Rebar has been placed atop a temporary wooden formwork deck prior to pouring concrete. The large horizontal rebar "cages" will be encased within a beam, while several thick vertical rebar stubs will stick out of the pour to form the base of a future column. Concrete is a material that is very strong in compression, but relatively weak in tension.
Rebar detailing is the discipline of preparing 'shop/placing' or 'fabrication' drawings or shop drawings of steel reinforcement for construction. Engineers prepare 'design drawings' that develop required strengths by applying rebar size, spacing, location, and lap of steel .
A Johnson bar (also Johnson corrugated bar) is a type of corrugated high-carbon steel [1] rebar used to reinforce concrete.. The Johnson bar was invented by A.L. Johnson [2] of the St. Louis Expanded Metal Company.
Initiation and propagation periods of steel rebar corrosion in a reinforced concrete structure (Tutti diagram). [2] [3] Initially, the chemical reactions that normally occur in the cement paste, generate an alkaline environment, bringing the solution in the cement paste pores to pH values around 13. In these conditions, passivation of steel ...
Bar, a long piece with a rectangular cross section, but not so wide so as to be called a sheet. Rod, a round or square section long compared to its width; see also rebar and dowel. Plate, metal sheets thicker than 6 mm or 1 ⁄ 4 in. Open web steel joist

Rebar. Rebar is a steel bar or mesh of steel wires used in reinforced concrete and masonry structures to strengthen and hold the concrete in tension. The surface of rebar is often patterned to improve the quality of the bond with the concrete. Rebar is necessary to add tensile strength, while concrete is strong in compression. It can support ...
