Calculation Formula

Common Mix Ratios

• 1:2:4 (Standard Concrete): General construction, slabs, beams
• 1:1.5:3 (High Strength): Structural elements, columns
• 1:3:6 (Lean Mix): Foundations, mass concrete
• 1:3 (Plaster): Standard cement-sand mortar
• 1:4 (Plaster): Internal walls, lean plaster
• 1:6 (Brick Mortar): Brick masonry work

Why Use This Calculator?

Manual cement calculations are complex and error-prone. This calculator uses industry-standard formulas including dry volume factor (1.54) and standard cement bag volume (0.035 m³) to provide accurate estimates. Save time, reduce waste, and ensure you order the right amount of materials for your construction project.
