Concrete Columns
Estimate concrete volume required for concrete columns.
Concrete is in general calculated in cubic yards (cy).
The concrete required for 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
