DURABILITY OF REPAIR MATERIALS

Abstract

Despite the widespread and expanding need for concrete repair, the lack of comprehensive data and suitable guidelines leaves designers with some uncertainty as to how to proceed with the design and execution of durable repairs. The extreme climatic conditions in North America make it even more difficult. One of the most widely used methods of repair is the patch and waterproof procedure involving cementitious or polymeric patches and elastomeric membranes. This article presents an overview of material and structural characteristics and other factors that should be considered in the design of the repair process and the selection of patching materials.
