Optimization of the Synthesis Additive on the Basis of Amorphous Aluminosilicates

Abstract

Abstract The article presents information on the possibility of applying additive based on amorphous silicates in the lime dry construction mixtures. The methods of synthesis additive on the basis of amorphous aluminosilicates are investigated. Using the method of mathematical planning of the experiment, the optimal mode of synthesis additive was chosen. The compressive strength of lime samples with an additive based on amorphous aluminosilicates obtained at different synthesis times and the ratio of the solid and liquid phases is calculated. The studies and calculations show the effectiveness of the use of amorphous aluminosilicates in lime composites as a structure-forming additive. The lime mixture with the use of amorphous aluminosilicates is characterized by good workability and a high value of compressive strength equal to 2.4 MPa.
