Abstract

|
| A novel modular test setup has been developed to provide rapid and simultaneous evaluation of different antifouling strategies. Biofouling tests were carried out on two distinct types of building material: solid white concrete and autoclaved aerated concrete (AAC). The algae species used were Chlorella vuigaris. Both traditional and innovative surface treatments were evaluated for their effectiveness in preventing algal fouling on white architectural and autoclaved aerated concrete. The roughness was evaluated by distance measurements using the automated laser measurement system (AIM). Algae from combinations of water repellents and biocides appeared the most effective treatments for the prevention of algal fouling on concrete with a high bioreceptivity. The algaecidal activity observed on the Ti02 coated samples was promising because the Ti02 based photocatalytic degradation of algae was driven only by the UV light present in a fluorescent light which was periodically switched off. |
