Calculate cross sectional area of 10mm bar amd 8mm bar, then divide them and you will get the no. of bars.
For Eg. - Area of 10mm bar = 78.53 sq.mm
Area of 8mm bar = 50.26 sq.mm
No. of 8mm bars in replacement for 10mm bar = 1.562 bars [ theoritical]
In practical u'll provide 2-8mm bars.
A 10mm steel bar can be changed into an 8mm steel bar by stretching it or pushing it through a resizing die. This will reduce the overall diameter of the bar without a need to completely reform it.
TMT steel bars are produce from Carbon steel material(BILLETs/,INGOTS)Finish steel bar coming out of finishing stage of rolling mill is passed through devise where it is being passed through high pressure water jets to give the steel bars desire quality's 500/550Kg per cms.squre
Steel and iron, particularly in the form of TMT (Thermo-Mechanically Treated) steel bars, play a pivotal role in reinforcing concrete structures. Here's why steel is the material of choice for this critical task: High Tensile Strength: Steel boasts an exceptional tensile strength, which means it can withstand pulling forces without easily breaking or deforming. Concrete, on the other hand, is excellent in compression but weaker in tension. By embedding steel within concrete, you harness the superior tensile strength of steel to counteract the tensile stresses that concrete alone can't handle. Ductility: Steel is also highly ductile, which can deform without breaking. This ductility allows it to absorb and distribute stress effectively, preventing sudden, catastrophic failures in concrete structures. When concrete begins to crack under stress, the embedded steel maintains structural integrity. Corrosion Resistance: TMT steel bars, specifically designed for construction, are further treated to enhance corrosion resistance. This feature ensures the longevity and durability of the reinforced concrete, especially in harsh environmental conditions. Size and Shape Variability: Steel reinforcement can be customized for various project requirements. Different-diameter steel bars can be used to provide the necessary strength and support for specific structures. Using steel, especially TMT steel bars, in reinforcing concrete is an intelligent engineering choice. It addresses concrete shortcomings regarding tensile strength, provides flexibility for structural integrity, and ensures the longevity of the reinforced concrete. For all your steel needs, including TMT steel bars, consider Vedanta Metalbazaar. Their commitment to quality and reliability makes them a trusted source for steel and iron products in the industry.
This is an incorrect approach. The current method is the reason for the steel wastage. The steel saving is left to the hands of Bar Benders and site engineers.A scientifically proven system, to save steel in the construction projects is the need of the hour.Steel saving starts with the Rebar Detailed engineering. This is also called as Rebar Detailing. A professional Rebar Placing drawing and an optimized Bar Bending schedule (BBS) are the targeted output of the Rebar detailing.
It all depends on the type and sizes of the steel used. It also depends on the load that the concrete has to take at certain points. 7865kg is the weight of a cubic meter of steel. Typical examples; A pile cap could contain 400kg/m3 A heavy duty industrial slab or structure could contain 200kg-400kg/m3 A footpath could contain 40kg/m3 (all depends on the design, but numbers above should give you a rough answer)
The answer is 3.854 if you work out the total meterage then multiply by 3.854 that will give you total tonage I am a steel fixing subcontractor so this sum becomes second nature hope this has been of some help
give me formula for weight in kg 8mm 10mm 12mm 16mm
The RFM of steel varies dependent upon the levels of differing impurities which give each specific type of steel its desired properties. You need to be more specific in you question. Which type of steel?
imagin this 10mm X 10mm X 10mm will give you a cm3 then 100cm X 100 cm X 100 cm will give you a m3 There are 1M cm3 in a m3 and add the zeros form mm (3) so 1,000,000 plus 000 = 1,000,000,000mm3 1m3 = 1,000,000,000 mm3 hope this helped!!

your guy gave you another chance because he loves you and trusts you good enough to give you another chance.
My pot is made out off stainless steel. steel is a metal! there is a sentence that has the word steel in it

question is,are you willing to give that chance?
