| Title of the article | Properties of a hardened Portland cement pastes with addition of clay polimineral clay with 40 % kaolinite |
| Abstract. | We investigated the effect of additives in Portland cement glinite on the properties of the cement stone. Glinit was obtained by calcination at temperatures of 400, 600 and 800 0С and grinded to a specific surface of 250, 500 and 800 м2/кg polymineral clay, which contains 40% kaolinite Arsk clay and metakaolin. Mineral additives of natural and technogenic origin calcined clay partially replace clinker component and they are one of the ways of increasing the technical and economic efficiency of production and application of Portland cement. We established that the addition of glinite, which based on this clay obtained by firing at certain temperatures and ground to a certain specific surface can more significantly improve the performance of physical and technical properties of the cement matrix than the corresponding content additive of metakaolin. |
