Query Fan-Out Deep-Dives: Formulas & Bag Math

1. How to calculate cubic yards of concrete for a slab?

BLUF Answer: Concrete volume is calculated by multiplying length by width by depth in feet, then dividing by 27 (since $1 \text{ yd}^3 = 27 \text{ ft}^3$).

Cubic Yards = (Length_ft ร— Width_ft ร— Depth_inches / 12) รท 27

2. How many premix bags are in 1 cubic yard of concrete?

BLUF Answer: One cubic yard ($27 \text{ ft}^3$) yields:

  • 80lb Bags: 45 bags (yields $0.60 \text{ ft}^3$ per bag).
  • 60lb Bags: 60 bags (yields $0.45 \text{ ft}^3$ per bag).
  • 40lb Bags: 90 bags (yields $0.30 \text{ ft}^3$ per bag).

3. What is the 1.54 dry volume compaction factor?

BLUF Answer: Dry cement, sand, and gravel compact by 54% when mixed with water. To obtain $1 \text{ m}^3$ of wet poured concrete, you need $1.54 \text{ m}^3$ of raw dry ingredients.
