Calcareous finishing compounds using fillers on the basis of synthesized hydrosilicates

It is proposed to use synthesized hydrated calcium silicates as a modifying additive in calcareous finishing dry building mixes. The effect of substances containing amorphous silica used in the synthesis on the activity of a modifying additive is determined. The use efficiency when synthetizing modifying additives of amorphous silica, in particular diatomite from Inzadeposits is shown. The differential thermal analysis of calcareous samples based on synthetized modifying additives is presented. It’s been found out that the introduction of hydrosilicatesfavors acceleration of the mechanical strength.
