TMT Bars provide strength in Reinforced Cement Concrete and makes every structure long lasting.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What is RCC Construction?<\/strong><\/h2>\n\n\n\n<p>Francois\nCoignet, a French industrialist built a four storey house in Paris with\nreinforced cement concrete in 1853. That was first ever attempting to build\nusing reinforced cement concrete in modern history. Since then, the technology\nhas evolved with one of the highest buildings in the world being built using\nRCC. <\/p>\n\n\n\n<p>Reinforced Cement Concrete is a composite material with excellent strength and durability. Like clay, concrete can be moulded into any shape, on any scale by using suitable moulds or formworks. One can make concrete anywhere by mixing its components in suitable proportion. It slowly develops strength over a period of time, which helps in smooth onsite operations. This portable nature of concrete along with the strength it develops is the key to its popularity.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Introduction of TMT rebar in RCC Construction<\/strong><\/h3>\n\n\n\n<p>Concrete on\nits own has got excellent strength when pressed against anything. However on pulling\n(or stretching) it easily gives way. <\/p>\n\n\n\n<p>While\nconcrete has been used as a construction material since Roman times, the use of\nreinforcement in the form of iron was only introduced in the 1850\u2019s by Coignet,\nand it was not until the 1880\u2019s that a German civil engineer G. A. Wayss used\nsteel as reinforcement.<\/p>\n\n\n\n<p>Steel round\nthat has prominent grips are forcibly inserted in concrete to give desired strength.\nBeauty of steel rebar is that they can take both extensible as well as\ncompressive loads. In RCC columns you would find steel rebars carrying bulk of compressive\nloads. Steel &amp; concrete have got similar temperature coefficients, making\nthem expand\/contract together and helping the bonding.<\/p>\n\n\n\n<p>The\nintroduction of Thermo Mechanically treated (TMT) steel bar has brought a new\nera in India\u2019s construction industry. Round plain steel ruled over this\nindustry up to sixties. TOR steel took over in the seventies and maintained its\nsupremacy till nineties. 1997 Onwards the industry has seen extensive use of <a href=\"https:\/\/shyamsteel.com\/tmt-bar-facts\/\">TMT steel bar<\/a> that are\ncorrosion-resistant, thereby ensuring longer life for RCC structures. TMT bars\nare widely used in general concrete reinforcement structures, bridges and\nflyovers, dams, thermal and hydel power plants, industrial structures,\nhigh-rise buildings, underground platforms in metro railway and rapid transport\nsystem.<\/p>\n\n\n\n<p>TMT is an\nacronym for \u201cthermo-mechanical treatment\u201d. Thermo Mechanically Treated (TMT)\nbars are manufactured using the Quenching &amp; Tempering (Q &amp; T)\ntechnology. A TMT bar gets its strength properties from quenching and\ntempering. No mechanical treatment is involved in TMT Bars.<\/p>\n\n\n\n<p>In TMT bars,\nthe carbon content can be restricted to 0.25% to attain weld-ability and at the\nsame time no strength is lost on this account. The joints can be welded by\nordinary electrodes and no extra precautions are required. Another advantage of\nTMT bars is their tough surface providing high yield strength and a soft core\nproviding excellent ductility. Strength, weldability and ductility are the\nproperties which make TMT steel highly economical and safe. An additional advantage\nof TMT steel is that a twisting operation is included in Tor steel, which\nsubjects the bars to torsional stresses making them less corrosion resistant\nwhile TMT bars are free of such stresses. As a result TMT bars have excellent\ncorrosion resistance power. There are ample of TMT Bar Manufacturers in the\nmarket but it is always required to buy <a href=\"https:\/\/shyamsteel.com\/iso-certified-tmt-rebar\/\">ISO Certified TMT Bars<\/a>\nthat has the perfect combination of Strength &amp; Flexibility.<\/p>\n\n\n\n<p>The TMT process gives the bar superior strength and anti-corrosive properties. Controlled water-cooling prevents the formation of harsh carbides, which is the main reason behind the corrosive nature of common bars. Due to very high elongation values and consistent properties throughout the length of bar, TMT rebars have excellent bendability. The soft ferrite pearlite core enables the bar to bear dynamic and seismic loading. TMT bars have high fatigue resistance to dynamic \/ seismic loads due to its higher ductility. This makes them most suitable for use in earthquake prone areas and very cost effective.<\/p>\n\n\n\n<p><u>QUANTITY OF STEEL USED IN RCC CONSTRUCTION<\/u><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>FOR RCC SLAB: 1.0% OF CONCRETE VOLUME<\/li><\/ul>\n\n\n\n<ul class=\"wp-block-list\"><li>FOR RCCBEAM: 2.0% OF CONCRETE VOLUME<\/li><\/ul>\n\n\n\n<ul class=\"wp-block-list\"><li>FOR RCC COLUMN: 2.5% OF CONCRETE VOLUME<\/li><\/ul>\n\n\n\n<ul class=\"wp-block-list\"><li>FOR RCC ROAD: 0.6% OF CONCRETE VOLUME<\/li><\/ul>\n\n\n\n<p><u>CONSTRUCTION COST and REBAR COST PER SQ.

Reinforcement is generally placed in areas of the concrete that are likely to be subjected to tension, such as the lower portion of beams. It is usual for there to be a minimum of 50 mm cover, both above and below the steel reinforcement, to resist spalling and corrosion which can lead to structural instability<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Checklist\u00a0for\u00a0Steel\u00a0Reinforcement<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\"><li>Should be free of loose rust, oil paints, mud, dust, etc<\/li><\/ul>\n\n\n\n<ul class=\"wp-block-list\"><li>Should be stacked above the ground level free from any water accumulation<\/li><\/ul>\n\n\n\n<ul class=\"wp-block-list\"><li>Should be cut, bent (preferably by cutting &amp; bending machines) and fixed properly by using right size of binding wires at required intervals<\/li><\/ul>\n\n\n\n<ul class=\"wp-block-list\"><li>Should be fixed in a position by use of cover blocks (if it is concrete cover block then grade of concrete should be the same or higher), chairs, spacers, additional supporting bars, and laps; laps to be used in proper location as advised by Engineer-in-charge.<\/li><\/ul>\n\n\n\n<ul class=\"wp-block-list\"><li>Should be placed and tied in such a manner that concrete pouring is done without any kind of segregation and compaction is done by an immersion vibrator of right size as per the requirement<\/li><\/ul>\n\n\n\n<p>It is always\nimportant to buy from Best Quality TMT Bar Manufacturers.
