Abstract: This paper describes the possibility of the utilization of recycled aggregate and by-product aggregate to the porous concrete (POC). In this experiment, two kinds of recycled aggregates and a by-product slag aggregate were used; namely, recycled aggregate produced by crushing concrete made in laboratory, another recycled aggregate produced by crushing field-demolished concrete, and electric arc furnace oxidizing slag aggregate, which is produced as a by-product from the steel-making process. This experiment investigated how aggregate kind and void content of POC influence the strength, static modulus of elasticity, permeability of POC and coexistence of POC with plants. This study indicated that the continuous voids approximated 98% of the total ones, and the total voids were 20-30%. These voids influenced the properties and application of POC. The strength of POC was inversely proportional to the void quantity. And also the strength of POC using recycle aggregate adhered to coarse aggregate a large amount of mortar was low. In this case, to improve aggregate was necessary. The growth of the plants (Kentucky bluegrass and White clover) was possible by filling the void of POC in the fertilizer. The growth was about 8cm in height after two months. In the observation of the cross section of POC, the root of the plants grew to 55cm depth in the inside of the POC in two months.
