Concrete Columns

Estimating concrete required to concrete columns

concrete column

Concrete is in general calculated in cubic yards - cy

The concrete required in a column can be calculated as

v =  0.7854 a2 h / 27   (1)

where 

v = required concrete - cy (cu. yards)

a = column area (sq. ft.)

h = column height (ft)

 

  • 1 cubic yard = 27 cubic feet
  • 1 ft = 12 in
