substitute in order to explore the qualities of concrete. The Bayer Process, used to make alumina from bauxite ore, is notable for its low energy efficiency and for producing large volumes of red mud, or dust-like bauxite leftovers with high levels of alkalinity.
Red mud disposal expenses are between 1 and 2 percent of the cost of alumina. Red mud's cementatious behaviour was taken into consideration when an experiment was conducted to partially substitute cement with red mud in concrete at varying percentages. Its effects on the reinforcement of other concrete qualities were also examined.
Along with several other minor components, it is made up of iron, titanium, aluminium, and silica oxides. Red mud's presence of alumina and iron oxide makes up for limestone's lack of those substances, which is the main raw material used to make cement. Globally, significant efforts have been made to address red mud management challenges, including usage, storage, and disposal. These efforts are motivated by economic as well as environmentalrelated concerns.
1.1 Advantages of Using Red Mud in Concrete Environmental improvement: Industrial waste may replace 30% of the cement used in construction operations worldwide, reducing carbon dioxide emissions by up to 320 million tonnes. The issue of not having enough land to deposit the trash will be solved by substituting industrial waste in concreting methods, and ground water contamination can also be managed.
Experiments have been conducted under laboratory condition to assess the strength characteristics of the aluminum red mud. The project work focuses on the suitability of red mud obtained for construction. Four test groups were constituted with the replacement percentages 0%, 5%, 10%, 15%, with cement in each series M35 grade concrete. This paper points out another promising direction for the proper utilization of red mud.
Key Words:
Improving soil quality: As civil engineers, our first concern should be employing environmentally friendly, sustainable materials that have the necessary structural strength. The problems with land storage will be overcome, and the quality of the neighbouring soil will significantly improve, if we employ red mud waste in the production of concrete.

1. INTRODUCTION
Reduction in the Energy Requirements for the Production of Ordinary Portland Cement: One tonne of cement requires between 1.6 and 1.9 tonnes of raw materials. The majority of industrial waste is composed of pozzolanic, limestone, and clay components. Red mud and fly ash are examples of industrial waste that may be used properly to save natural resources and reduce resource use. Additionally, it would save energy use and provide concrete constructions the necessary strength.
Due to industrialization and urbanisation, cement output has more than quadrupled globally during the previous 15 years. In 2015, it is anticipated that production of aluminium would increase to around 50 million tonnes. The Bayer process uses bauxite ore to produce more than 95% of the alumina that is produced worldwide. Red mud, which is a substantial volume of dust-like, highly alkaline bauxite leftovers, is produced by Bayer's alumina manufacturing process. One of the greatest industrial byproducts in contemporary civilization, its estimated worldwide inventory reached 3000 million tonnes at the end of 2010, and it is increasing by roughly 120 million tonnes annually. The chemical and minerological makeup of bauxite residue is
