摘要
对机制砂中的石粉含量对混凝土性能的影响进行了试验研究。对无河砂地区 ,以机制砂代替河砂进行混凝土施工具有明显的经济效益。
An experimental research has been done on the effect of crusher dust content of machine crushed sand on concrete performance, which provides with reference for using machine crushed sand instead of river sand in concrete works at no river sand areas.
