1. What is Density of 20mm Aggregate?

Definition: This calculator determines the density of 20mm aggregate based on mass and volume measurements.

Purpose: It helps construction professionals and material suppliers verify the density of coarse aggregates used in concrete and other applications.

2. How Does the Calculator Work?

The calculator uses the density formula:

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 Aggregate Density

Details: Knowing the density of 20mm aggregate is crucial for:

• Concrete mix design
• Material quantity calculations
• Quality control of aggregates
• Structural calculations

4. Using the Calculator

Tips:

• Measure the mass of aggregate in kilograms
• Measure the volume it occupies in cubic meters
• Typical density range for 20mm aggregate: 1450-1550 kg/m³

5. Frequently Asked Questions (FAQ)

Q1: What is 20mm aggregate?
A: It's coarse aggregate material where most particles pass through a 20mm sieve, commonly used in concrete.

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

Q3: How to measure volume accurately?
A: Use a calibrated container and measure the displaced water volume or calculate from container dimensions.

Q4: 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.

Q5: How does moisture affect density?
A: Wet aggregate has higher mass due to water in pores, increasing apparent density.
