Why We Test Concrete Compressive Strength .
Why do we test concrete compressive strength after 28 days? Concrete gains strength with time after casting. It takes much time for concrete to gain 100% strength and the time for same is still unknown. The rate of gain of concrete compressive strength in higher during the first 28 days of casting and then it slows down.
