Aggregate Quantity Calculator

Estimate coarse aggregate from a wet concrete volume and a mix ratio, using a dry volume factor of 1.54.

Wet concrete volume (m³)Mix

How this number is worked out

Aggregate is the coarse-aggregate share of the dry volume. Dry volume is 1.54 × wet volume. This is a planning estimate. Confirm quantities against the structural drawings before ordering or cutting material.
