Crushed Concrete Calculator

The Crushed Concrete Calculator is designed to help you estimate the volume and weight of crushed concrete required for your project based on length, width, and depth. By converting depth from inches to feet and calculating volume in cubic yards, it provides a practical estimation for material requirements.

Calculation Formula

1. Convert Depth to Feet:
   \[ \text{Depth (in feet)} = \frac{\text{Depth (in inches)}}{12} \]

2. Volume in Cubic Yards:
   \[ \text{Volume (cubic yards)} = \frac{\text{Length (ft)} \times \text{Width (ft)} \times \text{Depth (ft)}}{27} \]

3. Estimated Weight (tons):
   \[ \text{Weight (tons)} = \text{Volume (cubic yards)} \times 1.4 \]

Example Calculation

If your project area is 20 feet long, 10 feet wide, and requires a depth of 6 inches, the calculations would be:

\[ \text{Depth (ft)} = \frac{6}{12} = 0.5 \text{ feet} \]

\[ \text{Volume (cubic yards)} = \frac{20 \times 10 \times 0.5}{27} \approx 3.70 \text{ cubic yards} \]

\[ \text{Weight (tons)} = 3.70 \times 1.4 \approx 5.18 \text{ tons} \]

Common FAQs

1. What is crushed concrete used for?

   • Crushed concrete is commonly used for driveways, pathways, and as a base material for various construction projects.

2. How accurate is the weight estimate?

   • The weight is based on an average value of 1.4 tons per cubic yard, which is a common estimate. Actual weight can vary slightly based on material density.

3. How deep should crushed concrete be for a driveway?

   • Typically, a depth of 4-6 inches is recommended for driveways depending on the load and intended use.
