An Experimental Study on the Performance Evaluation of Lightweight Foamed Concrete According to Size and Replacing Ratio of Artificial Lightweight Aggregate

인공경량골재 크기 및 혼입량에 따른 경량기포콘크리트의 물리적 성능 평가에 관한 실험적 연구

This study investigated the properties of lightweight foamed concrete by using synthetic foaming agent and artificial lightweight aggregate. The effects of artificial lightweight sizes on the compressive strength, density and pore structure of the concrete were investigated. The samples were assessed by MIP analysis and simultaneous SEM was used to study their pore distribution. This study showed the improvement of important properties of lightweight foamed concrete. Lower pore distribution and correspondingly higher compressive strength values were reached. This is for the purpose of providing basic data for the use of lightweight foamed concrete through improvement on the problem such as unstability, falling in fluidity and the strength of existed foaming agent.
