Compressive Strength of Concrete: Definition, Cube Test
What is Compressive Strength of Concrete? Compressive strength is a paramount property of concrete that measures its ability to withstand loads that would reduce the material's size. Defined technically, it is the maximum load per unit area that concrete can bear without undergoing a significant change in shape.
