A Study on the Development of Water-Permeable Concretes for Overlay
오버레이용 투수성 콘크리트의 개발에 관한 연구
Abstract
The purpose of this study is no examine the combination effect on strength preperties of water-permeable concretes mixed with redispersible polymer, silica fume and polypropylene fibers for overlay in pavement. The water-permeable concrete with a water-cement ration of 25%, polymer-cement ratios of 0 to 10%, silica fume contents of 0 to 10% and polypropylene fiver contents of 0 to 1.5% are prepared, and tested for flexural strength, compressive strength and water permeability. It is concluded concretes are obtained at a polypropylene fiber content of 1.0% and a silica fume content of 10% with a void filling ratio of 50%. And the water-permeable concretes with a flexural strength of 14.1~28.0kgf/
