Compressive Strength of Concrete Cubes

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.

COMPRESSIVE STRENGTH TEST OF CONCRETE .

Compressive strength is calculate using the following formula. Compressive strength (kg/cm 2) = W f / A p. Where. W f = Maximum applied load just before load, (kg) A p = Plan area of cube mould, (mm 2) Safety Precautions. Use hand gloves, safety shoes apron at the time of test. After test switch off the machine.
