Sand Quantity Calculator – Estimate Fine Aggregate
Quality Inspector
Estimate the quantity of sand (fine aggregate) needed for a given volume of concrete and mix ratio.
📐 Formula & Method
Sand volume = (Sand Part / Sum of Parts) × Dry Volume. Weight is estimated using an average density of 1600 kg/m³.
Sand (m³) = (Sand Ratio / Total Ratio) × Volume × 1.54
📋 Worked Example
For 2m³ of M20 (Sum=5.5, Sand=1.5): • Sand = (1.5/5.5) × 2 × 1.54 = 0.84 m³
❓ Frequently Asked Questions
This calculator uses 1600 kg/m³ as the average density for dry sand.
