Abstract:
Concrete-polymer materials that include polymer-impregnated concrete (PIC), polymer concrete (PC) and polymer-modified concrete (PMC), have been developed within the past 50 years. PIC, which started out with great promise, has essentially disappeared from the scene. PC has been widely used for repairs, floor and bridge overlays, and precast components, but has not achieved the volume of use that had been projected. PMC has been widely used for overlays and repairs, including spray-on applications. There are many potential applications for the future related to materials processing and applications, which will ensure these materials will continue to be important in the construction field.

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.

Acrylic polymers are widely recognized for their excellent UV durability and water resistance properties. When acrylic polymers are used as modifiers in Portland cement formulations, those polymer properties translate into excellent long-term outdoor durability and wet adhesion durability in the modified concrete. A number of lab prepared series of acrylic polymer modified portland cement formulations have been placed in outdoor exposure and tested periodically for the durability of various properties. Some of these experimental series have been on exposure for as long as 30 years. The results of these studies indicate that acrylic polymers are the ideal cement modifiers with respect to outdoor durability and wet adhesion durability.

The construction, performance and use of polymer concrete bridge overlays over the past 25 years is summarized. Polymer concrete overlays that have an established history of use and acceptance include multiple-layer epoxy, multiple-layer epoxy urethane, methacrylate slurry and premixed polyester styrene. Evaluations indicate that polymer concrete overlays can provide skid resistance and protection against intrusion by chloride ions for 25 years and are an economical technique for extending the life of concrete decks, particularly when overlays must be constructed during off-peak traffic penods to minimize inconvenience to motorists.

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.
