Epoxy Resins for Jointing Segmentally Constructed Prestressed Concrete Bridges.

摘要

This report presents the general requirements for epoxy resins for jointing segmentally constructed prestressed concrete bridges using the cantilever erection method. The report outlines the main function of the epoxy resin material in this type structure,and discusses the development of specific performance requirements for the epoxy resins. Simple test methods and jointing conditions for evaluation of the suitability of epoxy resins for this specific application are suggested. Test results indicated the importance of proper surface preparation and particularly a removal of all traces of oil from the surface of the specimens to be jointed. The report includes a recommendation in detailed specification form for epoxy resin material and jointing procedures for this construction application.
