Basalt Rock Properties and Uses ScienceStruck. The rock hardness of basalt is 6 on the Mohs scale, and can be seen through a combination of its compressive strength: 100300 Mpa (Megapascal), its tensile strength: 1030 Mpa, and its shear strength: 2060 Mpa, which denotes that depending on the mineral makeup, basalt rocks fall in the strong very strong category.

Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0). Lithology is commonly derived during log analysis, so m may be estimated (Table 1). What is needed still is an initial measure of rock strength provided by C 0.

Intact rock strength . The uniaxial compressive strength of a rock material constitutes the highest strength limit of the rock mass of which it forms a part. It is determined in accordance with the standard laboratory procedures. For the purpose of rock mass classification, the use of the well known point load strength index can be useful as the

Feb 17, 2016The compressive strength of concrete increases with increasing basalt fibre content up to %: after this, the concrete compressive strength tends to decrease gradually by 12%. This is due to the cohesive decrease between the cement paste and the aggregate that plays a significant role in the compressive strength of concrete.
