HOW TO ESTIMATE GRANITE CHIPPINGS FOR CONCRETE
A quick reference guide for site supervisors, engineers, and private home builders across South East Nigeria.
1. Formula for Volume
Volume = Length (m) × Width (m) × Thickness (m).
Example: A 150m² floor slab with 150mm (0.15m) thickness requires: 150 × 0.15 = 22.5 m³ of concrete.
2. Concrete Mix Ratio
In standard 1:2:4 structural concrete (1 cement, 2 sand, 4 granite), approximately 0.8 m³ to 0.9 m³ of granite is needed per cubic meter of finished concrete.
Density: 1 cubic meter of compacted 3/4" granite weighs approximately 1.60 metric tons.
3. Compaction Allowance
Always account for 5% to 10% site wastage, uneven ground sub-base variations, and mechanical vibrator compaction loss.
Rule of Thumb: Round up to the nearest full tipper load to prevent mid-pour concrete shortages.
