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. You may also like.
In practical terms, the number itself isn't all that meaningful, but it becomes useful to use in comparison with other woods. For instance, Ipe is known to have excellent strength properties among imported species, and has a crushing strength of 13,510 lb f /in 2 (93.1 MPa). In comparison, White Oak is a well-known wood used in cabinetry and furniture, …
The crushing value of aggregates is a numerical index of their strength, and it is used in the construction of roads and pavements. A lower crushing value is preferable for roads and pavements as it indicates a lower crushed fraction under load, resulting in a longer service life and greater economic efficiency.
