### Properties of concrete

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