At present, LCW is relatively extensive in the fields of seismic resistance and impact resistance, but it is relatively lacking in fire resistance performance, so the fire resistance performance of LCW under fire action will be the focus of research, this paper reviews the different composition structures of LCW and its wallboard characteristics, as well as the experimental research progress of LCW in recent years, including impermeability, bending test, thermal insulation performance, etc., and mainly summarizes its fire resistance performance. This review will play a positive role in exploring the key technologies of innovative composite wallboards in the field of construction in the future, and clarifying the future research directions.展开更多
