Abstract:Polymer concrete (PC) has been widely used for repairing concrete bridges and pavements. The primary advantages are its rapid curing and high strength. The materials include a monomer, a cross-linking agent, a promoter, an initiator, and an aggregate. Other materials can be added to improve the workability and to improve the ductility and toughness. PC can be made by one of several methods: (1) prep laced aggregate saturated with monomer which is poured or sprinkled; (2) prep laced aggregate with monomer injected using in-line mixing systems; (3) conventional concrete mixers; (4) mobile concrete batching units. Finishing is accomplished by screeding or troweling. Safety procedures must be maintained in mixing, handling, storing, and in construction. Safety requirements are outlined.
