crushing strength test on aggregates

Crushing Strength Test of Stone. For conducting this test, a specimen of size 40 × 40 × 40 mm is prepared from parent stone. Afterward, the sides are finely dressed and placed in water for three days. The saturated specimen is provided with a layer of plaster of paris on its top also bottom surfaces to get even surface so that load applied is distributed uniformly.
