SELECTING DURABLE REPAIR MATERIALS: PERFORMANCE CRITERIA

It has been known for over 50 years that cement material possesses an unrelenting tendency toward volumetric changes (shrinking and cracking). The cracking phenomenon of cement-based materials is fairly well understood today. Yet, the profusion of cracking in old and new concrete structures, and especially in concrete repairs, continues to be observed. The objective of repair is to produce a durable, rehabilitated structure with a limited and predictable degree of change without deterioration or distress throughout its intended service life and purpose. Selection of a repair material for a particular use is one of the critical steps in achieving a durable repaired structure. Design, construction practices, and quality control are also important. This article, the first of two, presents the results of a study carried out on the parameters affecting the durability and serviceability of concrete repairs.
