“…The microstructural evolution and mechanical properties of ECC exposed to elevated temperatures were investigated in this study. To further improve the sustainability and hightemperature/fire resistance of ECC for wider engineering applications, the high-cost PVA fibres can be replaced by recycled fibres (e.g., recycled tyre polymer fibres) [87], and inorganic fibres with a higher melting point (e.g., steel fibres) can be incorporated [88], which is the subject of ongoing research and will be presented in future publications.…”
