Properties of Water- Permeable Concrete Using Recycled Aggregate

재생골재를 이용한 투수콘크리트의 특성

The effects of polymer-cement ratio and recycled aggregate content on the continuous void ratio, coefficient of permeablity, compressvie, tensile and flexural strengths of water-permeable polymer-modified concretes using recycled aggregate are examined. As a result, the continuous void ratio and coefficient of permeablity of the water-permeable polymer-modified concretes tend to decrease with increasing polymer-binder ratio. Regardless of the recycled aggregate content, the compressvie, tensile and flexural strengths of the water-permeable polymer-modified concretes wtend to increase with increasing polymer-cement ratio.
