  • Evaluation Of Crushing Stress At Critical State Of

    Sep 04 2014 A series of triaxial compression tests was performed on three types of granulated coal ash GCA to investigate their shear and crushing behaviour. The experimental results show that GCA displays different dilatancy characteristics to other natural granular materials due to excessive breakage even at low stresses.

  • Compressive Or Crushing Strength

    Ordinarily where the length of the test specimen is not greater than four diameters and the ends are squarely faced See Fig. 7. the force acts uniformly over each square inch of area and the crushing strength is equal to the maximum load P divided by the area of the cross-section A.
