水泥标准稠度用水量的大小直接影响到混凝土的工作性能。本文针对四种不同来源的水泥的标准稠度用水量差异性,从它们的矿物组成和颗粒分布状态特点进行了关联分析,分析结果表明:水泥细颗粒部分的矿物种类和数量是影响用水量的重要因素,细颗粒部分的粘土类和熟料类的矿物占比越大,水泥的需水量越大。 The standard consistency of cement water directly affects the size of the concrete performance. According to the difference of standard consistency water of four kinds of cement with different origins, this paper makes a correlative analysis on the characteristics of their mineral composition and particle distribution. The results show that the type and quantity of minerals in the cement fine fraction are important to water consumption Factors, the greater the proportion of fine-grained clays and clinker minerals, the greater the water requirement of the cement.
