1. What is Density of Coarse Aggregate?

Definition: Density is the mass per unit volume of coarse aggregate (typically 10-40mm size stones used in construction).

Typical Range: The density of coarse aggregate generally ranges between 1450-1600 kg/m³ depending on material type and compaction.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \rho = \frac{m}{V} \]

Where:

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

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

3. Importance of Density Calculation

Details: Knowing aggregate density is crucial for concrete mix design, structural calculations, and material quantity estimations.

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 affects coarse aggregate density?
A: Particle size distribution, shape, mineral composition, moisture content, and compaction level.

Q2: How does density affect concrete properties?
A: Higher density aggregates typically produce stronger, more durable concrete.

Q3: What's the difference between bulk density and particle density?
A: Bulk density includes voids between particles, while particle density is the solid material only.

Q4: How should I measure volume for this calculation?
A: Use a calibrated container and measure the volume occupied by loosely packed aggregate.

Q5: Why does density vary between aggregate types?
A: Different rock types (granite, limestone, etc.) have different mineral compositions and porosities.
