What is a concrete cube test? A concrete cube test is a way to test the strength of concrete. The concrete is cast into cube moulds and allowed to cure. It is then crushed at intervals of 7 or 28 days. This test is used to determine whether concrete that has been poured at a construction site has the specified compressive strength.
So we can't predict the strength until the concrete comes to that stable state. Once it attains certain strength at 7 days, then we know (according to the table) only 9% of strength going to increase. So at sites, we do normally test concrete at this interval. If the concrete fails at 14 days, then we will reject that batching.
One of the methods of checking its fit for purpose is to carry out a concrete cube test which measures the compressible cube strength of the concrete and relates directly to the required design strength specified by the …
