Experimental Study on Compressive and Tensile Strength of Composite Hydraulic Concrete With Different Content of Fly Ash and Slag
In this paper,the variation of mechanical strength of hydraulic concrete under different fly ash content(10%,20%,30%)and dif-ferent slag content(15%,30%,the proportion of slag to fly ash)was studied.The results show that the slope of the evolution curve of con-crete mechanical strength-fly ash content is larger with the longer curing time.With the increase of curing age,the slope of the evolution curve of concrete compressive and tensile strength-slag content is larger.When the fly ash content is 20%and the slag content is 15%,the com-pressive strength and tensile strength of concrete are the best.
