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.
