Why We Test Concrete Compressive Strength after 28 Days

When its strength have reached 99 in 28 days still concrete continues to gain strength after that period but that rate of gain in compressive strength is very less compared to that in 28 days. After 14 days of casting concrete concrete gains only 9 in next 14 days. So rate of gain of strength decreases.
