Experimental Study on Composition Design and Performance of Foamed Cement Banking with Slag Powder
摘要
Abstract
The mixture ratio design parameters of FCB with slag powder using in roadbed replacement were proposed by orthogonal experiments, and the effects on compressive strength of FCB of amount of cementitious materials, dosage of slag powder and water binder ratio were studied when the water binder ratio is in the range of 0. 5-0. 6, further the drying shrinkage and frost resistance of FCB were studied. The results show that the ratio of cement, slag powder, foaming agent and water is 1∶0. 54∶0. 03∶0. 85 is the initial mixture ratio of FCB with slag powder. The effect order on the compressive strength of FCB is amount of cementitious materials, dosage of slag powder, water binder ratio, with the water binder ratio increases at each age, the dry shrinkage rate first increases,and then decreases, finally increases again, the smallest is of the water binder ratio is 0. 55, and after freezing and thawing cycles, the compressive strength loss rate increases and then decreases, the smallest is of the water binder ratio is 0. 6, with the dosage of slag powder increases at each age, dry shrinkage rate first decreases and then increases, the smallest is of the dosage of slag powder is 35%, and after freezing and thawing cycles, the compressive strength loss rate increases gradually, the smallest is of the dosage of slag powder is 15%.关键词
