This study seeks to evaluate the possibilities of red mud application in construction industry, focusing into two main areas: cement production/ceramic material and road construction. Red mud based concrete enhance the strength at early ages because of rate hydration is more in the red mud based concrete at an early age. Introduction . 135 0 obj Red Mud: An Overview 3 Aerial view of red mud landfills in the U.S. Current Waste Management and Disposal Practices of RM 1. However, such type of construction has some serious drawbacks such as, i) Water penetration ii) 2. Abstract. 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. Mineralogically, red mud contains phases of undigested alumina, aluminosilicates, and phases of iron and titania. The residual red mud from the above, free from sodium, is used for the production of construction bricks. Red mud from an alumina refinery situated at the eastern coast of India (18°49′9′′N, 82°57′52′′E) was ground to 100 mesh size and used for the study. This material is considered hazardous according to the Environmental Protection Agency (EPA). Every year, millions of tons of this hazardous material is produced around the world. M.Tech - Student, Dept of CE, KIET. uuid:6caf2586-b45d-41f3-b922-543dc3d42cdf Red mud (RM) is generated as a waste material during the production of alumina from bauxite, and it comes to around 40% of the bauxite used for the production. This material is considered hazardous according to the Environmental Protection Agency (EPA). 0. Red mud is the solid waste residue of the digestion of bauxite ores with caustic soda for alumina (Al2O3) production. 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. stream Furthermore, such materials are abundantly available and renewable in nature. Red Mud in Construction Materials General Construction Applications. 136 0 obj Before the end of the decade of the 1980’s red mud became a major concern in world environmental discussions. In this paper the red mud is used as an alternative construction material after remediation by biological process. 1. Varnavas, P.P. Sea Water Discharge RM is transported to sea via pipes. Though the existence of a. lumin. A new project, involving high pressure filtering and dry disposal and reuse of Red Mud, is under implementation. endobj Clay is a healthy solution for modern day building construction. Many researches are still being carried out on the neutralisation of red mud in various ways. A recent literature review conducted by Vijaya et al. 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. Poulos et al., 1996. Depending on the source material and the intended process, a drying step is required prior to additional processing in many settings. Backgrounds from other researchers were taken into consideration and analysed according environmental, economic and technical feasibilities. Red mud is a caustic by-product of the Bayer process of bauxite refining to produce alumina. This gives a cost effective neutralisation method as well as abundant material which can use in construction. Backgrounds from other researchers were taken into consideration and analysed according environmental, economic and technical feasibilities.
