摘要
针对石子在破碎时产生了石粉 ,且石粉含量会对混凝土强度产生影响这一现状 ,结合过筛前后 ,碎石对混凝土强度的影响进行强度对比统计分析 。
According to stone power produced in stone shattering process and its influences on mechanical properties of concrete strength statistic analysis is made for the influences of crushed stone with or without powder on the strength of concrete. Conclusion is drawn that effect of the content of powder is insignificant.
