This document presents a summary of a student's project on using red mud concrete. The student investigated replacing Portland cement with red mud, a waste product from aluminum production, in concrete. The document outlines that 1-2.5 tons of red mud is created for every ton of alumina produced. Concrete cubes were cast using different percentages of red mud replacement and tested after 28 days, with compressive and tensile strength decreasing as red mud content increased. The conclusion is that red mud concrete is suitable for ornamental works where aesthetics are important.

4. ABSTRACT
 Red Mud is a waste material generated by the
BAYERs process.
 The aim of the present research work was to
investigate the possibility of replacing the
Portland cement by RED MUD.

5. INTRODUCTION
Definition
The insoluble product generated
after Bauxite digestion with Sodium
hydroxide at elevated temperature and
pressure to produce Alumina.

6. MANUFACTURING
1 ton of Alumina is produced from 3tons of
Bauxite and 1ton Alumina is produced from
2tons of Alumina.
Depending on the material processed.
1-2.5 tons of Red Mud is generated per ton
of Alumina produced.

7. PROPERTIES
Physical Properties
1.Generally Fineness of Red mud is
varies between 1000-3000cm2/gm
2.PH varies in between 10.5-12.5.Hence
alkaline in nature
3.Specific gravity is to be 2.51

8. CHEMICAL PROPERTIES
1.In Red concrete the percentage of Cao is
very less.
2.Hence it has no cementitious properties
but it react with water and cement.
3.The percentage of Silica is available

9. MECHANICAL PROPERTIES
Compressive strength
Concrete cubes of 15cm were
casted by replacing cement using
redmud.
after 28 days this cubes are taken
to compression test.

10. Splitting Tensile Strength
Concrete cubes of dia 100mm and
200mm in length were casted by
replacing cement using red mud in
varies percentages.
These cylinders were water cured for 28
days.

11. CONCLUSION
From experimental work it was found that
increase in red mud content decrease the
compressive as well as tensile of concrete.
Concrete prepared by using red mud is
suitable in ornamental works and gives
aesthetically pleasant appearance.
