Understanding Concrete Calculations
Key factors in concrete calculations:
- Volume: Length × Width × Depth (or πr²h for circular)
- Area: Length × Width (or πr² for circular)
- Thickness: Typically 4-6 inches for most applications
Common Applications
- 4 inches: Walkways, patios, sidewalks
- 5 inches: Residential driveways
- 6 inches: Heavy traffic areas, parking
- 8+ inches: Industrial applications
Material Ratios
- 1 cubic yard = 27 cubic feet
- 6 bags of cement per cubic yard
- 1 ton of sand per cubic yard
- 1.5 tons of gravel per cubic yard
