二次投料配制钢纤维粉煤灰混凝土、粉煤灰混凝土试验研究

Research on Twice Mixing for Compounding Steel Fiber and Fly Ash Concrete Tests

利用粉煤灰材料活性 ,采用二次投料原理 ,通过室内试配钢纤维粉煤灰混凝土和粉煤灰混凝土试验 ,以及铺筑试验路段的验证 ,表明该材料能满足路面强度要求 ,还可降低水泥用量和工程造价。

Based on the activity of the material of fly ash, using the way of twice mixing, through the test of compounding steel fiber and fly ash concrete indoor and in field, it has proved that this material can not only satisfy the requirement of strength of road but also reduce the quantity of concrete and project cost.
