99%. As you can see the concrete gains its strength rapidly til 7th 14th Days. Then gradually increases from there. 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.

What is the difference between crushing strength and

Concrete serves us well here since the characteristic strength of concrete is the parameter widely used to analyze and define the strength For a cube of concrete, the compressive strength would be the resistance of that particular cube (or sample) to compressive load. It is measured by applying a certain compressive load and noting the load it can take before failure. Characteristic strength of concrete would also give us the compressive strength of a particuar mix of concrete.
