3.3—Antifreeze for Cement

Water-soluble additive for cement that inhibits ice recrystallization and shapes ice dynamically at freezing temperatures, reducing freeze-thaw damage without compromising strength. Inspired by antifreeze proteins, it offers a durable alternative to air-entraining agents. While targeted at building materials, the technology has broad potential in markets like organ preservation, aerospace, energy and food—anywhere frost damage is a concern.
