摘要
为了确定混凝土的透水系数、最佳抗压强度和抗折强度及相应水灰比,提升透水混凝土的整体性能,使用体积法,在一定孔隙率下,4组混凝土水灰比分别为0.25、0.30、0.35和0.40,经过试验得到相应的力学强度,绘制相关曲线关系。实验结果表明,透水混凝土的整体性能由孔隙率和水灰比共同决定。得出在施工中应根据实际要求的抗折强度、抗压强度和透水系数,从而选定最佳水灰比。
To improve the overall performance of pervious concrete,the effect of water-cement ratio on the permeation coefficient,compressive strength and flexural strength was studied.The overall performance of pervious concrete with water-cement ratio of 0.25,0.3,0.35 and 0.4 was tested.It was found that the best water-cement ratio should be determined according to the requirement of compressive strength,flexural strength and permeability coefficient.
