Abstract

Dry mixes of various functional purposes are widely used in construction works. Modifying additives are introduced into the composition of dry building mixtures to improve various characteristics of finishing compositions and coatings. Foreign companies supply most modifying additives, this significantly increases the cost of production of dry building mixtures. Therefore, the urgent task is to develop domestic modifying additives. The paper proposes the use of modifying additive for the finishing of aerated concrete in calcareous heat-insulating finishing compositions, the mineralogical composition of which is consisted of hydrosilicates and calcium hydroaluminosilicates. The expediency of the adopted two-stage technology for the synthesis of the modifying additive is proved. The synergistic effect of the modifying additive influence based on a mixture of hydrosilicates and calcium hydroaluminosilicates on the structure formation of lime composites is established. It is revealed that the use of modifying additive increases the compressive strength, the water resistance of lime composites and the speed of the set of flexible strength of the lime composition. The modifying additive, the mineralogical composition of which is represented by hydrosilicates and calcium hydroaluminosilicates, is used in the formulation of thermal insulation of dry mixes designed for interior and exterior walls of aerated concrete.
