摘要

本文阐述了用石灰石添加剂替代熟料可获得的可持续性与水泥生产的关系。这减少了能源的使用,减少了水泥生产中的二氧化碳排放。在PJSC“Ivano-Frankivsk水泥”水泥厂,解决了市场导向型CEM II型水泥生产中部分波特兰水泥熟料被细磨石灰石替代的问题。给出了PJSC“Ivano-Frankivsk水泥”生产的高早强CEMⅱ/A-LL 42.5 R认证波特兰石灰石水泥的物理力学试验指标。灰岩在矿渣硅酸盐复合水泥中分散较细,促进了更充分的协同效应。快速硬化波特兰水泥与石灰石粉混合在预制和整体钢筋混凝土的生产中提供了技术,技术,生态和经济效果。

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