Which type of reinforcement bars are used in RCC?
In RCC (Reinforced Concrete Structure) TMT Bars are commonly used for its superior tensile strength. The Ribs on TMT Bars provide superior bonding in Cement Concrete. Best quality TMT Bars has a tensile strength of 64000 psi (PSI – Strength of Concrete is measured in pounds per square inch).
Why do we use TMT bars?
Cost-effective– TMT bars have higher tensile strength and better elongation value, which basically means you need less steel for the same amount of construction. Apart from reducing the cost of raw material, this also saves cost on transportation and storage.
Which steel is best for RCC?
TMT Steel or TMX steel is the best bet for house construction. They are the latest generation of reinforcement steel (high-strength and ductile than their predecessors) .
Why steel bars used in RCC are round in shape?
Stress concentration is always more when you use anything which having corners , e.g.as circular column is more efficient than rectangular column but due to form work costing its not in the regular practice. In circular shape the stress distribution is uniform.
What is the price of TMT bars?
₹ 57,000 – 58,000 / Ton.
Where is TMT bars used?
TMT bars are widely used in general purpose concrete reinforcement structures, bridges and flyovers, dams, thermal and hydel power plants, industrial structures, high-rise buildings, underground platforms in metro railway and rapid transport system.
Why bar is used for construction?
It will provide enough strength to structure. It is embedded in concrete fibre to resist the structure load. Steel bar provided in slab beam and column for house construction. Reinforcing steel bars are used to help concrete withstand tension forces.
Which TMT bar is better?
Top 10 best TMT bars brand in India are – 1) Tata tmt bar grade Fe500, 2) Tata tiscon SD TMT bar, 3) Jindal Panther TMT bar, 4) Sail TMT bar, 5) Kamdhenu TMT bar, 6) SAIL and ViZag CRM TMT bar, 7) Tata TMT bar, 8) SRMB steel tmt bar, 9) JSW steel tmt, 10) Shyam Steel tmt bar, etc.
What is Fe415 and Fe500?
The explanation behind is Fe 415 signifies that power of 415 N/sq.mm is required to deform the TMT bar, whereas Fe-500 denotes that a force of 500 N/sq.mm is required to deform the TMT bar. The difference in the strength/quality between Fe 415 and Fe 500 grades, therefore, is 20\%.
What is the expansion of TMT?
TMT: Thermo Mechanically Treated or TMT bars are high-strength reinforcement bars having a hardened outer core and a soft inner core. They are manufactured under a process called Thermo Mechanical Treatment, after which they are named.
What is the use of TMT bars in RCC construction?
TMT Bar adds strength to the RCC. Various elements of RCC constructions are slabs, beams, foundation etc. It is always recommended to maintain the accurate ratio as per the type of construction.
What is the thickness of an RCC slab?
However in general the thickness of RCC slab should be 4.5” thick. MS Steel for slab for main bar should be 10mm and for distribution 8mm or 10 mm. For beam it should be 16mm and 12 mm as per span. The thickness has to be at least 4.5-5.0″.
What are the components of RCC?
Various elements of RCC constructions are slabs, beams, foundation etc. It is always recommended to maintain the accurate ratio as per the type of construction. TMT Bar is the main component in RCC that gives the tensile strength to your home.
Why TMT bars are used in cement concrete?
Therefore TMT Bars are used in Cement Concrete to increase the tensile strength. Without using TMT Bars no structure can withstand during an earthquake. TMT Steel Bars/Reinforced Bars are highly ductile and for its tensile strength it can hold the building during an earthquake.
