Porous concrete is expected as an environmental preservation-type concrete but causes concern about its low freeze-thaw resistance compared with that of normal concrete. The purpose of this study is to clarify the effect of silica fume and fine fibers, a new material, on the freeze-thaw resistance of porous concrete. This study also included a vegetation experiment on porous concretes of the same kinds to observe the growth of plants. As a result, the freeze-thaw resistance of porous concrete was significantly improved when10-30% silica fume and 1Vol% fibers were used, with large differences in the state of deterioration and number of cracks being observed between normal porous concrete and fiber reinforced porous concrete containing silica fume. The growth of plants on fiber reinforced porous concrete was found to be comparable to that on normal porous concrete.
