reinforcing steel milled from scrap metals. Their physical and chemical properties were examined and found that the characteristic tensile strength is too high with very little elongation leading to limited ductility compared with standard mild and high yield steel. Ndiaye et al (2002) working in the
Assessment of Mechanical Properties of Reinforcing Steel Reinforcing steel for construction works are specified in terms of their yield strength, ultimate tensile strength, percentage elongation. By assessing these properties, it is ensured that their use in construction works meet relevant code specifications. Some works on mechanical properties of steel rods produced in Nigeria has been done.
Reinforcing steel plays a key role as a construction material whose properties must be known to the users before application in either design or construction purposes. BS4449:1969,1997, 2005 and many other codes have specified limits on the properties of reinforcing steel and
Lecture 11. Reinforcing steel and composite materials11.2 Reinforcing steel Reinforcing steel could be used as conventional or pre-stressed reinforcing, depending on the design situation. In conventional reinforcing, the stresses fluctuate with loads on the structure. This does not place any special requirements on the steel. On the other hand, in pre-stressed reinforcement, the steel is under continuous tension. Any
Properties of Reinforced Concrete Steel Rebars Exposed to
AbstractIntroductionExperimental StudyTest Results and EvaluationsConclusionsAs described in the previous studies, steelstructural members loose strength under elevated temperatures. In this study, themechanical properties of steel rebars were investigated which exposed to hightemperatures and cooled to room temperature. According to test results, themost common reinforcing steel rebar S420 showed a brittle fracture mechanismunder elevated temperatures. Splitting yield strength, tensile strength,elongation, and toughness values were low for S220 steel. These resultsMechanical Properties of Reinforcing and Prestressing For temperatures up to 600°C, the tested reinforcing steel showed no major alterations. However, for temperatures above 700°C, important changes in the steel properties could be observed. For the prestressing steel, those alterations began at 400°C.
Generally, Grade 430 reinforcing steel has higher carbon, manganese and silicon contents than Grade 300 and is micro-alloyed with 0.04% vanadium. Chemical analysis of Grade 300 samples shows a mean vanadium content of 0.0027%. As vanadium is not deliberately added in

reinforced concrete Definition, Properties, Advantages The reinforcing steelrods, bars, or meshabsorbs the tensile, shear, and sometimes the compressive stresses in a concrete structure. Plain concrete does not easily withstand tensile and shear stresses caused by wind, earthquakes, vibrations, and other forces and Properties of Reinforcing Steels - AEC Onlinecontent of reinforcing steels to 0.012%, in order to restrict strain ageing. The only exception to this is for micro-alloyed steels, where nitrogen is combined with vanadium for strengthening. In the combined form, nitrogen does not have a strain ageing effect.
