폐발포폴리스티렌 단열재를 순환골재로 사용한 경량 단열 모르타르의 강도특성

Strength Characteristics of Light-weight Insulating Mortar Using Wasted Foam Polystyrene heat Insulating Materials as Recycling Aggregate

The replacement ratio of waste EPS was varied, and its effect on compressive strength and absorption capacity was investigated. According to the experimental results, The 28th day compressive strengths for the W/C 50% specimens were 17.5~21.2MPa, which was relatively low compared to the 13.6~22.2MPa of the W/C 70%.
