Applying Study on the Bayer Red Mud as Fast Building Dam Materials

In China, the soaring red mud needs outdoor place for stockpiling. The traditional building method of tailing dam is often construction dam only once, which needs the biggish piling up yard or quantities of dam. The construction-dam technology of “three-dimensional seepage drainage stack” was proposed, combining stereoscopic drainage discharging separated water and rainwater, geogrid reinforcement minishing fissured development and enhancing dam stability, and air dry in turn. Using bayer red mud to build dam quickly comes true. The experiment of the method was carried on and makes some conclusions through testing strength indexes: after depositing bayer red mud 4~5m heights continuously, and the ten-days air-curing drying, red-mud strength indices have been improved greatly and it can be used to damming. The way of “three-dimensional seepage drainage stack” makes good use of waste materials，reduces the yard space, saves the red mud rolling or compaction equipment, economizes the constructed cost of the dam. The process provides some references in the field of the bayer red mud as quick damming material in the practice.
