Title of the articleHybrid cements based on metakaolin with low content of Portland cement
Abstract.The article presents the study about the hybrid cements. The aim of our study was to investigate the influence of the content of tricalcium aluminate of Portland cement on the physical and mechanical properties of hybrid cement based on metakaolin and sodium sulfate. As the raw materials the Portland cement M500 D0 of Volski and Mordovian plants were used with low and medium content of tricalcium aluminate, respectively. As aluminosilicate component metakaolin was used, with the addition of sodium sulfate. The results of testing physical-mechanical characteristics of hybrid cements with a low content of Portland cement were shown. The influence of steam curing on the strength properties of hybrid cement was investigated. It is established that at the age of 1 day hybrid cements with a content of Portland cement 20-40 % have a strength in a 4-2,7 and 2,6-2 times higher than that of cement with no sample Volski and Mordovian cements, respectively.
Keywords.hybrid cements, mineral additives, metakaolin, sodium sulphate.
