Title of the articleThe research the influence of thermoactivated mixtures on the properties of blended cement
Abstract.Problem statement. The aim of the research is the development of complex additives based on the thermoactivated synthetic mixtures of clay and limestone with calcite content of 87 %, optimization of the composition and thermal activation parameters, and the study of the influence of the received complex additives on the properties of blended cement stone. Results. The main results are that the developed compositions of complex additives based on the thermoactivated mixtures of clay and limestone. The physico-mechanical, physical properties of the obtained mixtures and their influence on properties of blended cement are investigated. Conclusions. The significance of the results for the construction industry lies in the fact that the results of the experiments allowed to establish the possibility of replacing up to 20 % of Portland cement with a complex additive of thermoactivated mixtures of clay and limestone without loss of strength of the obtained blended cement stone. The strength of the blended cement stone at the age of 28 days amounted to 90-95 % of strength of control cement sample.
Keywords.blended cement, polymineral clay, limestone, kaolinitic clay, cement stone.
