Effect Of Compressive Strength In Concrete

That tensile strength is the basis for its ability to resist bending, or its flexural strength. ACI 207R, Effect of Restraint, Volume Change, and Reinforcement on Cracking of Mass Concrete, states in Chapter 3 that concretes tensile strength is often taken as 6.7 times the square root of its compressive strength. It also notes that where a ...
