The influence of calcium sulfate additives on the properties of quick-setting cement compositions.

The properties of compositions based on mixtures of Portland cement and Secar 38 R aluminous cement with the addition of hemihydrate of calcium sulfate are examined. The effect of α- and β-hemihydrate of calcium sulfate addition on the time of curing, kinetics of hardening, deformation and heat release during hardening are discussed.
