Zero Aggregate (Bahs Zero)
Overview
Zero aggregate, commonly referred to as “Bahs Zero,” is a fine crushed stone material widely used in construction. It is produced by crushing larger stones into small, uniform particles, making it suitable for various applications, including concrete mixes, paving, and road foundations. Its compact nature and high durability make it an essential component in many structural and decorative uses.
Why You Should Use It?
- High Compactness: Provides a solid base for roads and pavements.
- Improves Concrete Strength: Enhances the structural integrity of concrete mixtures.
- Versatile Usage: Suitable for construction, landscaping, and drainage solutions.
- Excellent Binding Properties: Works well in binding cement and asphalt mixes.
- Eco-Friendly Material: Sourced from natural stone, making it sustainable.
