粉煤灰混凝土抗压性能的试验研究

以C30混凝土为基准，将两种粉煤灰分别按照5种设计掺量等质量替代水泥，研究了粉煤灰对混凝土抗压强度的影响。试验结果表明，掺入的粉煤灰品质及质量不同，对混凝土强度的影响程度不同；粉煤灰混凝土的强度前期增长较小而后期增长较大；粉煤灰的等质量最佳替代水泥量为30％。

Pilot Research on the Compression Resistance of Fly-ash Concrete

Taking the C 30 quality concrete for standard,put two fly ash into C 30 quality concrete respectively in which one takes the place of equally qualitative cement according to five designed incorporations in order to research the influence of fly ash on the compressive strength of concrete.The results of the experiments indicate that the different qualitative dosage of fly ash would give rise to different effects on the compressive strength of concrete:the compressive strength of fly ash concrete grows slowly in the previous stage but quickly in the later stage;the best incorporation of fly ash is 30 % for substituting for the equal quality of cement.
