AbstractAbout AuthorsReferences
A comprehensive assessment of the process of intensification of grinding of Portland cement clinker is given, as well as an analysis of the strength characteristics of early strength cement is presented. The basic physico-chemical properties and characteristics of modifying additives are considered. The influence of domestic grinding intensifiers on early strength in cement hardening systems has been established. Special attention is paid to the kinetics of the grinding capacity of Portland cement clinker depending on the specific surface of the particles. The greatest attention was paid to the study of the characteristics of samples containing additives of Polyplast LLC. The increase in the early strength of hardening systems containing additives IP-1 and IM-2 of Polyplast LLC is 3.7 MPa. In the proposed formulations, there is also a decrease in the coefficient of water separation.
