Abstract

Poor fire resistance of fibre-reinforced polymer (FRP) restricts its further application in construction structures. In this paper, a novel fibre-reinforced cementitious matrix confined concrete column (FRCMCC) using fireproof grout as the fibre matrix was developed, and experiments were conducted to establish its performance and analyse the mechanical properties under axial compression. The test results show that its failure mode was more moderate compared to the traditional fibre-reinforced resinous matrix confined concrete column (FRRMCC), and the concrete columns confined with multi-layer fibres and end reinforcement could provide both good strength and ductility.
