Concrete has relatively high compressive strength, but significantly lower tensile strength.As a result, [further explanation needed] without compensating, concrete would almost always fail from tensile stresses – even when loaded in compression. The practical impliion of this is that concrete elements subjected to tensile stresses must be reinforced with materials that are strong in
