水泥粉磨方式对水泥性能的影响研究

Study on influence of cement grinding methods on cement properties

本试验选取目前工业生产中常用的三种粉磨方式生产的水泥进行比表面积、水泥净浆流动度、水泥水化热、混凝土工作性能、混凝土抗压强度和水泥颗粒级配的检测,检测结果显示半终粉磨为最优粉磨方式,并且在生产中采用比表面积和45μm细度控制指标的效果基本相同,结合电耗等指标,建议采用半终粉磨方式进行粉磨,比表面积控制到(370±10)m~2/kg,水泥性能最优。

This experiment selected cement produced by three commonly used grinding methods in industrial production to detect specific surface area,cement slurry flow,cement hydration heat,concrete performance,concrete compressive strength and cement particle gradation.The results showed that semi-final grinding is the optimal grinding method,and the effects of specific surface area and 45μm fineness control index in production are basically the same.Combined with power consumption and other indicators,it is recommended to use semi-final grinding method for grinding,the specific surface area control to(370±10)m2/kg.Meanwhile the cement performance is optimized.
