Crushing Test Or Compression Strength Test On Stone
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.

Specifically, with regards to footings that you might use for a deck or house support piers (but not as a footing for the foundation necessarily).8. STRENGTH OF SOILS AND ROCKS,material is compressed between the platens of a testing machine as illustrated in Fig. 8.1. The compressive strength is then defined as the maximum load applied to crush the specimen divided by the cross-sectional area.
