Abstract:

The U. S. Electric Power companies purchase over $500 million insulators per year for outdoor and indoor use. A variation of polymer concrete appears to have the necessary characteristics to replace a large proportion of the insulation presently in use. Over four years of development and testing by the Electric Power Research Institute (EPRI) and its counterpart in Mexico indicate the material is now suitable for commerciali-zation. A wide range and variety of applications are expected.

Abstract:

Every segment of the transportation industry is experiencing maintenance problems with rapidly deteriorating portland cement concrete structures. The Federal Highway Administration, aware of such problems, has sponsored research and development work to find a rapid-setting durable composite that can be used to repair deteriorated concrete and/or to effectively reduce chloride and moisture penetration into concrete.

Abstract:

The Air Force Engineering and Services Center (AFESC) at Tyndall AFB, Florida is currently engaged in a seven-year research and development effort to rapidly repair bomb damaged concrete runways. Polymer concrete because of rapid cure and high strength is one of the most promising methods of repair. The problems of moisture, temperature extremes and mechanization are all being studied for development of a rapid all-weather polymer concrete repair system. Research includes work at the University of Texas at Austin, AFESC, Battelle Columbus Labora-tories, Brookhaven National Laboratory, and the BDM Corporation. Polymers being considered include acrylics, epoxies, polyesters and furans.

Abstract:

Epoxide resin concrete produced by vacuum impregnation of a prepacked aggregate has handling properties and stiffness (40 GN/m 5 reatly improved at 70 C) when compared with conventionally mixed and placed epoxide resin concrete. This material has been developed for superconducting turbogenerators, but with its improved qualities coupled with high strength (150 MN/m ), resistance to aggressive environments, impervious nature, low shrinkage and electrical resistance a wide range of applications is forecast.
