Investigating the protective properties of concrete containing ash from coal combustion in a fluidized bed

The article reports the results of research on the protective properties of concrete with the addition of ash from hard coal combustion in a fluidized bed at a power plant in Katowice. Research was carried out on concentrated water extracts from disintegrated concrete using a polarization technique. The results were compared with those obtained in a similar way from concrete extracts without additives and with criteria including the delimiting values of the parameters of the electrochemical process. The results have shown that concrete incorporating 15% and 30% ash as cement replacement correctly protect reinforcement against corrosion.
