Rebar Requirements in Concrete Wall Construction | Hunker
Reinforced steel is manufactured as bars (rebar) or welded wire mesh. The deformations in rebar bond to concrete, and the strong bond enables loads to be transferred between the two materials. When steel makes contact with concrete, a nonreactive film develops on the surface of the rebar that helps protect it .

GROUTING CONCRETE MASONRY WALLS NCMA
Openended units allow the units to be placed around reinforcing bars. This eliminates the need to thread units over the top of the reinforcing bar. Horizontal reinforcement in concrete masonry walls can be accommodated either by sawcutting webs out of a standard unit or by using bond beam units.
Reinforcement PCA
Reinforcing Bars. In order to enhance bond, reinforcing bars are produced with deformations, as shown here, to provide mechanical bond between the bars and the concrete. To uniquely identify the reinforcement, reinforcing bars are marked during production with a letter and number signifying the type and grade of steel.

Rebar Wikipedia
Rebar (short for reinforcing bar), known when massed as reinforcing steel or reinforcement steel, is a steel bar or mesh of steel wires used as a tension device in reinforced concrete and reinforced masonry structures to strengthen and aid the concrete under tension. Concrete is strong under compression, but has weak tensile significantly increases the tensile strength of the ...
Excess Steel Reinforcement: Problems and Remedies
Reinforcement is generally put into concrete to cater for its relative weakness in tension compared with compression. The term 'crosssectional area' (CSA) is used to refer to the area of the section under consideration, both for the concrete and for the steel. The ratio of the area of the steel to that of the concrete is the percentage of reinforcement, which for concrete
Fabrication of Reinforcement
bar or coil. Generally reinforcing bar is supplied to the fabricator from the mill in bundles of straight lengths. Stock lengths are normally 12m, 14m and 15m, and can be up to 18m. Nonstandard lengths can also be supplied, usually subject to a minimum tonnage requirement. Bar is fabricated by cutting on shear lines, and subsequently by bending
