also called "lightweight or buoyant concrete, is made by reducing its density using lightweight aggregates or air-entraining techniques. Here’s a short guide:
Key Steps to Make Floating Concrete: 1. Lightweight Aggregates – Use porous materials like: - Expanded clay/shale - Perlite - Pumice - Polystyrene beads
2. High Air Content – Introduce air bubbles using: - Foaming agents - Aerated concrete techniques
3. Low Density Mix– Keep density below 1000 kg/m³ (water’s density is ~1000 kg/m³).
4. Waterproofing – Coat with waterproof materials (epoxy, acrylic) to prevent water absorption.

4. Waterproofing – Coat with waterproof materials (epoxy, acrylic) to prevent water absorption.
Applications:
- Floating platforms
- Marine structures
- Decorative ponds
Note:
Regular concrete (2400 kg/m³) sinks, but lightweight mixes with enough air/voids float.
