Temperature Impact on Engineered Cementitious Composite Containing Basalt Fibers

Engineered cementitious composite (ECC) is a new generation of fiber-reinforced concrete with high ductility and exceptional crack control capabilities. However, ECC can suffer substantial reduction in when exposed to elevated temperatures resulting loss crack-bridging ability. In this study, the effect adding basalt fiber (BF), which an inorganic high-temperature resistance for production ECC, was studied. Moreover, change mechanical properties including compressive, tensile, flexural strength, experimentally investigated under up 400 °C. The results showed that addition BF reinforced improved tensile strength effectively, but compressive marginally decreased. A significant decrease observed range from 300 °C, while it increased smoothly heated diminished after slight strain gained 100 This work paves way future investigations focusing on development ECC.
