There has been for a number of reasons growing interest in the use of porous concrete. Recently, it is used as an ecological(environmentally friendly concrete). Porous concrete allows water and air to permeate freely through its continuous voids. For the same cement factor, its strengths are considerably Sower than that of conventional concrete. So, this study was carried out to develop its strengths by using glass fiber. In the result of the study are as follows, 1) Its strengths were the highest at glass fiber/cement ratio 3%(mass), but were decreased at 4%. 2) It was possible to conclude the compressive strength by the non-destruction test, such as ultra-sonic pulse velocity and D.M of elasticity, and to conclude the void ratio by the unit weight. 3) In the experiment, porous concrete which coefficient of permeability was 0.4∼0.7㎝/s and compressive strength is 200∼300㎏f/㎠ could manufactured.
