Properties of concrete - Wikipedia

Reinforced concrete. Concrete has relatively high compressive strength, but significantly lower tensile strength.As a result, without compensating, concrete would almost always fail from tensile stresses (Stress (mechanics)#Mohr's circle) even when loaded in compression.The practical implication of this is that concrete elements subjected to tensile stresses must be reinforced with materials ...
