In the article results of researches of influence of the synthesized fillers based on the calcium silicates on properties of coverings based on the limy dry construction mixes are presented. High hydraulic activity of the synthesized fillers is established. Decrease of amount of free lime in limy samples with additive of synthesizable hydrosilicates, increase of durability are revealed.

The following article presents information on the regularities of hardening of lime construction mixture samples, which were produced while adding the supplement based on calcium hydro silicate. Mathematical model of influence of the percentage of precipitation supplement and the quantity of diatomite used for synthesis upon the compression strength of the samples has been implemented.
The article provides information about the possibility of using amorphous aluminosilicates as a modifying additive for dry building mixtures. The data on the synthesis of the additive, its chemical and physical properties are given. A recipe for adhesive dry building mixtures with the use of amorphous aluminosilicates is proposed synthesized by the proposed method. The technical and physical properties of tile adhesives made using amorphous aluminosilicates as a modifying additive are considered. The deformative properties of tile adhesive made on the basis of the proposed recipe are considered. The elastic modulus of the coating, shrinkage deformation, ultimate tensile strength, axial tensile strength and crack resistance coefficient are calculated. According to the results obtained, appropriate conclusions were made.
Provides information about the effectiveness of the introduction of modifying supplement in the formulation of dry mixes. Presents information about the technology of synthesis of supplement based on calcium hydrosilicates. It is established that the supplement has a high activity. A recipe for a lime dry mixes is presented using a supplement based on calcium hydrosilicate, synthesized in the presence of diatomite. The economic efficiency of the developed dry mixes with the use of calcium hydrosilicates has been calculated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
