| Abstract: | Basalt fiber, as a kind of new inorganic fiber, compared with carbon fiber, aramid fiber and glass fiber, has many unique advantages. In recent years, basalt fiber becomes more and more popular among the material fields because of its comprehensive performance and low cost. Geopolymer is a new type of high-performance cementitious material which is different from ordinary Portland cement. It can be used instead of metal, ceramic and cement in application to aerospace, civil engineering, foundry, decoration and other fields. This research has studied the durability performance of basalt fiber roving in alkali solutions with different concentrations, temperatures and durations and the bond behavior of the interface between the basalt fiber roving/textile and the geopolymer matrix. Test results indicated that the impact of high temperature on the damage and degradation of basalt fibers is of more significance than that of alkaline solutions. In addition, higher concentration leads to larger strength reduction and mass loss of basalt fibers. Furthermore, surface treatment using epoxy resin can improve significantly the bond performance of basalt fibers in the geopolymer matrix. |
