This is because the concrete is assumed to be fully cracked by the tensile stress. 4,000 psi compressive strength concrete will crack at about 400 psi tension, but to strain with a rebar tension of 24,000 psi; the concrete would have to develop 3,000 psi in tension.
Compressive strength test on bricks are carried out to determine the load carrying capacity of bricks under compression. This test is carried out with the help of compression testing machine. Bricks are generally used for construction of load bearing masonry walls, columns and footings. These load .

The objective of compressive-strength testing of concrete cylinders is to determine the amount of force it takes to break a cylinder of concrete. A test cylinder is placed in a compression-testing machine, and a constant load is applied to the cylinder until it breaks. The compressive strength .
5.1 Care must be exercised in the interpretation of the significance of compressive strength determinations by this test method since strength is not a fundamental or intrinsic property of concrete made from given materials. Values obtained will depend on the size and shape of the specimen, batching, mixing procedures, the methods of sampling, molding, and fabrication and the age, .
