Fire Resistance Performance of Fiber Reinforced Geopolymer Concrete: Review

Abstract

Geopolymer is a relatively new substance that has sparked a surge of research into nearly
every field of geopolymers in recent years. It's still on the verge of becoming a competitive OPC
concrete alternative. Mechanical, hardness, and fire resistance properties of geopolymer are
exceptional. There has been no/limited research on the effect of fiber integration on fire resistance of
geopolymer concrete. In fire-exposed concrete, fiber can help to resist spalling. The goal of this study
is to develop materials that exhibit eco-friendly properties and better fire-resistant behavior.
Moreover, the combined effect of binder materials and different fibers on the fire resistance of
geopolymer concretes. According to the findings, the fire resistance of fiber-reinforced geopolymer
concretes increased in the order of carbon fiber-based GPC, micro-steel fiber-based GPC, hooked
steel fiber-based GPC, and polypropylene fiber-based GPC. Furthermore, as compared to slag and
metakaolin-based GPC, fly ash-based GPC has greater stability and fire resistance. Fiber-reinforced
GPC can also be used as a sustainable and durable building material in various construction
applications where high performance is needed.
