6.00 KG - Admixture Additive for Lightweight Concrete

Additive for Lightweight Concrete to Mix with Polystyrene Beads.

This additive is compatible with all types of lightweight aggregates: polystyrene beads, cork, expanded clay, pumice stone, etc. It optimizes the strength and density of light or reduced-weight concretes and mortars, offering an ideal solution for work requiring a more manageable and insulating material.

Instructions:

1. Adding in concrete mixer or blender:

   • Pour the additive after the cement (and possibly the sand) and water.
   • Mix for 2 to 3 minutes.
   • Incorporate the polystyrene beads or other lightweight aggregates.
   • Continue mixing for 4 to 5 minutes.
     
     

2. Use with truck mixer:

   • Add the additive and then the polystyrene beads directly on site.
     
     

3. Pumps or projection machines:

   • Introduce the additive after all the components.
   • Mix for about 5 minutes.

Recommended dosage:

• Light concretes and mortars: 1 to 2 kg/m³

Application temperature:

• Between 5°C and 35°C

Properties:

• Improved coating of polystyrene beads and other lightweight aggregates
• Uniform distribution of aggregates
• Excellent water retention
• Optimized manageability
• Strong adhesion for sprayed application
• Plasticizing effect

Applications of Lightweight Concrete:

• Production in BPE plant or on site
• Heavy and light precasting
• Coatings
• Traditional, insulating or soundproof screeds
• Renovation (filling, leveling without structural reinforcement)
• Thermal and sound insulation (slabs, walls, screeds)

Densities:

• Lightweight concrete: 300 to 1 800 kg/m³
• Traditional concrete: 1 900 to 2 400 kg/m³

Advantages:

• Simplified implementation
• Reduced weight compared to traditional concrete
• Improved thermal and acoustic performance
