Abstract：The influence of silica fume amount,aggregate size and aggregate-binder ratio on compression strength,porosity and permeability coefficient were studied,so that the optimum proportion of pervious concrete has been confirmed.The results showed that,the pervious concrete which contain 5～10 mm aggregate has the optimal compression strength;the compression strength is the highest when silica fume amount is 15％,and compared with control group the 7 d,28 d compression strength increased by 32.3％,27.7％ respectively,but the porosity continuously decreased with the increasing of silica fume amount;with the aggregate-binder ratio increases from 2.6 to 3.8,the compression strength decreased continuously,and the porosity and permeability coefficient increased gradually.
