Evaluation of Epoxy Resin Systems as Backing Materials for Miter Gates.
Abstract
This study was conducted because of problems encountered with epoxy resin backing material when used as a filler for setting quoin and miter blocks of lock miter gates. The problems were failure of the epoxy system to set and softening after being submerged in water over a period of time. Laboratory tests were developed to evaluate different epoxy resins when used as a filler for setting quoin and miter blocks of lock miter gates. The epoxy resins were tested for effect of curing temperature and thickness on compressibility; effect of curing time on strength; water absorption; effect of moisture on surface hardness; effect of temperature on strength; effect of freezing and thawing on shelf life; flowability in narrow spaces; and compression under water. Five epoxy resins were tested for the parameters originally requested by the Mobile District. Five more systems were tested for compressive strength, water absorption, and the resistance to softening under water as later requested by the Mobile District. Based on the test results, two systems were found to be the most promising.
