Abstract : The durability of concrete repairs depends to a large extent on the proper selection and application of repair materials. Restrained contraction of repair materiais, the restraint being provided through bond to the extsting concrete substrate, is a major factor which significantly increases the complexity of repair projects as compared to new construction. Preliminary performance criteria for dimensionally compatible repair materials were developed based on a state-of-the-art review of the literature on cement-based repair materials. These preliminary criteria are intended for screening and selecting cement-based materials for concrete surface repairs. A comprehensive experimental program of laboratory and field tests was developed to verify the performance criteria. (MM)
