Every beam shape uses a different cross-sectional area formula. The volume is always: cross-sectional area × length. Below are the standard formulas for all five beam types in this guide.

Instantly estimate volume (m³) and weight (kg / tonnes) of aggregate for driveways, sub-bases, concrete, drainage & landscaping projects.

Instantly estimate the exact quantities of cement bags, fine aggregate (sand), coarse aggregate, and water needed for slabs, beams, columns, footings, walls, and staircases.

Estimate the exact admixture dosage by weight of cement — instantly. Plasticizers, superplasticizers, retarders, accelerators & more.

Estimate the ideal w/c ratio, water quantity & concrete strength rating for any mix grade.

Get precise material quantities for every concrete grade — from lean M10 blinding to ultra-high-strength M60. Covers nominal mix (M10–M25) and designed mix (M30–M60) using IS 10262, ACI 211.1 and BS EN 206 methods.

Estimate concrete volume for flat roofs, ground-floor slabs, suspended slabs, and any rectangular or square concrete slab.

Instantly estimate mix proportions for M15 to M50 concrete using IS 10262:2019 or ACI 211.1 methods. Get quantities per m³ and for your total project volume.

Estimate concrete volume for rectangular, square, and circular columns — instantly. Results in m³, ft³, litres, and cement bags with a complete materials list.

Estimate concrete volume, weight, and quantities for pad footings, strip footings, and combined footings — instantly, for any project.
