Construction Concerns: Concrete Reinforcing Steel

2020-12-11  Some modern rebar is nonmetallic and made of fiber- or glass-reinforced plastic. These are highly corrosion resistant and used where the reinforced concrete will be submerged in water or exposed to salt (which is corrosive) as it is in bridges, piers, seawalls, and breakwaters. These are also frequently used in the Middle East, where fresh water, sand, and gravel often contain salt. Fiber reinforced plastic rebar often has higher tensile strength and less stiffness when compared to carbon steel. It also has less fire resistance and requires deeper embedment in concrete to provide the same level of fire
