Correct answer: C. Pans
Detailed Explanation: Concrete Transport by Pans in Small Works
Why C (Pans) is correct: In small construction projects where the volume of concrete is low and distances are very short, the simplest and most economical method is manual transport using pans (shallow metal or bamboo/cane baskets). Workers carry these on their heads from the mixer to the placement point. While labour-intensive, no specialised equipment is needed.Concrete Transportation Methods by Scale
| Method | Scale | Distance | Volume |
|---|---|---|---|
| Pans (head loads) | Very small | <30–50 m | Small batches |
| Wheel barrow / hand cart | Small | <100 m | 0.1–0.3 m³ per load |
| Dumper / tipper truck | Medium–large | 100–1000 m on site | 2–6 m³ per load |
| Conveyer belt | Large continuous works | Up to 300 m at ~1.5 m/s | High throughput |
| Pump & pipeline | Large / high-rise | 400 m horizontal, 80 m vertical | Very high throughput |
| Transit mixer | RMC; large projects | 5–20 km road | 4–7 m³ per trip |
- Pans = manual transport method for small works over very short distances.
- Disadvantage: high labour cost; risk of segregation if pans are tilted; slow.
- For larger volumes or distances, mechanised methods (wheel barrow, dumper, pump) are preferred.
