From measurements to materials
The member dimensions give concrete volume and form-contact area. The chosen mix gives the concrete constituents; the supplied bars or bar-bending schedule give the steel weight.
Put the numbers in context
A column uses height × width × depth for concrete and its four side faces for shuttering; supplied bar lengths determine steel weight.
This illustrates the method; your inputs determine your result.Assumptions to check
- Member dimensions, concrete mix and reinforcement details come from approved project information.
- Column shuttering includes four sides, beam shuttering two sides and Beam Bottom (Tali), and slab shuttering the Slab Bottom (Tali).
Limits of this calculation
- This workflow calculates quantities only. It does not size members, design concrete, select reinforcement, or verify structural safety.
Common questions
Does the calculator decide how much rebar is safe?
No. Enter bars or a bar-bending schedule supplied for the project; the calculator only converts that information into weight and purchase quantity.
What will the result include?
Concrete volume and shuttering sheets are calculated from dimensions. Cement, sand, aggregate and steel require your supplied mix and bar details.
