Performance Comparison Of Fly Ash Concrete And Ordinary Concrete

1、Hygroscopicity, water secretion, hydration, creep, segregation, sulfate resistance and alkali aggregate reaction resistance are improved compared with ordinary concrete;
2, slump loss, compactness, maximum compressive strength, flexural and tensile strength, shrinkage, impermeability better than ordinary concrete;
3, setting time, modulus of elasticity, abrasion resistance and frost resistance are similar to those of ordinary concrete;
4, early strength, resistance to carbonation is not as good as ordinary concrete.
