Maintenance and Repair of Concrete and Masonry Structures: Epoxy Pressure Grouting.
Abstract
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 characterisitcs 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. Field studies led to personal evaluation of equipment and techniques as well as to physical evaluation of depth of penetration and effectiveness of repair. Laboratory studies led to curves providing an estimate of flow rate of a grout within a given crack width as a function of grout viscosity. A Guide for Pressure Grouting Cracked Concrete and Masonry Structures with Epoxy Resins was prepared. (Author-PL)
