Corrosion Protection Concrete for Marine Structures

Corrosion-resistant concrete additive that enhances concrete's natural durability through a novel polymer-based compound. The additive, comprising a silicone-based polymer, forms a hydrophobic surface layer that preferentially adheres to aggregate surfaces, while its polyether segments create hydrophilic modification sites for dispersion. This additive effectively disperses corrosion agents during mixing, forming a protective hydration gel network that shields aggregates from chloride penetration. The additive's directional enrichment on aggregate surfaces enables controlled formation of this protective hydration layer, reducing cracking and improving corrosion resistance compared to conventional hydration promoters.
