摘要
Abstract
The effects of manufactured middle sand, manufactured coarse sand, natural sand and polypropylene fiber on earlycracking of face slab concrete are studied through slab tests. The results show that using natural sand instead ofmanufactured sand or adding polypropylene fiber in manufactured sand can all effectively inhibit the emergence of earlycracks and increase the ability of concrete to resist early cracking.关键词
