Abstract | Full Text

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. Betono su skysto kuro krosnyje sudegintos anglies pelenais apsauginių savybių tyrimas Santrauka Straipsnyje pateikti betono su Katowice gamykloje skysto kuro krosnyje sudegintos anglies pelenais apsauginių savybių tyrimų rezultatai. Taikant poliarizacijos technologiją buvo tiriamas vandens koncentratas, išskirtas iš suirusio betono. Rezultatai palyginti su panašių tyrimų rezultatais, kai taikant tokią pačią technologiją buvo tiriamas betonas be priemaišų. Rezultatai taip pat buvo palyginti pagal kriterijus, ivertinančius ribines elektrocheminio proceso parametrų reikšmes. Rezultatai parodė, kad, betone 15 ar 30 proc. cemento pakeitus pelenais, armatūra būna tinkamai apsaugota nuo korozijos.
