Tailings concrete

Web11 Apr 2024 · For ultra-high strength concrete, the iron tailings had little effect on concrete strength when its content was less than 20%, beyond this content, the strength decreased almost linearly (Zhao et al., 2014). This should be related to both the property of tailings and the microstructure of the interfacial transition zone (Duan et al., 2013 ... WebHerein, we prepared autoclaved lightweight aggregates containing quartz tailings (QT) and determined their effect upon mechanical properties of concrete. QT, by pelletizing and autoclaving, were directly mixed with quicklime, cement and fine river sand to prepare lightweight aggregates, denoted as autoclaved QT aggregate (QTA).
