Concrete Aggregate Calculator
When a contractor decides to batch their own concrete from scratch, ordering the right amount of Portland cement is only half the battle. You also have to call the local quarry and order delivery for massive piles of sand and stone.
By using our concrete aggregate calculator, you can quickly estimate how many tons or cubic yards of aggregate you need to order to satisfy a 1:2:3 or 1:2:4 concrete mix ratio.
How Much Sand and Stone for Concrete?
Aggregates make up a massive 70% to 80% of the total volume of concrete. The Portland cement only acts as the glue to hold those rocks together.
If you are using a standard 1:2:3 mix ratio, finding out how much sand and stone for concrete you need is a matter of volume. To produce one cubic yard of concrete (which weighs about 3,900 lbs), you will need approximately:
- Fine Aggregate (Sand): ~1,400 lbs (0.7 Tons)
- Coarse Aggregate (Gravel): ~1,800 lbs (0.9 Tons)
- Portland Cement: ~470 lbs
- Water: ~250 lbs
Because quarries sell materials by the ton, our sand and gravel calculator for concrete automatically converts cubic yards into tonnage, taking the guesswork out of placing your order.
Aggregate Volume Calculator for Sub-Bases
Aggregates are not only used inside the concrete mixture itself. You also need hundreds of pounds of compacted gravel to create a solid foundation underneath the concrete slab.
Our tool works perfectly as a general aggregate volume calculator for estimating sub-bases. Most residential driveways and patios require a 4-inch compacted layer of Crushed Concrete, Class 5 gravel, or #57 stone. Simply use the tool to calculate the volume of your driveway area at a 4-inch depth to find out exactly how many tons of gravel you need to order for your base.
