The compressive strength test of concrete is an essential procedure that helps engineers and construction professionals evaluate the strength and durability of concrete structures. The test is commonly done on concrete cubes, using a compressive testing machine to determine the maximum compression load the cube can withstand before failing.
Building materials, especially low-quality concrete, are believed to be a source of building collapses. One way to determine the quality of concrete is by testing its compressive strength, also known as Concrete Compressive Strength. The compressive strength of concrete depends on the components used in the mixing process.
