Properties of Concrete Blocks — Strength

In the use of concrete blocks for the walls of buildings, the stress to which they are subjected is almost entirely one of compression. In compressive strength well-made concrete does not differ greatly from ordinary building stone. It is difficult to find reliable records of tests of sand and gravel concrete, 1 to 4 and 1 to 5, such as is used in making blocks; the following figures show ...

According to the Code this would require a block compressive strength of 1900 psi. Recently on projects, some designers are now specifying a higher f’m, i.e., 2000 psi, 2500 psi and 3000 psi with Type S mortar. According to the Code this would require a block compressive strength of 2800 psi, 3750 psi and 4800 psi, respectively.

Compressive Strength of Concrete and Concrete Testing ...

Concrete cube testing or cylinder testing is done to check the development of the strength of the concrete. In other words, we test the concrete to check whether it has reached or developed beyond the characteristic strength of concrete assume in the design. Based on the test results, conformity can be checked as per the relevant standards.

Compressive strength - Wikipedia

Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to Tensile strength which withstands loads tending to elongate. In other words, compressive strength resists being pushed together, whereas tensile strength resists tension (being pulled apart). In the study of strength of materials, tensile strength ...
