What is the difference b/w compressive strength .

Compressive strength is the load (measured in pounds/sq. in. or /sq.ft.) which the concrete (poured over a solid base) will support, without damage. Specifically, by being crushed. If the load gets large enough, the concrete will fracture and be c...

Cube tests and the uniaxial compressive strength .

The cube is undoubtedly the most convenient specimen to use when large numbers of crushing tests are required for concrete control purposes. The cylinder, or prism, on the other hand can give a much better estimate of the uniaxial compressive strength of concrete. The recent tendency has been to favour the adoption of the cylinder as the standard specimen, despite its shortcomings regarding ...

The extent of environmental impacts of mining depends greatly on mine design [13]. One of the impacts is stability of the ground surface [14, 15]. Ground stability has an indirect influence on the water movement in a min-ing area [16]. In case of surface ...

THE UNIAXIAL COMPRESSIVE STRENGTH OF SOFT ROCK

Influence of L/D Ratio The ISRM [1] recommended an L/D ratio of at least 2.5:1 for compression tests. However, a sufficient number of specimens with this ratio are often difficult to obtain [13]. With L/D ratios of 1.6:1 to 2.5:1, no significant indication has been found that the UCS is influenced by the L/D ratio. 0.00 2.00 4.00 6.00 8.00

Comparison of UCS to Bond Work Indices

UCS is more resistive to breakage by compression; but crushing is the mechanism of breaking rocks by compression. It is counterintuitive for a rock with a high UCS to have a low crushing Work Index. Therefore this result is considered unreliable and use of UCS to estimate Wi C is not recommended for this mine. 0 5 10 15 20 25 30 35 40 0 50 100 ...
