Effect of calcined clays on the physical-mechanical properties of hardened Portland cement pastes

摘要

Recently, the attention paid by materials scientists to the research, development and application of Portland cements incorporated with calcined clays has substantially increased. This article presents the study results of how clays with different chemical and mineralogical composition calcined at different temperatures influence the properties of Portland cement paste. The results of this study allow us to conclude that it is possible to produce technically and economically effective supplementary cementitious materials for blended Portland cements based on the commonplace polymineral clays with relatively low energy costs on their thermal activation and grinding.
