with CaO, leaching out the useful aluminates for recirculation to the Bayer process, and utilizing the remaining calcium silies in cement manufacture. US3876749A - Method for the reduction treatment of red mud - Google Patents Info
Chloride ions diffuse through the concrete cover and interact with the cement hydration products. As a result, some chloride ions become chemically and/or physically bound. Free chloride ions are the primary cause of steel corrosion in reinforced concrete structures. In this study, ultrasound was used to detect the presence and binding of chloride ions in cement pastes that contained
