To Calculate quantity of Steel in Slab , Beam, Column & Footing
Slab area is 400 square meter, thickness of the slab is 150 mm. Concrete quantity required to cast this slab is 400*0.15 = 60 Cubic meter. fter calculatin! concrete quantity, you can remember these thumb rules "ust for !ettin! a basic idea of ho# much quantity of steel is required in those structural members. Steel quantity in a con$entional slab %e&cludin! its beams' #ill be around 60 to 65 (! )er Cubic meter. n beams it #ill be around +00 to ++0 k! )er cubic meter. n columns itll be around +00 to +50 k! )er cubic meter. -or raft footin!s itll be around 100 to 1+0 k! )er cubic meter.
