compressive strength of granite

<br>Modulus of rupture test – application of the load at a mid-point. A higher compressive strength between1,800 psi (12.45 MPa) and 19,000 psi (131 MPa) means the stone can endure an upper crushing load. The deformation properties of the intact rock, classically expressed in terms of Young’s modulus and Poisson’s ratio, can be obtained from the results of uniaxial and triaxial

Compressive strength of rocks PetroWiki

Jun 04, 2015· 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. C 0 can be estimated from porosity or sonic velocities, but

Natural stone strength (compression, bending, and abrasion

Jul 20, 2018· Compressive strength test. This test is vital for evaluating the stone’s resistance to crushing loads. A wall stone has to bear the compressive load of the stone’s weight. A stone floor has to withstand loads of people and heavy objects. So, compressive strength is the highest load per unit area borne by the stone without giving in.

Dynamic uniaxial compression tests on a granite — Monash

Dynamic uniaxial compression tests for the Bukit Timah granite in Singapore were conducted at four loading rates (10 0, 10 1, 10 3 and 10 5 MPa/s). It was found that the compressive strength increases from 205 MPa to 235 MPa with loading rate increasing from 10 0 to 10 5 MPa/s. Evidence also indicates that there are small changes in the Young's modulus and the Poisson's ratio of the granite
