Aerated concrete is considered a good quality material, which is intended for the construction of buildings and outbuildings.
A special adhesive is required for its installation.
The amount of adhesive mixture must be calculated accurately. We'll talk about this later in the article.
When erecting a structure, it is assumed that the building must be durable and reliable.
In order for aerated concrete masonry to be of high quality, aerated concrete blocks must be laid using special glue. Masonry mortar differs from cement in its quick preparation and ease of use. The glue is used only for solid blocks with precise geometry.
The advantages of special adhesive for aerated concrete are as follows.
Consumption of glue for aerated concrete is determined in the following proportions: for 1 m3 there is 1.5-1.6 kg of dry mix at layer thickness 1mm.
This calculation is suitable for a flat surface. Based on this, the consumption per cubic meter should be approximately 15 to 30 kg.
For one square meter, the average consumption of glue is 25 kg, that is, one bag.
The above figures are theoretical calculations.
In practice, completely different results are obtained, for example, 1.5 bags per cubic meter.
This difference is influenced by the following:
These facts must be taken into account before calculating the adhesive consumption.
Be sure to read the instructions on the package before starting to prepare the glue!
The adhesive composition should be chosen, depending on the season.
For winter use frost-resistant concrete glue.
It contains antifreeze additives in its composition.
This mixture is kept warm and kneaded using hot water.
The finished mixture is taken out into the street in an insulated container and under a lid.
The adhesive must be applied fairly quickly.
In its composition, glue for aerated concrete should have:
To make the consumption of glue as economical as possible, it is necessary to use the following tools:
The aerated concrete block must not be wetted before applying the adhesive!
The block must be cleaned from dust, grease and other contaminants.
Excessive humidity of the aerated concrete block must not be allowed.
Apply the adhesive with a notched trowel or carriage. After applying the glue, it should harden, and only then the excess is removed.
Adhesive mixtures have an advantage over sand-cement mortar.
Consumption of the adhesive composition depends on many factors, they must be taken into account.
Hire professionals to avoid making mistakes.
But only hire already proven specialists.
It is necessary to check that all the tools for preparing and applying the aerated concrete adhesive are available.
It is necessary to purchase glue in advance that meets all available parameters.
In the event that you nevertheless decide to lay aerated concrete yourself, then it is better to do this in the warm season (summer) and follow all the available instructions.
Before starting work, carefully calculate everything, think it over and make a truly correct choice.
We wish you good luck in your endeavors!
