How to use glue for concrete blocks?

has recently become very popular to use in the construction of various structures aerated concrete blocks.This is primarily due to the efficiency of this material, as well as high performance.The use of special tools and materials, such as a saw, adhesives for concrete blocks and others, can significantly improve the quality of work for laying these building elements.

adhesive composition aerated

adhesive for aerated concrete blocks is a mixture of dry consistency, within which are the following ingredients:

  • graded silica sand;
  • Portland cement without additives;
  • special supplements dispersion.

use of this composition significantly improves the quality of work performed, as adhesive for aerated concrete blocks allows to obtain a thin layer for connecting elements (about 2 mm).Whereas when using a cement-sand mortar intervals of 5 mm obtained, which increases the heat loss in the room.

Preparation composition

adhesive concrete blocks can be prepared by observing the following points:

  • mixture is diluted in a ratio of 10 kg to 2-2.5 liters of water, use a clean (oil-free) fluid temperature 30 ° C;
  • solution is prepared in a special container, mixing spatula or mixer;
  • finished mixture should have the consistency of thick cream, then you need to give the glue to stand for about 15 minutes;
  • before using the solution should be re-stir;
  • ready adhesive must be applied within an hour, in the case of longer term capacity is necessary to cover the film;
  • adhesive consumption in the aerated concrete blocks is approximately 2 kg of dry concentrate per 1 m2 of the working surface.

prepared adhesive composition has a high degree of education binding properties (adhesion), and plasticity, and the connection withstands temperature extremes, moisture and other environmental influences.

Laying with glue

adhesive for aerated concrete blocks (the price of which varies from 200 rubles per 25 kg) is easy to use.This will be useful to know the following points:

  • surface units should be equal, if the defects can be corrected by using the prepared adhesive solution;
  • pre-wetting of concrete blocks is not necessary;
  • adhesive is applied with a spatula, and the layer should be 2-8 mm;
  • blocks stacked, slightly pushing and turning;
  • position of building elements can be changed in 15 minutes;
  • strong bond of the adhesive mounting is formed per day and the final drying takes place within 72 hours;
  • this composition can also be conducted alignment joints in the vertical direction.

adhesive concrete blocks creates a strong connection, thus increasing the insulating properties of designs.The use of this composition will significantly improve the quality of the work performed.
