Abstract:
Despite the 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. To achieve lasting repairs, the properties of the repair material and substrate must be properly matched. This paper first discusses the failure types frequently encountered in patching, and the repair types used to rehabilitate structures. Then, a comprehensive list of the relevant material and structural characteristics that should be considered in the design of durable repairs and the selection of compatible patching materials is described.
