Abstract:

The basalt fiber, a new inorganic fiber material, can significantly improve the mechanical properties of concrete. In combination with the previous research results, the mix proportion design, compressive strength, flexural strength, tensile strength, frost resistance, dry-shrinkage performance and durability were studied through a series of experiments by changing the mixing amount of basalt fiber. Meanwhile, the influence of different basalt fiber preparation technology on concrete material performance was also discussed. The research results can provide theoretical basis for the engineering application of basalt fiber reinforced concrete.

Key words: mechanical property, mixing amount, preparation technology, basalt fiber
