Title Slide Portland Cement Association

Concrete is very strong in compression, but relatively weak in tension. The tensile capacity of concrete is only about one tenth of its compressive strength. Consider the beam shown here. Load applied at the center of the beam produces compression in the top of the beam, and tension in the bottom at midspan. Unreinforced, plain concrete, beams can fail suddenly upon cracking, with little warning. Why Use .
