INITIAL STUDY OF VINYL ESTER POLYMER SHOTCRETE

A limited study of vinyl ester polymer concrete was conducted to investigate its potential for shotcrete application. Polymer shotcrete is applied using modified conventional shotcrete equipment, but differs from conventional shotcrete in that a polymeric binder is used in lieu of portland cement and water. The polymer-shotcrete application was partly successful, but further work is needed to improve mixing of materials at the nozzle of the gun. Vinyl ester shotcrete cures in 5 to 10 minutes for a rapid cure system after application, develops full compressive strength ranging upwards to 92 MPa (13,400 lb/sq in.) upon curing, and could have potential applications in areas in which these properties would offer definite benefits over conventional shotcrete. Polymer shotcrete requires that certain safety precautions be taken to assure safe use. /Author/
