How much quantity of steel required for 1m3 concrete
How much quantity of steel required for 1m3 concrete
STEEL REQUIRED FOR 1 CUM OF CONCRETE
Steel required for 1 cum concrete depends on following factors
1)Framed or Load Bearing structure
2) Utility of Structures
3) Diameter of rod
4) Size height of column & length of beam
5) Foundation types (based on Soil investigation)
Thumb Rule for 1 cum of concrete Kg/m3
1)rcc slab is 80 kg/cubic meter of wet volume of concrete
2) beam is 120 kg/cubic meter of wet volume of concrete
3)column is 160 kg/cubic meter of wet volume of concrete
4) footing is 40 kg/cubic meter of wet volume of concrete
5) rcc structure is 100- 120 kg/cubic meter of all calculated wet volume of concrete.
6) steel in rcc structure is 3.5 Kg to 4 kg/ sq ft of built up area.
Quantity of steel in concrete depending on type of structure and load of structure.
1. FOUNDATION
For Foundation :- 0.5 to 0.8 % steel are required
Let us take minimum 0.5 % of steel is required on 1 m3 concrete
Then quantity of steel. = (0.5/100)×1× 7850 =39.25 kg
If we take maximum 0.8% steel is required
Then quantity of steel is = (0.8/100)× 7850 = 62.8 kg
2. COLUMN
For column :- 0.8 – 6 % of steel required
For minimum 0.8 %. = (0.8/100)×7850 = 62.8 kg
For maximum 6% = (6/100)× 7850 = 471 kg
3.COLUMN
For Beam :- 1- 2 %
For minimum 1% = (1/100) ×7850 = 78.5 kg
For maximum 2 % = (2/100) × 7850 = 157 kg
4. SLAB & LINTEL
Slab and lintel :- 0.7 – 1.0 %
For minimum :- (0.7/100)× 7850= 54.95 kg
For maximum 1% :- (1/100)× 7850 = 78.5 kg
Overall we assume Average 2.5 % of steel required in 1 m3 concrete work
Then = (2.5/100) × 1 ×7850 = 196.25 kg Approx 200 kg steel
1m3 = 200 kg steel
1m3 = 2 Quintal steel required
