Abstract This series of four reports present the results of various phases of a project aimed at studying the effectiveness of concrete repairs. In phase 1, a literature search was carried out to identify the state of the art with regard to repair materials, methods for selecting and specifying repairs and measurement of effectiveness of repairs. (The report for phase 2 of the project, which involved selecting the locations and procedures for the investigations of carried out in subsequent phases is not published in this series). In phase 3, 65 locations were visited including coastal, river and inland locations. Elements examined included beams, columns, slabs and walls from structures including bridges, tunnels, power stations and other reinforced concrete frame buildings. Investigations involved the collection of samples, visual inspection and non-destructive testing. Phase 3a involved recovery of core samples and their analysis using several specialist techniques. Finally, phase 4 of the project involved site investigations of repairs, and showed that ineffective repairs occurred primarily where the original causes of deterioration had not been addressed, particularly the continued exposure to water, often containing salt.
