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/㎠, the splitting tensile strength was 15∼25 kgf/㎠, the flexural strength was 36∼54 kgf/㎠, and the coefficient permeability was 1.05 ×10-¹ ∼ 9.20 ×10-² cm/sec. In order to change the maximum size of aggregate, It is believed that other mixtures should be studied further.
