickness of the wall. You can stack products in half a block, in one block, 60 cm wide, with two parallel walls in a half block, and also in a block with a facing brick. If you decide to use a technology that involves laying a wall wide in a block, it is important to alternate and tie the knobs and spoon rows. If the products are installed in a width of 60 cm, it is important to ensure the ligation of the blocks, leaving voids between them. The technology, which provides for the arrangement of two parallel-oriented systems, laid in a half-block, is carried out in parallel with the placement of a thermal insulation material between them. If it was decided to use the method of laying in the block, and afterwards the brick will be lined, then the insulating material will also be laid between the formed walls.

Nuances of works

After the mortar for the masonry is ready, you can start work. Begin the process from the corners of the building. A layer of 3 cm thick mortar is laid on the layer of waterproofing. The shrinkage of the products is done by pressing and tapping the surface with a rubber hammer. If you decide to build a house of expanded clay blocks with your own hands, then the position of the corners should be controlled with the help of building and water levels. Between the formed corner blocks it is necessary to pull a cord on which the laying of all series along perimeter of construction will be carried out.
