Effective use of natural raw materials and fuel-energy resources, introduction of local mineral raw materials and modern efficient technologies into the production process is one of the urgent issues of today. In this regard, a number of positive activities are being carried out in our Republic.
Taking into account the quality indicators of the concrete constructions of the buildings and structures under construction, taking into account their earthquake resistance, strength, and high parameters, it is necessary to accelerate the research work aimed at reducing the geometric dimensions and reducing the weight. , the task of reducing the consumption of energy and resources in the economy, widely introducing energy-saving technologies in production" is defined.
The results of scientific-theoretical and scientific-practical research conducted in the field of construction materials are the basis for the improvement of production processes and the emergence of new innovative ideas.
The results of the study of the effect of the type of filler used in the composition of heat-resistant mortar dry construction mixes (QQQ) on the heat-insulating, hydrophysical and deformation properties of this construction finishing coating;
The regularity of changes in the physical-mechanical, technological, and rheological properties of the calcareous finishing composition obtained by using it as a chemical additive to the mixture of hydrosilicate and hydroaluminosilicates on the basis of hydrosilicate and hydroaluminosilicates;
composition and production technology of heat-insulating dry construction mixes (DKK) for finishing aerated concrete. One of the ways to achieve this desired result is the use of chemical additives in production.
The demand for energy-efficient and environmentally friendly building materials is increasing not only in Uzbekistan, but also in the whole world. To meet these requirements, the material should be as light as possible and strong at the same time. In today's advanced age, the quality of materials with these qualities is certainly increasing. Let's compare the modern wall heat-insulating and energy-saving materials that can be used in the conditions of Uzbekistan.
We will conduct the comparison in relation to foam concrete, which is the subject of the master's thesis.
30 cm thick foam concrete protects the heat
2.25 m concrete wall
1.15 m brick wall
50 cm expanded clay concrete
26 cm gives a wooden brush.
