Current QUIKRETE No. 1101 documentation lists about 0.30 ft³ for 40 lb, 0.45 ft³ for 60 lb, and 0.60 ft³ for 80 lb. The product is for placements at least 2 inches (50 mm) thick.
- Do not mix yields from different bag sizes or products.
- Use finished concrete dimensions.
- Design, reinforcement, base, joints, and curing remain separate decisions.
Formula or decision boundary
adjusted cubic feet ÷ selected bag cubic-foot yield; round upCurrent No. 1101 yield rows
| Bag | Stated approximate yield | Purchase rule |
|---|---|---|
| 40 lb | 0.30 ft³ / 8.5 L | round up |
| 60 lb | 0.45 ft³ / 12.7 L | round up |
| 80 lb | 0.60 ft³ / 17 L | round up |
Use the answer
Calculate geometry
Use a rectangular or cylindrical formula that matches the actual placement.
Select the bag
Match the exact No. 1101 size stocked for the project.
Round the quotient
Keep full precision until after dividing adjusted volume by yield.
Safety and scope
- Wet cement can cause serious burns; follow product safety instructions.
- Verify excavation, structural, frost, utility, and code requirements locally.
