One urgent issue today is reducing CO2 emissions worldwide. In particular, the study of using sulfoaluminate cement to create less CO2 is a suitable solution. The paper presents compound additives' influence on the composite binder's standard consistency. Binders such as sulfoaluminate cement, natural gypsum, and tripoli are used as additives. The resulting binder's standard consistency was determined per GOST 310.3-76. Box-Wilson central composite design method was used to simulate the test results. The results obtained are presented as the surface of the second-level regression equation, which describes the dependence of the mixed binder's standard consistency on the additives' content. Research results have been obtained from compositions of composite binders with maximum and minimum standard consistency. Based on the analysis of experimental data, conclusions were drawn about the possible mechanism of the effect of the introduced additives on the consistency of the cement paste.
