Compressive Strength of Concrete Cubes – Lab Test & Procedure Overall Strength of a structure such as flexural resistance and abrasion directly depends upon the compressive strength of concrete. According to Wikipedia, Compressive Strength of concrete is defined as the Characteristic strength of 150mm size concrete cubes tested at 28 days.

As the time required to test the concrete cubes at 140 kg/cm2/min is high, it is not followed on site. As concrete grades ranging from M20 to M40 are usually used, they were selected for the project. It is also observed that the time taken to test a cube is 20 seconds to 1 min which generates the rate of loading as 900 kg/cm2/min to 1400 kg/cm2 ...

Basically, the force supplied by a concrete compression machine is a definite value. For normal concrete strength application, say below 50MPa, the stress produced by a 150mmx150mmx150mm cube is sufficient for the machine to crush the concrete sample. However, if the designed concrete strength is 100MPa, under the same force (about 2,000kN) supplied by the []

Compression Test of the Concrete Specimen is most widely used test to measure its compressive strength. Two types of concrete specimen: Cubes & Cylinders are used for this purpose: Cubes of size 150mm are more common in Asia, Russia & European countries while Cylinders of 150mm in diameter & 300mm high are common in U.S and Australia.

As per IS Code, the sample selection for the concrete cube test has listed below. The minimum value of Compressive Strength for a cube. As per IS 456, the individual compressive value of a concrete cube should not be less than 75% of its grade. Example – If the concrete grade is M20, then the individual crushing
