Optimization of synthesizing bricks from red mud composite with coconut fiber and clay

Abstract Red Mud is a bauxite solid waste which dangerous for the environment because of its alkalinity (10-13). With very high pH, it can interfere with hydrological conditions areas that are directly affected by mud. Efforts to utilize red mud have use-value been widely carried out. consists Gibbsite, Hematite and Cristobalite. The main ingredients Fe 2 O 3 , Al SiO still be utilized 44.66%, 28.87% 20.21%. as basic material bricks. needs composited other materials does not enough composition get good quality For this reason, in study, was composed clay coconut fiber. Both these known content compared In optimal mud, clay, fiber ash compositions 3: 1.
