What is Defoamers for Cementitious Compositions about?

The invention presents a novel additive composition for controlling air in hydratable cementitious compositions, specifically utilizing a polyalkoxylated polyalkylene polyamine defoamer in conjunction with air-entraining agents. This approach aims to manage air void content effectively, enhancing the freeze-thaw durability and compressive strength of concrete. The composition includes various agents and maintains a specific ratio to optimize performance while preventing phase separation.
