In order to understand the acid and alkali resistance performance of basalt fiber, tests are done to study the quality change and monofilament strength under the situation of 80℃, 2 mol/L hydrochloric acid and sodium hydroxide solution corrosion, and comparison is done for the polypropylene fiber, alkali glass fiber acid-proof alkaline. The results show that for the acid performance, basalt fiber is the optimal, followed by polypropylene fiber, alkali glass fiber. For the alkali resistance performance, quality performance in the consequence of polypropylene fiber, basalt fiber and alkali glass fiber. Test results provide the reference for basalt fiber and new materials in the popularization and application of cement concrete.
