Sand & Aggregate Calculator

Calculate sand and aggregate quantities for any custom concrete mix ratio.

Formula v1.0.0GlobalMethodologysand-aggregate-v1
How this is calculated
Dry volume = wet volume × 1.54; Sand/Aggregate = dry volume × (their ratio ÷ total ratio parts)

Assumptions used in this calculation

  • Dry volume factor: Uses the standard 1.54 multiplier to account for voids between aggregate particles.

About this calculator

The sand and aggregate calculator applies a custom cement:sand:aggregate mix ratio (by volume) to a wet concrete volume, using the standard 1.54 dry-volume factor, to estimate exactly how much sand and aggregate you need.

Worked example

100 cft wet volume, 1:1.5:3 mix

Result: Sand ≈ 46.2 cft, Aggregate ≈ 92.4 cft
