Chemical composition of red mud is Al2O3 (16–17.5%), Fe2O3 (53.5–56%), SiO2 (6-7%), TiO2 (5-6%), Na2O (4-5%), and CaO (2-3%). 2014-01-18T08:12:18Z 5) Varnavas, P.P. E-mail: Student, Dept. Red mud is an industrial waste which is being generated by Bayer process of alumina production. Red mud is a caustic by-product of the Bayer process of bauxite refining to produce alumina. of Texas Rio Grande Valley, Edinburg, TX 78539. In order to manage this industrial waste, several researches have been conducted to investigate the possibility of utilizing red mud as a useful construction material. Approximately 35–40% of the processed bauxite ore goes into the waste as alkaline red mud slurry which consists of 15–40% solids and 0.8–1.5 tons of red mud is … Red mud, construction material, interlocking blocks, industrial waste. of Civil Engineering, Univ. A recent memorandum between UC Rusal and Chalco covered joint R&D projects, including a focus on the red mud problem. Although recycling of red mud is being actively researched, a feasible technological solution has not been found yet. The model footing test has been performed in laboratory under different conditions (dry and partially saturated) to check the suitability of red mud as a pavement subgrade construction material. The common red clay used for the production of tiles is the most abundantly available mineral, with high plasticity and workability in wet condition. stream However, such type of construction has some serious drawbacks such as, i) Water penetration ii) Prof, Dept of CE, KIET. 0. This paper focuses on a critical review on the utilization of red mud as a road material in pavements, including using red mud in road bases and asphalt mixtures. 1. Furthermore, such materials are abundantly available and renewable in nature. 5) 136 0 obj Red mud is a solid waste product of the Bayer process, the principal industrial means of refining bauxite in order to provide alumina as raw material for the electrolysis of aluminum by the Hall-Heroult Process. Uses of Red Mud as a Construction Material 0 Like. 2.Lagooning RM is left in clay-lined landfills. red mud for construction or building material production is a economic way to prevent hazardous impact of solid waste coming from alumina processing plants. Nitro Pro 7 (7. In 1980, Barsherike studied the possibility and rationality of producing cement with red mud as the raw material Use of red mud cement not only reduces the energy consumption of cement production but also improves the early strength of cement and resistance to sulfate attack. In order to manage this industrial waste, several researches have been conducted to investigate the possibility of utilizing red mud as a useful construction material. fibreless mud brick, because, fibres are strong against stresses. materials. China has a target to recycle 10% of all of its red mud, and Chalco has already introduced several solutions to recover iron and rare earth metals from red mud waste, so the residues can be used for steel and concrete production. It is generally dumped near the plant in a pond without any usage, occupying costly land. Results showed that red mud can be used for those purposes. of Civil Engineering, Univ. looked at some of the more... Use in Porous Asphalt. In this paper the red mud is used as an alternative construction material after remediation by biological process. endstream 2014-01-18T08:12:18Z 1. A new project, involving high pressure filtering and dry disposal and reuse of Red Mud, is under implementation. Red mud is the solid waste residue of the digestion of bauxite ores with caustic soda for alumina (Al2O3) production. CHARACTERIZATION OF RED MUD AS A CONSTRUCTION MATERIAL USING BIOREMEDIATION P MEHAR LAVANYA 1*, K SUMANTH KUMAR 2* 1. The residual red mud from the above, free from sodium, is used for the production of construction bricks. It is the eco- friendly building material available on earth. Red Mud in Construction Materials General Construction Applications. The main aim of this work was to determine the dependence of the emanation factor of red mud firing temperature and some other parameters. A recent study looked at the replacement of limestone powder with red mud in porous asphalt. This material is considered hazardous according to the Environmental Protection Agency (EPA). application/pdf Poulos et al., 1996. Red Mud: An Overview 3 Aerial view of red mud landfills in the U.S. Current Waste Management and Disposal Practices of RM 1. Every year, millions of tons of this hazardous material is produced around the world. This paper presents a review of some of the previous studies conducted on the effective utilization of red mud in construction processes. 2.
