Abstract: Red mud is a solid waste of industrial aluminum production Bayer process from bauxite ore. The Bayer process is the most widely used method, accounting for 95% of alumina production. Some norms classify red mud as toxic and dangerous material for the environment, due to its chemical composition. The chemical composition varies a lot depending on the origin and type of bauxite as well raw materials, methods of obtaining aluminum and methods of disposal. Its disposal represents a significant environmental problem. Furthermore, alumina production has significantly increased Worldwide. As its disposal is a problem, many studies have been developed in finding the utilization of red mud in some branch of industry. Different strategies for managing red mud have been developed in the past period. For instance, this solid waste may be transformed into useful products, such as adsorbents, or can be used for neutralization, of for revegetation. Also, it can be very useful in ceramic production etc. By exploitation of this solid waste material the aluminum industry would practically reduce waste to a minimum. Mass uses, such as building materials, can consume large volumes of red mud in an environmentally safe way. This paper presents the possibility of red mud use in civil engineering i.e. for building materials - concrete and cement. The possibilities of using red mud from landfill in Podgorica (Montenegro) in building materials are presented in this paper.
