Preliminary RCC concrete volume for slabs, beams, columns and footings — optional mix materials and labelled steel thumb-rule ranges. Not a substitute for structural design.
Last updated: Aug 2026
V_wet = geometry × qty · V_order = V_wet × (1 + wastage%) · materials from dry × 1.54 × mix shares
Indicative steel (optional) = V_order × preliminary kg/m³ band for the element. Actual reinforcement must follow structural drawings by a qualified engineer.
Estimate RCC concrete volume for slabs, beams, columns and footings with optional mix materials. Indicative steel uses labelled preliminary ratios only — not a substitute for structural design. Indicative planning figures.
Example: 5 × 4 m slab, 150 mm thick, M20, 5% wastage. Wet = 3.0 m³; order ≈ 3.15 m³. Mix breakdown uses dry factor 1.54. If steel estimate is enabled, a preliminary kg/m³ range is shown with an engineer-drawing disclaimer.
Preliminary planning of concrete volume for slabs, beams, columns and footings, with optional cement/sand/aggregate from transparent mix assumptions. It is not a structural design tool.
No. When enabled, steel is only an indicative range from clearly labelled preliminary kg/m³ thumb rules. Actual reinforcement must follow structural drawings by a qualified engineer.
Order volume (after wastage) × dry factor 1.54, then split by the selected grade mix (e.g. M20 ≈ 1:1.5:3). Assumptions are listed on the result.
Yes. Use the linked slab, beam, column and footing calculators — each opens this RCC tool focused on that element. The general concrete calculator also covers geometric volumes.
