对粉煤灰混凝土性能的探讨

Approach to Performance of Fly Ash Concrete

阐述了粉煤灰和混凝土的掺入方式和掺量问题,粉煤灰掺入混凝土后改善混凝土内部结构,节约了部分水泥,作为路面材料从抗折强度、和易性、耐磨性、抗冻性等都有了相应的提高,特别是后期强度较高。因此这种混凝土应该大力提倡应用。

The paper elucidates the way to fly ash admixing into concrete and the admixing amount, expounds also the improvement of concrete＇ s inner structure after fly ash admixing into concrete, appropriately heightening the pavement＇ s bending strength, workability, wearability and frost - resistance, especially the later stage strength. So such concrete should be energetically encouraged.
