Among them: Cement Production (including clinkers, composite cements, and alkali-activated cements). A study aimed at using the coarse bauxite residue in road base material found that when modified with a specific pozzolanic-stabilized mixture (PSM) of fly ash and lime kiln dust, the material actually provided an improved road base over that of conventional materials. The property of this material is very different from the ones which are in used in modern day construction hence the method of using it is very different. As they are made from natural materials they are a sustainable, recyclable, non-toxic and healthy form of building construction. What's not to like about a type of construction that gives you an excuse to play in the mud while doing something worthwhile? or you’re not sure where to start, we can help. And although more research is needed, if the barriers to reuse can be overcome, the construction industry would provide a much-needed outlet for the utilization of red mud in significant quantities.

One area of focus has been the application of red mud in the construction industry. Based on the radionuclide concentration, red mud is not permitted to be used directly as a building material, however, mixing of a maximum 20% red mud and 80% clay meets the requirements. Issues which are restricting use of red mud in building and construction have been discussed. Due to the characteristics of fine particles, high alkalinity (pH 10–12.5) and trace metal content, the disposal of large quantities of red mud has caused serious environmental problems including soil contamination, groundwater pollution and fine particles’ suspension in the sea.

Among them: Another literature review examined studies focusing on the use of red mud in ceramic products and summarized that researchers have discovered a number of benefits to this potential application, including the potential to decrease sintering temperatures and reduce energy requirements, and also to improve the resistance of ceramic materials. The red mud project is one of two initiatives the NWA has embarked upon in a bid to find alternative and cheaper materials to be used in road construction. The country, one of the world’s largest bauxite producers, has long struggled with management of the waste. century, log construction became the building technique of choice. Earth as mud bricks, has been used inbuilding construction for thousands of years and approximately 30% of the world’s present population still live in earthen shelters [1]. As mining is an energy-intensive endeavor, the benefits would be further compounded by the savings in energy. Mud is among the most popular building materials in many countries where Heifer works. However, the desirable practices have not been placed on a firm footing due to sporadic nature of the constructions. Burnt clay bricks can be readily manufactured in Ghana as all ten regions have significant clay deposits with the Ashanti region having the highest estimated deposit of 37.1 million metric tonnes. Mud is plentiful and literally dirt cheap, and so is the sunshine used to dry mud bricks until they’re solid enough for construction.
