It is safe to say that the compressive strength of concrete is the most important parameter used in the design of concrete structures; however, concrete does not provide significant tensile strength. Perhaps, this is the very fundamental idea of building reinforced concrete, where steel reinforcement provide the much needed tensile strength of the section.
