Following various hydration times (l to Z8 days) concrete was impregnated with an epoxy resin system. For a given impregnation condition (vacuum, pressure and time), it was found that higher polymer Ioadings were achieved in specimens having shorter hydration times. Compressive modulus and compressi

โฆ Synopsis
Impregnation of concrete with two types of hot epoxy resins was investigated. Compared with the more commonly used acryIics, epoxies offer reduced danger from fumes, fire and explosion.
Economic advantages due to the reduction or elimination of the post-drying cool-downperiod are also afforded by the epoxy. This study revealed that an aliphaticbased epoxy impregnant at I05 ยฐC displays an uptake rate approaching that of acrylic monomers.
However, the narrow span between the polymerization and degradation temperatures could limit applicability.

## Abstract A multifunctional epoxy tetraglycidyl dibenzmethyldiamine and triglycidyl benzylamine were blended, respectively, into impregnation resin, which mainly consists of diglycidyl ether of bisphenol A (DGEBA) and acid anhydride hardener. This resin is expected to impregnate HTโ7U superconduc
