Abstract
Porous concrete enables water and air to pass through a firmly hardened material and allows required nutrients to reach roots of plants. The purpose of this study is to analyze void ratio, strength property and planting ability when using silica fume and fly ash, the change of aggregate gradation and ratio of paste to aggregate. The results of an experiment from the planting ability of the porous concrete to its influence on the compressive strength are reported in this paper. As a result of the experiment, the compressive strength is higher when the gradation of aggregate is smaller, and it also goes higher when the ratio of paste to aggregate gets larger. The planting ability of porous concrete is decided by the germination and the grass length of perennial ryegrass. The grass length of perennial ryegrass is longer when the gradation of aggregate is greater and the ratio of paste to aggregate gets smaller. Therefore the efficiency of planting goes through the perennial ryegrass is in compliance with the void ratio, aggregate gradation.
