The article presents a study to establish the possibility of obtaining polymodal silicate dispersions (SCD) based on common natural silicacontaining raw materials (gaize) and of using such dispersions as fillers and additives for cement compositions and assesses their effectiveness. Gaize, construction quicklime, and sucrose were used as modifying carbohydrates and silica-containing raw materials for the mechanochemical synthesis. The SCD technology includes the stages of raw material dosing, combination, and wet grinding in a ball mill, separation of the solid phase of the suspension by filtration (in drum or pressure filters) and its thermolysis in a thermolysis chamber, followed by short-term dry grinding of the thermolysis products in batch or continuous mills. The results are presented for the analysis of silicate-calcium dispersions with various ratios of the initial components. The efficiency of using SCD as a component in a composite binder or a finely dispersed mineral additive in cement-sand composites is demonstrated, which introduces mechanochemical synthesis of calcium silicates as a promising technology for processing gaize into effective fillers and additives for construction purposes.
The study was carried out under the grant issued by the Russian Science Foundation (project No. 19-19-00263).
