Service Life of Concrete Repairs

Abstract Effective repair and protection of concrete structures prolong their service life. This is well documented. There are various repair and protection categories ranging from mechanical repair to electrochemical repairs and surface treatments. The service life of these repairs as such is, however, less studied and documented. There are several parameters that can be used to estimate to what extent the repairs retain their protective properties over time. This paper summarises these parameters and gives a short state of the art review of published English literature over the last 35 years regarding service life of concrete repairs and protection. A call to improve the procedures linked to concrete repair is also presented.
