外文摘要：The water permeability and compressive strength are the main mechanical properties of non-fine concrete. In this paper, the researches on the variation of the compressive strength and permeability coefficient are conducted from the aspects of types of aggregate, ratio of aggregate to cement and the aggregate size. Data analysis show that, compared with pebble coarse aggregate, non-fine concrete made from gravel coarse aggregate has better water permeability but lower compressive strength. With the increasing ratio of coarse aggregate to cement, the compressive strength and water permeability of non-fine concrete can be improved that firstly increase and then decrease. The aggregate size increases, the compressive strength of pervious will decrease while the permeability coefficient increases. The compressive strength and water permeability of non-fine concrete cannot simultaneously achieve the best value, and both of them are in the opposite direction change of each other. ? 2014 ejge.
