Which steel is used in RCC work?
TMT Steel Bars/Reinforced Bars are highly ductile and for its tensile strength it can hold the building during an earthquake.
For different concrete grades different quantity of the materials are required.
TMT Bar adds strength to the RCC.
Various elements of RCC constructions are slabs, beams, foundation etc..
Which grade steel is best for construction?
More commonly, steel bars of grades Fe 415 and Fe 500 are used for construction purposes. The number of the grade indicates the yield stress. Fe 415 graded steel is being used mostly nowadays among the two.
Which cement is best for RCC slab?
There is three types of cement available in market or ordinary Portland cement (OPC) Portland slag cement (PSC) and portland pozzolana cement (PPC). OPC 53 and PPC ( Portland pozzolana cement) of all brand are the best cement for rcc roof slab construction in india,bihar and jharkhand.
Which grade of cement is best?
Which is the best cement for house construction?Ordinary Portland Cement (OPC) 43 Grade Cement: It is used majorly for wall plastering works, Non-RCC structures, pathways etc. … Ordinary Portland Cement (OPC), 53 Grade Cement: … Portland Pozzolana Cement (PPC): … Portland Slag Cement (PSC): … White Cement:
How many kg of steel is required in 1m3 of concrete?
Minimum quantity of steel required for 1m3 concrete slab is 1%, now 1% of 1m3 = 0.01 m3, and we know that 1m3 steel weight is 7850 Kg, so weight of 0.01m3 steel = 0.01 × 7850 = 78.50 kg, so minimum quantity of steel required for 1m3 concrete slab is 78.50 Kg.
What is RCC made of?
Its full name is reinforced cement concrete, or RCC. RCC is concrete that contains steel bars, called reinforcement bars, or rebars. This combination works very well, as concrete is very strong in compression, easy to produce at site, and inexpensive, and steel is very very strong in tension.
Which is better fe500 and Fe500D?
While both Fe500 and Fe500D TMT bars are the best TMT bars for construction projects, the Fe500D TMT bars certainly comes with a greater ductile strength than the Fe500 TMT bars. The Tensile strength of steel remains the same for both these products. However, it is the overall ductility that makes all the difference.
What are the different grades of steel?
Steel is graded as a way of classification and is often categorized into four groups—Carbon, Alloy, Stainless, and Tool. Carbon Steels only contain trace amounts of elements besides carbon and iron.
What is the ratio of RCC?

Which type of steel is used in construction?
Carbon SteelPlain Carbon Steel or Mild Steel This is the most common type of steel used in building construction, which is also known as mild steel. It is incalculably strong and durable, and ensures a sturdy built.
How do you calculate the weight of steel?
STEEL QUANTITY:Weight of bar in kg/meter should be calculated as (d2 ÷ 162) where’d’ is the diameter of bar in mm.’L’ for column main steel in footing should be considered as minimum 30cm/as specified.For bent up bar add 0.42d in straight length of bar where’d’ is the clear depth of beam/slab.More items…
Why steel is used in RCC?
It is because the two materials bond together very well with no slippage and thus act together as one unit in resisting the applied loads, apart from few other important properties of steel. The tensile strength of steel is approximately equal to 100 – 140 times the tensile strength of plain concrete mix.

Which TMT bar is better?
TMT Bars with Lower Grades have Low Strength and High Flexibility and the ones with Higher Grades have High Strength and Low Flexibility. Fe 500 is considered as the best grade of TMT Bars which can be chosen for all types of construction purposes as it offers the perfect balance of strength and flexibility.

What grade of steel is a36?
Chemical Composition A36 is a low carbon steel. Low carbon steels are classified by having less than 0.3% carbon by weight. This allows A36 steel to be easily machined, welded, and formed, making it extremely useful as a general-purpose steel.
