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.

A novel and innovative use of polymer concrete to precast a dome is described. The finished dome meets architectural criteria for the project and is lightweight and durable, making field installation easier and faster. The project demonstrates the versatility of architectural precast polymer concrete.

This paper reviews the history of polyester polymer concrete highway and bridge deck overlay with a focus on the work done in California and adjacent states. The paper discusses the early work done at Brookhaven Labs, the watershed I-80 job done at Donner Pass (including updates relating to the job), and then reviews the large number of successes over the last thirty years.

This paper discusses polymer impregnation in the repairs of concrete damaged by cavitation/erosion at Dworshak dam. Impregnation was performed on conventional concrete, fibrous concrete, and dry-pack patches. The repairs included vertical and horizontal surfaces. Testing which demonstrated the improved resistance of polymer impregnated concrete to cavitation and erosion damage are summarized. With approximately 25 years of experience, the repairs have performed extremely well, although it should be noted that modifications were made about 8 years after the polymer repairs to minimize cavitation in the outlets by aeration. To date, this is the most complex known polymer impregnation project performed under a construction contract.

The historical development of polymer-impregnated concrete (PIC) is reviewed. Starting in 1965, PIC was developed over a period o f several years as part of a joint research program conducted by the Bureau of Reclamation (USBR) and Brookhaven National Laboratory (BNL) under sponsorship of the USBR, Atomic Energy Commission (ARC), and the Office o f Saline Water (OSW). At various times other organizations funded portions of the program aimed at developing applications directed at their particular interests. Following reports of the research results, research was also conducted by many other organizations in the US and worldwide. The paper reviews the various processes and equipment used to produce both partial and fully impregnated concrete. Included are discussions on drying the concrete, placing it under vacuum, pressure soaking, encapsulation, and polymerization techniques. Monomer and catalyst systems arc also discussed. Costs and safety procedures are also mentioned. Comparisons of improvements in properties of PIC over conventional concrete are given.
