Description |
Repair and rehabilitation of deteriorated concrete structures are essential not only to
utilize them for their intended service life, but also to assure the safety and
serviceability of the associated components. A good repair improves the function and
performance of the structure, thus prevents ingress of aggressive species to the
steel/concrete interface and improves its durability. It is important to evaluate the
performance of repair materials available for repairing the deteriorated concrete
structures. This investigation was carried out to evaluate the durability characteristics of
five types of modified cement based repair mortars. The corrosion resistance of the
repair materials was evaluated by conducting various tests such as water absorption,
rapid chloride ion penetration test, impressed voltage, 90 days ponding test, macro cell
corrosion test, weight loss measurement, etc. Details of the test and their results were
discussed. It is concluded that the modified cement based repair mortars formulated
with different mineral admixtures (fly ash and/or silica fume) showed improved
corrosion resistance.
