An Experimental Study on Mechanical Properties of Basalt Fiber Reinforced Concrete

As a new environment-friendly fiber material, the basalt fiber has been used in engineering construction to a certain extent. Through the tests for compressive strength and split tensile strength of concrete matrices in different ages, the reinforcement of basalt fiber for concrete was explored in this paper. As shown by the test results, the mixture with basalt fiber would efficiently enhance the ductility of the concrete being broken, and improve the compressive strength and split tensile strength of concrete matrices in different ages, in which the compressive strength of concrete in the age of 3d and the split tensile strength of concrete in the age of 28d were improved more significantly, by 9% and 19% respectively. The test analysis results can be used as a reference for application of basalt fiber in concrete projects.
