In order to explore the application of nanomaterials in fiber concrete, in this research, the effect of nanomaterials SiO2 on the basalt fiber concrete was studied with experimental analysis methods. The variation values of mechanical properties were calculated respectively. On this basis, the influences of silicon dioxide nanometer and basalt fibers on the mechanical properties of nanosilica silicon dioxide nanometer basalt fiber concrete were studied. Different contents of silicon dioxide nanometer were added to concrete, different contents of basalt fibers were added to concrete, and both were added to concrete. The results showed that adding silicon dioxide nanometer could modify building concrete and significantly improve the mechanical properties of concrete. the increase of silicon dioxide nanometer content of nanomaterials, the strength of concrete showed a trend of first rising and then falling. When silicon dioxide nanometer content was 1.2%, the mechanical strength was the largest. As the contents of basalt fiber increase, concrete strength showed a trend of first increasing and then decreasing. When basalt fiber content was 3kg/m3, it was the optimal content and the concrete strength was the largest. And the mechanical properties of the concrete mixed with silicon dioxide nanometer and basalt fibers were significantly improved.
