How is sand quantity calculated for concrete?
Sand volume is derived from the total concrete volume multiplied by the grade-specific sand ratio per cubic metre.
Sand Quantity Calculator
Calculate sand volume and weight required for a concrete pour by dimensions, grade, and wastage.
Sand Quantity Calculator Formula
- Concrete Volume
Length × Width × Thickness (converted to m³) - Wastage Allowance
Volume × (1 + Wastage ÷ 100) - Sand Volume
Adjusted volume × sand ratio per m³ for grade - Sand Weight
Sand volume × 1600 kg/m³
Assumptions
- Sand ratios follow standard nominal mix proportions for each concrete grade.
- Loose sand density is approximated at 1600 kg/m³.
- Moisture content and compaction are not included in weight estimates.
Frequently Asked Questions
Can I use this for mortar sand?
This tool is for concrete mix sand. For plaster mortar, use the Plaster Material Calculator.
Why is weight shown as well as volume?
Many suppliers sell sand by weight (tons) while mix designs reference volume.
