기포제를 사용한 구조용 경량 모르타르의 역학적 특성에 관한 실험적 연구

Abstract

The objective of this study is determining the mechanical property of light and strong preformed lightweight foamed mortar using the mineral foam agent. Also the lightweight foamed mortar has superior property of insulation and light-weight because it has many inner pore in the structure. So, the lightweight foamed mortar used to construction field where need property of insulation. Experiment was done to examine mechanical and insulation properties of the specimen according to the variation of density. As the result of the experimental research, thermal insulation property of light-weight foamed concrete is superior than ordinary portland mortar. Moreover, it is known that the mortar has enough strength for structural member when foaming agent proportion is 0.4∼0.5%.
