AbstractAbout AuthorsReferences
Results of the study of properties of a cement paste with different additives are presented. It is shown that the same additive works differently with different cements. The study of properties of mortar and cement mixes on the basis of different cements and with different additives is also presented. Preservation of mobility of mortar and concrete mixes has been investigated on the example of different cements. The results of physical and mechanical tests of mortars and concretes show that superplasticizers of a polycarboxylate type have the best compatibility with cements, and superplasticizers on the basis of clear lignosulphonates have the worst compatibility.
