Construction

Air content can either strengthen or weaken concrete, depending on how well it is controlled. Evonik’s SITREN AirVoid®  solutions enable precise management of air void size, distribution, and stability.

Customer Benefits

• Improved freeze-thaw durability and resistance to de-icing salts
• Higher mechanical strength through reduction of unwanted air
• Better workability and surface quality
• Consistent performance across varying process conditions

Value: Maintain the optimal balance between durability and strength across production, transport, and application.

Water ingress is a major cause of concrete deterioration. TEGOSIVIN® water repellents protect structures by reducing water absorption while preserving breathability. In addition, SITREN® self-healing technology actively contributes to durability by sealing microcracks when in contact with moisture, helping to prevent further damage and extend service life.
