A Study on Bending, Compressive Strength of Mortar According to Temperature and Heating Time Change using Oyster Shell as Aggregate

굴 패각을 골재로 사용한 모르타르의 온도별 가열 시간에 따른 휨·압축 강도에 관한 연구

As the building is becomes bigger and larger, it can lead to big damage in case of fire. Also, tunnel, machine room and underground joint are spaces that can cause high temperature fire above 1,350℃ in case of fire. Therefore, a refractory material is need that can be withstand in high temperatures for long time. One side, the composition of oyster shell is CaCO₃ of 90% or more. It is expected that it will be possible to use it as a high calcium natural material which is the material of the refractory board. According to, Study on bending, compressive strength of mortar according to temperature and heating time change using oyster shell as aggregate the most commonly occurring particle sizes form 2.5mm to 5mm.
