Understanding Your Crushed Concrete Needs
Crushed concrete is a versatile recycled aggregate material commonly used in construction and landscaping projects. It's produced by crushing old concrete from demolition sites, then screening it to a specific size. Its uses include base material for driveways and pathways, sub-base for roads, drainage layers, and even as a component in new concrete mixes.
To accurately calculate the amount of crushed concrete you need, you'll typically be working with measurements of length, width, and depth. The depth is often given in inches, while the length and width are usually in feet. It's crucial to convert all measurements to a consistent unit before calculating volume.
Key Metrics:
- Volume: The total space your crushed concrete will occupy. We usually calculate this in cubic feet and then convert to cubic yards, as aggregates are often sold by the cubic yard.
- Weight: The density of crushed concrete varies, but a common figure is around 2,500 lbs per cubic yard. Knowing the weight helps in estimating costs if the material is priced by the ton.
- Cost: The total expenditure for the crushed concrete, often based on its weight (per ton).
This calculator simplifies the process by taking your project dimensions and material cost information to provide an estimate of the total volume, weight, and cost of crushed concrete required. Ensure your measurements are accurate for the best results.

return;
}
// Convert depth from inches to feet
var depthFeet = depthInches / 12;
// Calculate volume in cubic feet
var volumeCubicFeet = length * width * depthFeet;
// Convert volume to cubic yards (1 cubic yard = 27 cubic feet)
var volumeCubicYards = volumeCubicFeet / 27;
// Calculate weight in tons (1 ton = 2000 lbs)
var weightLbs = volumeCubicYards * density;
var weightTons = weightLbs / 2000;
// Calculate total cost
var totalCost = weightTons * costPerTon;
