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.
