Abstract:
Polymeric surface protection systems can he a durable and potent method to lower the moisture content of the concrete and to improve its durability by inhibiting the penetration of aggressive substances through the surface as well as by limiting the corrosion rates. At the Institute for Building Materials Research in Aachen, ibac, in cooperation with BAM in Berlin comparative tests have been carried out on the long-term durability of selected classes of surface protection systems financed by the German Ministry of Transport. These systems were weathered naturally at two different locations in Germany as well as artificially in different climatic test facilities. Afterwards the mass and dimension changes of the polymeric films, adhesion strength, diffusion of chlorides and carbon dioxide, cross-cut and crack bridging behaviour have been investigated.
