Rebars are used for reinforcing concrete and making it stronger and more reliable. While concrete is very good at withstanding compression (being pushed together), it doesn’t handle tension (being pulled apart) well on its own. Rebars, or reinforcing bars, are placed inside the concrete to help it resist tension and bending forces. This added strength prevents cracks and structural failure, ensuring that buildings, bridges, foundations, and other concrete structures stay safe and last longer.
Rebars are used in a wide range of construction applications — from residential homes to large-scale industrial and infrastructure projects. The correct placement, size, and bending of rebars are essential for the structure’s overall stability and performance. That’s why rebar detailing is so important. Silicon Engineering Consultants offers rebar detailing services that provide accurate, practical drawings showing how rebars should be arranged within a structure. These detailed plans help reduce errors during construction, save time, and improve safety on-site.
In summary, rebars are used for strengthening concrete so it can handle both compression and tension, playing a vital role in the durability of concrete structures.
To prevent injury.
Waist slab is used in case of stairs. The rebars are bent at some angles on which steps are built.

There is no constant value for the ratio of the rebars and concrete volume. The rebars depends on the structural designer's safety factor and the factors affecting the framing like wind, earthquake and soil.
The unit weight of rebars is typically around 7.85 kg/m³. In a reinforced concrete mix with a compressive strength of 60 MPa, the amount of reinforcement steel used is usually between 1-2% of the total volume of concrete. Therefore, the weight of rebars per cubic meter of reinforced concrete at 60 MPa would be approximately 78.5 kg/m³ to 157 kg/m³.

Rajuri Thermex TMT500 rebars have excellent bend properties due to the unique ductility (elongation values) obtained when using the German HSE Thermex Technology.Corrosion Resistance propertiesControlled water-cooling prevents the formation of coarse carbides, which has been cited as the main cause for the corrosive nature of common bar.Another reason for better corrosion resistance is the absence of surface stresses caused by the cold twisting (and Torsteel) process.WeldabilityRajuri Thermex TMT500 rebars with carbon content less than 0.25% can be used for butt and other weld joints without reduction in strength at the weld joints.Fire ResistanceUnlike Torsteel and CTD Rebars, Thermex bars have high thermal stability. They are the preferred choice when elevated temperatures of 400-600 C may be encountered (Chimneys, fires).Earthquake ResistanceThermex rebars have high fatigue resistance to Dynamic/ Seismic loads due to its higher ductility quality. This makes Thermex bars most suitable for use in earthquake prone areas.FormabilityDue to very high elongation values and consistent properties through out the length of bar, Thermex rebars have excellent workability and bendability.Strain AgeingDue to unique and scientific manufacturing process and chemical composition, Thermex rebars show no tendency of embrittlement either during welding or cold deformation of welded joints.Cost EffectiveThermex TMT rebars required 15-20% less usage than CTD bars for same work with cost 5% more than than CTD bars. This results in overall saving of 10-25%.
The placement of steel reinforcing is dependent on the requirements of the strength and load-bearing of the concrete. A structural engineer should be contacted in this regard.
