Steel is only used as rebar because elongation of steel due to high temperatures (thermal expansion coefficient) nearly equals to that of concrete. Grades of […] Steel reinforcement bars or rebars are used to improve the tensile strength of the concrete, since concrete is very weak in tension, but is strong in compression.
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 strength.Rebar significantly increases the tensile

In Kenya, high tensile steel for the reinforcement of concrete mainly comes in the form of cold-twisted square bars. However, hot-formed deformed bars are steadily gaining ground in this field, and this issue addresses this changing trend. This edition of the standard also aims at making the steel bars easily traceable to the manufacturers, thus
For reinforcement mesh products, grade B500A steel is typically used, and for rebar, B500B is used. B500C steel is seldom requested and it would always be worth checking with a structural engineer whether grade B500B could be used instead of B500C, since B500C typically has a

Plain round mild steel bars BS 785: 1938 & BS 785: Part 1, 1967 36,000 psi for bars up to 1 ½ inches . BS 4449: 1969, 1978 & 1988 250 N/mm 2. Cold worked deformed bars BS 1144: 1943
Reinforcing steel BS EN 13670 Execution of structures BS EN 10138 Prestressing Compared to normal strength steel, high strength steel has lower bridges to facilitate construction and crane structures. Studies show that the ratio of the tensile residual stress to yield stress of the member seems to decrease with increasing yield strength
Reinforcing steel used in road structures must have yield and ultimate tensile strength as specified later. This chapter covers the dimensions of reinforcing bars, tensile strength and bending procedure. 11.1.2 Terminology 11.1.2.1 Definitions (1) Deformed bar. Steel bar with protrusions; a bar that is intended for use as
BS EN 10080, “Steel for the reinforcement of concrete- Weldable reinforcing steel- General”, was published in 2005. Under the rules of CEN, the British Standards for reinforcing steel were to be either withdrawn or amended. As BS EN 10080 did not include any steel grades or a method of readily differentiating between grades, BS4449 was

12mm REBAR HIGH TENSILE MILD STEEL REINFORCING BAR. Reinforcing bar, AKA Rebar is used to help concrete stand tension force, although the concrete is strong enough by nature to withstand compression force, it can also crack from load bending tensile force, and therefore it need help resisting the tensile stress using high tensile substance.
Where steel reinforcement of a slab is required for structural reasons, the specification will more than likely require high-tensile steel bars as well as fabric mesh, and the design should be undertaken by a qualified engineer. Steel mesh comes in a wide array of profiles with varying mesh sizes and wire sizes as indicated in the table below.
