摘要
The influence of aggregate to cement ratio(A/C), sand to aggregate ratio(S/A) and water to cement ratio(W/C) on mechanical properties and pervious coefficient of pervious concrete prepared by recycled aggregate were systematically investigated in the paper. The optimum mix proportion by weight of pervious concrete prepared by recycled aggregate were 3.5 of aggregate to cement ratio, 0.15 of sand to aggregate ratio and 0.34 of water to cement ratio, resulted from an effect coefficient method. Flexural strength and compressive strength of pervious concrete road brick prepared by recycled aggregate concrete could satisfy the requirements of Chinese Standard for Concrete Road Brick (JC/T466-2000) and had good pervious performance.
