A common characteristic of all current masonry ties is that they are made of steel. In wall assemblies, the ties which are embedded in the mortar cross the air space, which contains moisture (water) and air (oxygen), two agents which together cause the corrosion of steel. Glass fibre reinforced composite ties were developed to overcome the problem of corrosion. Part of the development process was to determine the bond strength of the tie in mortared joints in clay brickwork and concrete blockwork. The results ofthese tests are described in this paper.
