what is the compressive strength of concrete block

Concrete Block Vs. | Hunker

According to the Masonry Advisory Council, all concrete blocks must have a minimum compressive strength of 1900 pounds per square inch. Many dense blocks are stronger than this. According to Mechanical Properties of Unreinforced Masonry, the average concrete block can withstand 3500 psi, while the average clay can withstand 3000 psi.

Compressive Strength of Concrete Cubes Civilology

According to Wikipedia, Compressive Strength of concrete is defined as the Characteristic strength of 150mm size concrete cubes tested at 28 days. Concrete is a macro content with Sand, Cement, Coarse aggregate as its microingredient (Mix Ratio) and gains its 100% strength over time at the hardened state. Take a look at the below table.
