摘要
制造水泥高耗能,粉煤灰质量不易控制,河砂资源日益匮乏,而采石行业石屑尾矿无法处理,不只浪费资源而且污染环境。但将石粉与石屑分离也是需要大量人力物力的。笔者通过一些室内试验,来分析不进行筛分情况下石粉在混凝土中的应用。
It is not easy to control the quality of fly ash in the manufacture of cement and river sand resources increasingly scarce,and stone industry quarry tailings can not be handled,which wastes resources and pollutes the environment.But the separation of stone powder and stone chips also requires a lot of manpower and resources.The author passed some indoor tests to analyze the application of stone powder in concrete without screening.
