Abstract: The Bayer Process is the method used for the production of alumina from Bauxite ore is characterized by low energy efficiency and it results in the production of significant amounts of dust-like, high alkalinity bauxite residues known as red mud. Currently red mud is produced almost at equal mass ratio to metallurgical alumina and is disposed into sealed or unsealed artificial impoundments like landfills, leading to important environmental issues. Based on economics as well as environmental related issues, enormous efforts have been done worldwide towards management red mud in utilization, storage and disposal. In the project an effort is made to assess the strength characteristics of the aluminum red mud as partial replacement for cement in concrete. Specimens were made by adding the red mud as replacement for cement in percentages from 0 % to 60 % at an internal of 10 %. To enhances the binding properties hydrated lime of 5 % is added to the mix.
