How much steel is RCC slab? For RCC Beam & Column need 2-3% steel, say 2.5% steel. RCC slab volume can be found by multiplying the thickness with the area of the slab. Now generally we consider the amount of steel in any concrete member is 2% of the concrete volume. So subtracting the steel amount one can easily find the concrete volume.
How much steel does RCC slab use? Thumb rule for Steel required for RCC slab is 80 kgs/m3, then quantity of steel required for 100 sq ft ( 1.416 m3) rcc slab is equal to = 80 × 1.416 = 113.3 Kgs. Ans. :- 113.3 Kgs steel quantity are required for 100 sq ft 6 inch thick rcc roof slab.

How do you calculate percentage of steel in RCC? Calculate the percentage of reinforcement with the formula P = 8.33UA/t, where P is the percentage and t is the thickness. For example, the percentage of reinforcement of a 30-inch slab with two layers of No. 6 rebar spaced 4 inches on center is P = 8.33_6_0. 43/30 = 0.72 percent.

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.
How do you calculate 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.
What is the ratio of RCC?
Generally 1:2:4 and 1:1.5: 3 ratios of RCC are used in construction work. Where cement concrete 1:2:4 is used; it means 1 part of cement 2 parts of fine aggregate/coarse sand and 4 parts of coarse aggregate. This ratio of cement concrete gives high strength of cement concrete and is recommended for following works.

How do you calculate kg of steel?
If we put 1 meter length for each diameter of steel bar in the formula then we will get the unit weight.
6 mm ø bar = 6² x 1/162 = 0.222 kg/m.
8 mm ø bar = 8² x 1/162 = 0.395 kg/m.
10mm ø bar = 10² x 1/162 = 0.617 kg/m.
12mm ø bar = 12² x 1/162 = 0.888 kg/m.
16mm ø bar = 16² x 1/162 = 1.580 kg/m.
