calculate the volume of slab that is L*b*h get whole answer
in cum as a thumbrule 80-100kgs per cum metre is the
quantity of steel taken for slabs either take their average
and multiply by slab(in cum)to get in kgs

Answer / sai sreekanth

generally we use to calculate steel by by taking its diameter at ends we use higher diameter of steel and then taking its length and numbers and weight can be measured by using d^2/162
suppose 8 is the diameter then weight is 64/162 is 0.39 and length is 10M and number is 2 so 20m*o.39 is 7800mm^3..

Answer / biswajit sinha

Approx,
1.5 to 2% steel in columns,
1 to 1.5% in beams ,
0.7 to 1% in slabs and
0.5 to 0.8% in footings.
(%age of Conccrete.)
if concrete is 100 cum in Column.
than we take min 1.5% and max. 2% steel.
It will be 1.5 cum to 2.0 cum steel.
1.5x7850= 11775kg/cm3 (min.)
2.0x7850= 15700kg/cm3 (max.)
(7850 is density of steel per cum)

Answer / shaik muneer

calculate the volume of slab ie L*B*H(H=depth of slab
convert this in meters to get whole answer in cum)than
multiply this with density of steel ie(7850kg/m3)this will
give u the steel in kgs to get it in tons divide result by
1000 hence done this is a rough estimate....
