Experimental Study on Fly - ash Concrete

In the paper,it is introduced the design of proportion for serials of fly-ash concrete.It is concluded the service behavior of fly-ash concrete with content of 25% is the best by testing the proportion of fly-ash concretes with content of 20%,25% and 30% separately.The advantages of fly-ash concrete are excellent service behavior and little slump loss of concrete as well as suitable for commercial concrete and long-distance transport.With it,the construction quality could be improved,cement could be saved,cost of concrete could be reduced and resources could be saved,etc.
