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

Concrete required per 1 ft Column Height

• 1 cu yd per linear foot (y³/ft) = 2.5 m³/m
