What is Compressive Strength

The compressive strength of concrete is often tested to evaluate if the actual concrete mix meets the requirements of the design a small sample of concrete mix is first cast in a cube or cylinder form and allowed to age for 28 days For concrete samples that contain additional material a longer curing time of 56 days is recommended If the design engineer wants to test an existing
