Concrete Bag Yield and Dry-Mix Quantities
Understand litres per bag, density and why bag counts vary between products.

Concrete Bag Yield and Dry-Mix Quantities
Two bags with the same weight may not produce the same wet volume because aggregate grading and mix design differ. Use the declared yield in litres or cubic feet from the specific product. Convert that yield to cubic metres before dividing the order volume. Water is not added to finished volume as a separate quantity.
Worked example
2.52 m³ / 0.012 m³ = 210; 80 lb → 0.60 ft³
