In this article, the properties of thermal insulation solutions, which are one of
the current exercises in construction works, were studied. Optimum compositions of thermal
insulation solutions were worked out in vermiculite, which is widespread in the region of our
country.

Nawadays, many countries in the world do not consider thermal energy to be among the
most expensive types of energy, because thermal energy is not renewable . Thermal energy is only
used for heating. It is for this reason that most of the countries that we consider to be developed
today have banned the construction of buildings and structures without the use of thermal
insulation construction materials. It is possible to heat the walls of individual multi-story
residential buildings by 30-40% [1]. Separate building materials are not effective in terms of
thermal insulation. Special heat-insulating building materials are needed for the left-hand side. It
is necessary to maintain the microclimate in the thermal insulation of the building with a tin
hammer. After choosing the necessary wall construction materials for the building, it is necessary
to choose the right solution. The reason is that the strength of solutions and the parameters of heat
transfer should be close to the parameters of the material used in the wall construction. For
example, if the thermal insulation of the wall construction is made of foam concrete-like material,
in such a case, it is impossible to use apivai building solution, because the heat transfer of the
apivai solution is 4-5 times more than the heat transfer of foam concrete. This affects the thermal
insulation of the building. Apart from this, it is important that these solutions have a jeteral level
of the required volume base. Based on the above, we can say that the use of vermiculite is one of
the best ways to make thermal insulation solutions in the region of our country. In our Izertlew
group, the effect of vermiclutide on construction solutions was determined by determining the
optimal composition of thermal insulation construction solutions.
Keeping the air in the working part of the building is one of the actual issues in construction
works today. This issue is one of the issues that must be resolved in the regions of our country.
According to the data, it was found that most of the heat loss in buildings comes from protective

structures (~30%), roof coverings (~10%), mirrors (~25%), ventilation systems (~25%), and heat
radiation (~10%) [2] .
In insulated constructions, there are always places where heat is absorbed at a level that
cannot be taken into account (places with cracks, crevices, etc.). All such places have a negative
effect on the heat distribution of the building, and as a result, such places do not play the role of
heat and cold air. We can give an example of such air ducts, such as plastered blocks, and even
doors.
The solution of the solution in the brick doing works does not fulfill the function of the air
copy, as a result of which the thermal technical characteristics of the product are reduced. It is
possible to use special solutions during the construction of walls made of ceramic tiles or blocks.
However, the thermal insulation properties of such solutions are estimated to be 4-5 times less than
the properties of materials used in wall constructions. The thermal insulation properties of the roof
coverings are explained in detail in the constructions of the public sector. Because of this, printing
plays an important role in thermal insulation works. If the thermal insulation of the roof coverings
is good, then additional equipment is not required to maintain the atmosphere of the working
environment.
We can satisfy the demand for effective, high-strength, and bio-resistant heat insulation
building solutions of the building complex by using solutions containing polyoxylgen vermiculite.
Such solutions can improve the quality of construction works and environmental cleanliness with
minimal material and physical resources [3] .
Multi-flammable vermiculite is obtained by burning in vermiculite furnaces with fine sand.
When vermiculite is heated to a temperature of 1000 °C, it becomes a crystallized clay, and as a
result, it expands (enlarges) quickly. The water-induced pud has a perpendicular effect on the
fracture planes, and the mica plates are separated from each other, and the size of the particles
increases by 6-15 times. After being diluted, vermiculite retains its weight as a result of the air
between the mica plates. Multi-inflammable vermiculite is an odorless, scaly, soft, coarse-textured
material. Vermikluite has a good sound and heat insulation properties, but it also has the properties
of compressibility in a very large volume. Vermiculite can absorb up to 500% of liquid by weight.
However, the vermiculite liquid was well absorbed, and it almost didn't go away. Air permeability
is around 100%, and vermiculite permeability can be as low as 10%.
In the works of research, multi-functional vermiculite with a particle size of 0.6 mm was
used. This vermiculite fully meets the GOST 31189-2000 standard.
Thermal technical properties of multi-expandable vermiculite are presented in the table
below.

One of the disadvantages of multi-fertilizing vermiculite is that its particles are in a rough
shape, it has poor liquid absorption, and the mixture of solutions does not have the ability to be
jetted. In addition, the low mechanical strength of vermiculite particles due to the weak connection

between separate layers has an adverse effect on the adhesion of solutions. Finally, it is
recommended to use fractionated vermiculites, because such fractions are cheap and expensive.
To improve vermiculite properties, it is possible to add different types of components. They
must have the following properties.
Plasticizing compounds have water-reducing properties, and the vermiculite particles
present in the aggregates help to improve the water/cement ratio. As a result, the viscosity of the
solution increased, as well as the strength indicators.
The viscosity of the particles with the air self-gravity effect affects the viscosity of the
solution. The one in the solution is characterized by the kernel effect, the thermal conductivity of
the solution.
Adhesion properties are affected not only by the adhesion properties, but also by the
adhesion properties between vermiculite particles.
In Research work, the effect of additives on solutions in vermiculite was studied. In order
to compare the results, a standard sample of 10-12 cm diameter was prepared. The admixtures
were selected in proportion to the cement mass. A cement/vermiculite ratio of 1/1 was used in
samples of ½.

Based on the obtained results, the optimal combination of vermiculite solutions with
superplasticizers can be said to be C-3 and Poliplast SP-1 superplasticizers with a ratio of 0.8% by
cement mass. The viscosity of the solutions of this composition was determined along with the
strength of the heat transfer principle. The initial value of such solutions was 0.185 Kcal/mK, and
after adding superplasticizers, this value was equal to 0.140 Kcal/mK.
