Date: 9/1/1988. Abstract: Develops a methodology for the determination of the crushing strength of reinforced concrete membranes with two-way orthogonal reinforcement on the basis of theoretical considerations and experimental results. It differs from previous work in this area with respect to two principal features.

The crushing or compressive strength of normal building bricks should not be below 3.5 N/mm². The bricks of high quality should not have strength below 14 N/mm². The compressive strength test is also known as the crushing strength test which is an important type of laboratory test conducted on bricks to determine the load-carrying capacity of bricks when subjected to a compressive load.

The compressive strength of the concrete cube test provides an idea about all the characteristics of concrete. By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures.

Crushing Strength. Sometimes known as compression strength parallel to the grain, this is a measurement of the wood’s maximum crushing strength when weight is applied to the ends of the wood (compression is parallel to the grain). This number is a good indicator of the wood’s strength in applications such as deck posts, chair legs, or other

For normal concrete and HSC, the concrete compressive strength test results from cube specimens are generally higher than cylinders specimens [6]. As states in BS 1881, the compressive strength of concrete gained by cylinder specimens is equal to 0.8 times of the compressive strength gained by cube specimens.
