Fire resistance and thermal performance of hybrid fibre-reinforced magnesium oxychloride cement-based composites

Magnesium oxychloride cement (MOC) is recognized as an eco-friendly alternative to Ordinary Portland Cement (OPC) with inherent fire resistance. However, its thermal and mechanical performance under fire and the underlying fire resistance mechanisms have not been well understood. This study examines the fire resistance and thermal performance of hybrid polyethylene (PE) and basalt fibre (BF) reinforced MOC-based composite (HFMOC) modified with ground granulated blast furnace slag (GGBFS) and metakaolin (MK), which was designed and developed to enhance the fire resistance capacity of HFMOC especially for non-structural application such as cladding. The compressive and tensile strength tests were conducted at…
