Experimental Study on the Strength of Basalt Fiber Confined Concrete under Impact Loading

Abstract:

With the cylindrical concrete specimens of C30, C40 and C50 strength grades confined by basalt fiber-reinforced polymer, the strengths of confined concrete specimens at the strain rate of 100/s~200/s are obtained in test of impact by Φ100 mm SHPB based on quasi-static loading test. Analysis shows that the quasi-static strength ratio of basalt fiber confined concrete have a good linear relationship with restraint ratio. Under impact loading, the strengths of confined specimens increase with the increase of strain-rate. They are more sensitive to strain-rate than the plain specimens. The strain-rate effect is strengthened with the increase of basalt fiber layers, but it tends to decrease when the fiber is increased to three layers.
