ABSTRACT
Concrete sewage systems can be severely damaged when attacked by biogenic sulfuric acid corrosion. While minor aggressive exposures can be accounted by using a high sulfate resistant cement, higher concentrations of acid (pH 3.5) require the protection of concrete surfaces. (Kampen et al. 2011) A number of different linings and coatings have been used in sewage systems throughout the decades (Orlowsky et al. 2010), such as Polymer Concrete (PC) and or manually applied ceramics and inorganic glass. However, these have been limited to newly constructed pipes and manholes as well as local repair.
