compressive strength of rocks

How to Calculate Compressive Strength | Sciencing Compressive strength of a material is the point at which the material fails. Calculating compressive strength involves testing to find this failure point and using the data from the test to feed the calculation. Estimating the Intact Rock Strength of a Rock Mass . intact rock strength by different means on the same rock masses. The results show that in many cases an estimation of intact rock strength by 'simple means' is more representative for establishing the intact rock strength of a rock mass than establishing the intact rock strength by more elaborate testing. INFLUENCE OF INTACT ROCK STRENGTH ON . first intact rock sample was assigned a uniaxial compressive strength of 205 MPa and an elastic modulus of 104 GPa with the UCS and elastic modulus values of the other samples downgraded by 10% until the    Read More
