Effects of polycarboxylate flexibilizer and mineral additives on strength characteristics of cement composites

The paper presents the results of a study of the effects of mineral additives of various compositions (silica, aluminosilicate, sulfoaluminate, carbonate) and polycarboxylate flexibilizer on the mobility, density, and compressive strength of cement systems. Optimal concentrations of additives, which make it possible to obtain modified cement composites with increased strength indicators, have been found.
