Abstract:
Polymer concrete (PC) overlays are often an effective way to repair or protect concrete surfaces exposed to hostile service conditions. The various applications of PC overlays include industrial floors exposed to abrasion and chemical spillage, concrete spillways and water conveyance structures exposed to abrasion erosion and freeze-thaw attack, and bridge decks exposed to severe weather conditions, deicing salts, and heavy traffic. Three general types of PC overlays are used premixed PC, multiple-layers PC, and slurry PC. Polymer binders include methacrylate monomer systems, and epoxy, polyester, and vinyl ester resins systems. Applications of PC overlays and progress in the development of standards are discussed.
