Compressive Strength of Cement Concrete
After that crushing is done in the usual way. The cube can be tested after 3, 7, 14 and 28 days. Cube is placed in compression testing machine and axial load is applied at the rate of 140 kg/ cm2. In actual concrete is required sufficient time to gain strength. Usually 28 days strength is considered as the full strength of concrete.

Compressive Strength of Concrete & Concrete Cubes | What
As per Indian code definition. “The compressive strength of concrete is given in terms of the characteristic compressive strength of 150 mm size cubes tested at 28 days (fck). The characteristic strength is defined as the strength of the concrete below which not more than 5% of the test results are expected to fall.”.

How to Calculate Rate of Loading for Concrete Cube Testing in
Cube size is 10 cm x 10 cm x 10 cm. So total load on this surface area will be. 1.373 x 10 x 10 = 137.3 Kn. So rate of loading will be = 137.3 / 60 = 2.88 Kn/Sec. Same way you can calculate rate of loading for each cube size you test at your laboratory.

Compressive Strength of Concrete – Cube Test, Purpose
The testing machine must be accurate, well-calibrated, and having capacity adequate enough to crush the concrete cube. Do not exceed 90% of the capacity of the machine while testing. If the cube does not crush, cut off the machine and use a machine of higher capacity. It is necessary to use a certified and tested proving ring.
