Experimental Study on Compressive Property of Basalt Fiber Reactive Powder Concrete
Keyword(s):
In order to study the stress-strain relationship of basalt fiber reactive powder concrete (RPC), the compressive stress-strain curve test of four groups of basalt fiber RPC was carried out. The test parameters including two kinds of basalt fiber length and three fiber volume fractions showed that the deformability of the test piece was improved and the failure process was delayed after incorporating basalt fiber. The optimum fiber fraction of the test piece with 12 mm long fiber was 0.10%. According to the experimental data, the stress-strain of the basalt fiber RPC was drawn. For the curve, the constitutive relation is fitted by the piecewise equation, and compared with the experimental curve, the fitting result is better.
