所谓机制砂即人工砂,其制作是将大粒径的岩石状固体物进行机械破碎筛选成0~5mm的颗粒。机制砂大多用于商品混凝土搅拌站、建筑砌块或砌筑砂浆,商品混凝土搅拌站一般将机制砂与细沙搭配成细度模数达中砂质量指标的砂作细骨料生产商品混凝土,降低了商品混凝土的材料成本。本文针对不同的机制砂进行化学分析,将不同化学成分的机制砂分析 The so-called sand that is artificial sand, its production is the large size of the rock-like solid material was crushed to 0-5mm mechanical screening of particles. Most of the sand used for commercial concrete mixing plant blocks, building block or masonry mortar, commercial concrete mixing plant sand and fine sand with a general fineness modulus of sand quality indicators of sand as fine aggregate production of commercial concrete, Reduce the material costs of commercial concrete. In this paper, chemical analysis of different mechanism of sand, the chemical composition of different sand analysis
