EFFECT OF LIMESTONE POWDER ON THE PROPERTIES OF BLENDED РORTLAND CEMENTS

The article shows the relation between sustainability and cement manufacture that can be obtained by replacement of clinker with limestone additive. This decreases use energy resources reduces CO2 emissions in production. issue partial Portland substitution finely ground production market-oriented types type CEM II is solved on plant PJSC "Ivano-Frankivsk Cement". indexes physical-mechanical tests certified high early strength II/A-LL 42.5 R produced Cement" are given. Finely dispersed Portland-composite cements slag promotes a more complete synergic effect. It established, rapid-hardening blended powder provide technological, technical, ecological, economic effects prefabricated monolithic reinforced concrete.
