1. What is Density of Ground Granulated Blast-furnace Slag (GGBS)?

Definition: GGBS density is the mass per unit volume of this cementitious material, typically ranging between 2800-3000 kg/m³.

Purpose: Understanding GGBS density is crucial for concrete mix design, material handling, and structural calculations.

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 GGBS is divided by its volume to determine its density.

3. Importance of GGBS Density

Details: Accurate density values are essential for:

• Proper concrete mix proportioning
• Structural load calculations
• Material storage and transportation planning
• Quality control in construction

4. Using the Calculator

Tips:

• Measure the mass of GGBS in kilograms (kg)
• Measure the volume in cubic meters (m³)
• Typical GGBS density ranges from 2800 to 3000 kg/m³

5. Frequently Asked Questions (FAQ)

Q1: What is the typical density range for GGBS?
A: Ground Granulated Blast-furnace Slag typically has a density between 2800-3000 kg/m³.

Q2: How does GGBS density compare to Portland cement?
A: GGBS is slightly less dense than Portland cement (which is about 3150 kg/m³).

Q3: Why does density matter in concrete mix design?
A: Density affects the weight of concrete, which impacts structural design and material quantities.

Q4: Can GGBS density vary?
A: Yes, density can vary slightly based on particle size distribution and moisture content.

Q5: How do I measure volume accurately?
A: Use precise volumetric containers or calculate from dimensions for large quantities.
