Rebar Properties - CRSI: Concrete Reinforcing Steel Institute

Steel reinforcing bars are produced from molten steel, by forming it into large rectangular billets and then running it through a series of dies, which shape the steel into reinforcing bars. During the forming process, deformations are formed in the surface of the bars that are used to help in transferring loads between the concrete and the reinforcing steel.

ISO 15630: Testing the tensile strength of concrete-reinforcing steel

The 3-point flexure test as well as the rebend test are used to determine the bending ability of concrete-reinforcing steel. During the flexure test to EN ISO 15630-1, the concrete-reinforcing steel is bent at a predetermined angle (usually 90°).The diameter of the upper anvil and the anvils, and the distance between the anvils are usually specified in the product standard and
