Perfect adhesion of polymer modified cement mortars (PCC-mortars) on concrete is of vital importance in applications such as repair, flooring, waterproofing or corrosion protection of concrete structures. Suitable adhesion test procedures have therefore to be developed. In this paper the complexity of adhesion testing is discussed. A program of adhesion tests, as used in our R + D laboratories for the development of new mortar products, is presented. It consists of three system tests: a preliminary test for qualitative evaluation of the adhesion and cohesion properties of the mortar on concrete; a test to determine the adhesive tensile strength and the durability of adhesion in low and high humidity environment; and an ageing test in which the adhesive tensile strength behaviour is investigated under cyclic temperature changes of the environment including freezing/thawing with deicing salts. The test performance of epoxy and styreneacrylate modified cement mortars is analysed.
