高掺量粉煤灰混凝土在高等级公路中的应用

Application of fly ash concrete in high-type highway

通过大量试验得到高掺量粉煤灰混凝土在高等级公路中应用的优化配合比 ,其特点是路面耐磨性能好、抗折强度高 .研究成果应用于摊铺机施工的实际工程 ,取得了很好的经济效益和社会效益 .

In this paper an optimized proportion of concrete with fly ash is obtained, which is suitable to be used in highway constructed by a spreading machine. Results show that the concrete has high abrasion of the concrete is lower than that of the traditional concrete.
