Real-time monitoring of a structural component gives information on the time and condition at which damage occurs, thereby facilitating the identification of the cause of the damage. Moreover, it enables timely repair, hazard mitigation and study of the damage evolution. This paper reviews the use of electrical resistance measurement to monitor damage in cement-based materials. This method is sensitive to even minor, microscopic and reversible effects. This paper addresses damage due to static/dynamic stress, freezethaw cycling, creep and drying shrinkage, in addition to the effect of strain rate on the damage evolution.
