1. What is Aggregate Density?

Definition: Density of aggregate is the mass per unit volume of materials like gravel, crushed stone, or sand, typically measured in kg/m³.

Purpose: Knowing aggregate density is crucial for material estimation, structural calculations, and quality control in construction projects.

2. How Does the Calculator Work?

The calculator uses the density formula:

Where:

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

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

3. Importance of Aggregate Density

Details: Density affects material strength, compaction characteristics, and volume calculations for construction projects.

4. Using the Calculator

Tips: Enter the mass of aggregate in kilograms and its volume in cubic meters. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical density range for aggregates?
A: Most aggregates have densities between 1500–1800 kg/m³, depending on material type and compaction.

Q2: How does moisture affect density measurements?
A: Wet aggregates will have higher apparent density due to water filling voids between particles.

Q3: 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.

Q4: How do I measure aggregate volume accurately?
A: Use a calibrated container or water displacement method for irregular shapes.

Q5: Why is density important in concrete mix design?
A: Density affects the weight and volume relationships in concrete mixtures, impacting strength and workability.
