Study on physical performance of lightweight foam concrete using oyster shells according to unit cement content

굴 패각을 사용한 경량기포 콘크리트의 단위시멘트량에 따른 물리적 성능에 관한 연구

Research for heat insulation of buildings is being carried out, in which a heat exchange barrier is used around the openings and balcony parts as a method for heat exchange blocks. However, the preparation for a fire is inadequate. In order to improve the EPS used as a heat exchange barrier in an attempt to solve this, there is a study on lightweight foamed concrete, but as the amount of EPS used for strengthening fire resistance increases, it becomes lower. There is no strength applied to buildings, and also. There is a limit to the amount of EPS used. In the study, we use oyster shells to secure the EPS replacement rate limit of lightweight Foamed concrete, and try to measure the change of physical properties depending on the unit cement content.
