1. What is Density of Fine Aggregate?

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

Purpose: Understanding density helps in material selection, quantity calculations, and structural design in construction projects.

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 fine aggregate is divided by its volume to determine its density.

3. Importance of Density Calculation

Details: Density affects concrete mix design, structural calculations, and material transportation. Typical fine aggregate density ranges between 1600-1750 kg/m³.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is considered fine aggregate?
A: Materials passing through a 4.75mm sieve, primarily natural sand or crushed stone dust.

Q2: Why does density vary?
A: Density varies based on particle size, shape, moisture content, and mineral composition.

Q3: How does moisture affect density?
A: Wet sand can be 20-30% heavier than dry sand due to water filling voids between particles.

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

Q5: How is this used in concrete mix design?
A: Density helps determine the weight of sand needed for a specific volume in concrete mixtures.
