C40级粉煤灰全矿渣混凝土即粗骨料用矿渣碎石、细骨料用矿渣砂、掺合料用粉煤灰配制的各类稠度的混凝土,其技术性能经济指标值优于普通混凝土,在建筑市场颇有竞争力。 目前生产C30级及以下等级混凝土采用细骨料为矿渣砂,C40级混凝土采用细骨料为天然砂,搅拌站在生产过程中随着混凝土强度等级的变化颇繁更换骨料,骨料易错易混,质量难保,工期难保,影响制品公司的效益。 近几年鞍山市高层建筑物群日益增多,混凝土向高强化发展,C40级混凝土用需求量倍增,若C40、C30、C20、C10级系列混凝土细骨料全部采用矿渣砂,将是制品公司材料史上的一次革命,带来的是巨
C40-grade fly ash whole slag concrete is concrete of various thicknesses prepared with slag gravel for coarse aggregates, slag sand for fine aggregates and fly ash with admixtures, and its technical performance economic index value is better than ordinary concrete. In the construction market is quite competitive. At present, the production of C30 grade and below concrete uses fine aggregate as slag sand, C40 concrete adopts fine aggregate as natural sand, and the mixing station changes with the change of concrete strength grade in the production process to replace the aggregate, and the aggregate is easily misplaced. Miscible, difficult to guarantee quality, difficult to guarantee the duration, affecting the efficiency of product companies. In recent years, the number of high-rise buildings in Anshan has increased and the concrete has advanced to a higher level. The demand for concrete for C40 grades has doubled. If all the C40, C30, C20, and C10 series of fine aggregates for concrete use slag sand, it will be the material of the product company. A revolution in history brought great
