Maintenance and Repair of Concrete and Masonry Structures: Epoxy Pressure Grouting

摘要

Existing and revised methods used for pressure grouting cracked concrete and masonry were studied. Hand gun and pressure tank grout injecting equipment were studied as well as epoxy resin grouts. Job site visitations, laboratory, and controlled field tests were used as mechanisms to perform the evaluations. As a result of studying existing grouting techniques, materials and methods were selected for use in the laboratory and field. The best characteristics of several grouting methods were combined to develop a new technique. Grouting materials were selected on the basis of viscosity and bonding capabilities. Three systems were used for study. (Author)
