- Abstract
Effects of fly ash and silica fume on the strength development of basalt fiber reinforced cement mortar strength were investigated. Influences of combined addition of fly ash and silica fume on the corrosion resistance of basalt fiber in the cement mortar were studied. The results show that the early flexural strength of cement-based material increases with the addition of the basalt fiber, while the late reinforcing effect reduces and even becomes adverse causing the cement matrix strength to decrease. The reduction of the late flexural strength of cement-based material was significantly increased with the addition of fly ash and silica fume. The studies on XRD spectrum and microstructure morphology demonstrate that the contents of Ca(OH)2 crystal and basalt fiber corrosion degree are decreased, the interfacial properties between basalt fiber and cement matrix is changed with the addition of fly ash and silica fume.
