Title of the articleThe research of the influence of carbonate additives on the physico-mechanical properties of the blended cement
Abstract.The introduction limestone and dolomite additives in cement is one of the promise and effective way in reducing the CO2 emission. The results of research the influence of carbonate additives on the physico-mechanical properties of the blended cement stone are presented. As the carbonate additives Dobryatinsky and Kamaevsky limestone and dolomite Matyushinsky were chosen. The effect of temperature and curing conditions on the strength characteristics of the blended cement stone are shown. It was established that the physico-mechanical properties of the cement stone and the rheological properties of cement paste are depend on the chemical-mineralogical composition of carbonate additives. It has been shown that a significant impact on the physical and mechanical properties of the blended cement stone and water demand of cement paste with carbonate fillers the chemical and mineralogical composition of the original carbonate have, like the presence of clay impurities too. The highest strength of the blended cement stone occur with the addition up to 10-15 % of Dobryatinsk limestone.
Keywords.carbonate rocks, limestone, dolomite, blended cement.
