Product Description

CSA-Based Shrinkage-Compensating Construction Additive, High-Performance Concrete Expansion Additive

Product Description:

A high-performance calcium sulfoaluminate (CSA)-based expansive agent designed to compensate for drying shrinkage and thermal contraction in cementitious materials. It generates controlled expansion during hydration, enhancing concrete durability by preventing cracks in critical structures. Ideal for projects requiring dimensional stability and watertightness.

 
Specifications
Purity 95-99%
Decomposition Temperature 160-220°C (varies by type)
Particle Size 5-50 μm (powder), 1-3 mm (granules)
Color White/Yellow/Off-white
 
Application

 

  1. 1. Construction:

    • Compensate shrinkage in concrete (e.g., bridges, tunnels).

    • Produce lightweight prefabricated panels.
       

  2. 2. Polymers:

    • Create foamed PVC (flooring, cables), EVA (shoe soles).
       

  3. 3. Ceramics:

    • Reduce kiln firing defects via controlled expansion.
       

  4. 4. Rubber:

    • Vulcanization aids for spongy rubber products.
       

  5. 5. Packaging:

    • Expandable polystyrene (EPS) for insulation.

 
Package and storage

 

Packaging:

  • 25 kg woven bags with moisture-proof lining.

  • 1-ton bulk bags (FIBCs) for industrial buyers.
     

Storage:

  • Keep in dry, cool conditions (<30°C, humidity <50%).

  • Avoid direct sunlight and contact with acids/bases.
