1. What is Hardcore Density?

Definition: Density of hardcore (e.g., crushed stone) is typically 1500–1800 kg/m³.

Purpose: Calculating density helps determine material quantity needed for construction projects and ensures proper structural support.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density (kg/m³)
• \( m \) — Mass (kg)
• \( V \) — Volume (m³)

Explanation: The mass of the material is divided by its volume to determine its density.

3. Importance of Density Calculation

Details: Knowing the density of hardcore materials helps in:

• Estimating material requirements
• Calculating structural loads
• Ensuring proper compaction
• Budgeting for material costs

4. Using the Calculator

Tips:

• Enter the mass in kilograms (kg)
• Enter the volume in cubic meters (m³)
• Both values must be greater than 0
• Typical hardcore density ranges between 1500–1800 kg/m³

5. Frequently Asked Questions (FAQ)

Q1: What is considered hardcore material?
A: Hardcore typically includes crushed stone, gravel, broken bricks, concrete rubble, and other compactable materials.

Q2: Why does density vary?
A: Density varies based on material type, particle size, moisture content, and compaction level.

Q3: How do I measure volume for irregular shapes?
A: For irregular shapes, use water displacement method or calculate based on the space being filled.

Q4: What's the difference between bulk density and particle density?
A: Bulk density includes voids between particles, while particle density is the material's intrinsic density excluding voids.

Q5: How does moisture affect density?
A: Moisture increases mass (and thus density) but can also affect compaction characteristics.
