摘　　要：透水混凝土是一种新型的建筑材料,国内对它的研究还不成熟,尤其是将其用于道路上还处于起步阶段。由于具有孔隙率大的特点,造成强度大大降低。针对这一问题,通过大量的试验,寻求满足轻型交通要求的配合比,并设计不同的目标孔隙率,来研究它的透水性能和吸声性能。研究表明该混凝土不论从强度方面,还是从透水方面都可以应用到轻型车道的路面上,进而可以提高地下水位、减轻城市排水设施的负担和降低汽车在路面上行驶时产生的噪音,从而说明研究该透水混凝土的必要性。Porous concrete is a kind of new building material, and the domestic researching is not mature, especially in pavement engineering. The concrete strength will be cut down because of its large porosity.A kind of suitable mix ratio is found to meet light transportation demands. At the same time, different target hole rate is designed in order to research its penetrative and absorbing ability.The studies indicate that the porous concrete is suitable to light transportation in strength and penetrative ability.Then ground water level is increased,burden of drainage system is lightened and traffic noise that the driving automobiles produce on the road will be cut down.These explain that the porous concrete studied is necessary.

关 键 词：孔隙率 抗压强度 抗折强度 透水系数 吸声系数
