basalt mressive strength. The rock hardness of basalt is 6 on the Mohs scale, and can be seen through a combination of its compressive strength: 100-300 Mpa (Megapascal), its tensile strength: 10-30 Mpa, and its shear strength: 20-60 Mpa, which denotes that depending on the mineral makeup, basalt rocks fall in the strong – very strong category.

From the analysis results, it can be found that the effect of basalt fiber on the compressive strength of RPC is limited, and the high content of basalt fiber even reduces the strength of RPC obviously. This is because the basalt fiber mainly improves the tensile stress and crack resistance of concrete, solves the fragile tensile response of ...
