Concrete structures in cold climates face significant challenges due to freeze-thaw cycles, which can lead to expansion, cracking, and spalling, compromising their integrity and longevity. Traditional methods to mitigate freeze-thaw damage, such as air-entraining agents and sealers, have limitations in providing long-term protection and durability. This article explores the use of biomimetic antifreeze polymers as a novel solution to enhance concrete strength and resilience in cold weather. Inspired by natural antifreeze proteins found in organisms like Arctic fish and insects, these polymers are engineered to inhibit ice formation and growth within the concrete matrix. We discuss the process of integrating these bio-inspired polymers into concrete mixes, including optimal incorporation techniques and concentrations. Laboratory testing and field trials demonstrate that concrete enhanced with biomimetic antifreeze polymers exhibits significantly improved freeze-thaw resistance, reduced cracking, and extended ...
