    Properties Of 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 – 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 tension often
