Development of Lightweight Polymer Concrete Using Synthetic Lightweight Aggregate and Application for Bottom Draining Structure

인공경량골재를 활용한 경량 폴리머 콘크리트의 개발 및 바닥배수구조물에의 적용

This study was performed to develop the lightweight polymer concrete using expanded clay and perlite to improve workability, durability and chemical resistance for bottom draining structure under severe condition. This paper was composed of two parts. One is to invest the physical and mechanical properties of lightweight polymer concrete using synthetic lightweight aggregate, the other is to the develop products for bottom draining structure. Physical and mechanical test for lightweight polymer concrete was performed unit weight, compressive and flexural strength, chemical resistance, accelerated weathering test, absorption ratio and optimum mix for lightweight polymer concrete was designed. Also, products for bottom draining structures by optimum mix of lightweight polymer concrete was made draining trench of small size.
