Abstract
Porous concrete has good permeability sine it contains about 10∼20 % of voids, had has been introduced to korea in early 1980's. It, however, has problems such as a lack of optimized mixture, low strength and durability, and etc. It is thus Interesting to manufacture high-performance porous concrete satisfying the mechanical characteristics to be supplied In practical construction. The results of this study were as follows : the compressive strength was 132∼221 kgf/$\textrm{cm}^2$, the splitting tensile strength was 15∼25 kgf/$\textrm{cm}^2$, the flexural strength was 36∼54 kgf/$\textrm{cm}^2$, and the coefficient permeability was 1.05${\times}$10$\^$-1/ ∼ 9.20${\times}$10$\^$-2/ cm/sec. In order to change the maximum size of aggregate, It is believed that other mixtures should be studied further.
