Steel fiber reinforced polymer concretes were developed for utilization in large precast vaults. The data obtained indicate that polyester resin concrete reinforced with steel fibers will provide a ductile composite allowing structural engineers to design vaults capable of withstanding HS-20 loadings. Epoxy resin concretes exhibit higher flexural strengths; however, they do not carry loads beyond the yield point of the composite and are considered too brittle for this application. Several vaults were cast and have been placed in service.
