Table 1: Recordings during Compressive Test on Cement . 6. calculation; The measured compressive strength of the cubes shall be calculated by dividing the maximum load applied to the cubes during the test by the cross sectional area, calculated from the mean dimensions of the section and shall be expressed to the nearest 0.5 N/mm 2.
The Crushing strength or compressive strength is given by the formula as: C= P/A. Where, C = compressive strength. P = Load at failure. A = cross sectional area of bearing face of the specimen. Then the average value of the six specimens is calculated and the result is recorded for that stone sample.
A top load test essentially involves applying a downwards compression to measure resistance to crushing of a product, usually a container. Test methods define the speed of compression and extent of deformation, and peak force measurement determines the product sample strength. An appropriate universal tester will also be able to measure ...
increaing compressive load until failure to find the crushing strength in kg/cm2 However, this test is seldom carried out due to difficulty in preparing specimens and not getting reproducible results. On the contrary, the aggregate crushing test is simple, rapid and gives fairly consistent results. Applications of Aggregate Crushing Test
Crushing Strength Test: For conducting this test, specimen of size 40 × 40 × 40 mm is build from parent stone. Then finely the sides are dressed and placed in water for three days. The saturated specimen is provided having a layer of plaster of Paris on its bottom and top surfaces to get even surface so that load applied is uniformly distributed.
The test measures the resistance of the edges to crushing since it is the corners and edges of the boxes that are mostly responsible for bearing the loads. Therefore, performing it means knowing the strength of the factor that contributes the most to a boxs resistance. This test can be performed using specific, in house machinery, or ...
