Development of a high-performanceconcrete with increased resistance to acids

Concrete for particular requirements

Concretes with increased requirements for resistance to acids are used above all in sewer systems (including agriculture) [1], in certain industrial chemical plants or in the construction of power stations (cooling towers). The use of concretes with increased resistance to acids for the construction of cooling towers thereby currently represents one of the highest demands on the performance of concrete. The cooling water vapours, mixed with exhaust gases, condense on the cooling tower shell. In the 1980s, cooling towers began to be used not just for the cooling of water, but also for discharging exhaust gases. The Modellkraftwerk Völklingen was the first to discharge purified exhaust gases via the cooling tower at the beginning of the 1980s.
