ABSTRACT
Much research has been conducted in the field of concrete durability and a vast amount of repair materials have been developed to improve the durability performance of concrete. These repair materials are highly specialised and are generally highly priced. Although a variety of tests (strength, chemical and electrochemical) are usually conducted on the materials before they are put into production, the long term durability properties of these materials are not well established, in most cases. This investigation work therefore set out to determine the effect that repair materials have on the long term durability of concrete structures.
