Replacement Of Cement In Concrete With Red Mud

The red mud used for the replacement of cement is brought from steel industry obtained by bayer s process the characteristics of red mud depend on the nature of the bauxite ore used.

Replacement of cement in concrete with red mud.

Compressive strength of concrete produced by replacing cement by washed red mud goes on increasing upto 8 replacement of cement by washed red mud and reaches peak at 8. The test results show that how its compressive strength splitting tensile strength decreases with increase red mud content it is concluded that optimum percentage of the replacement of cement. To study the effect on workability and strength properties of concrete mix with varying percentage of cement replacement by red mud. Of the stone powders used marble s showed the best performance in terms of both rheological and mechanical properties.

It has been neutralized by using commercially available hcl to bring down the ph from 10 6 to 8 6. One main objective of this work is to study the effects of red mud on properties of m30 grade. By taking cementatious behavior of the red mud into account an experiment was carried out to partially replace the cement by red mud in concrete for different percentages and also its effects on the strength and other properties of the concrete. The red mud percentage for replacement of of concrete cement is varied as 0 2 4 6 8 10 12 14 16 18 20.

Red mud prevents the corrosion of reinforcement and it also acts as a good binding material bavani et al 2018. Therefore it can be used as a partial replacement of cement in mortar and concrete. Index terms redmud workability strength properties soroptivity. 4 the decrease in initial setting time at 5 and 10 may be due to the light weight of neutralized red mud and finer particles of mud which fills the voids of the cement by which there may be increase in the density of the mix.

Workability of concrete may get affected with increase of red mud but it can be improved by adding superplastcizers. Fresh and hardened properties of 12 scc mixes made with red mud granite marble and limestone waste powders. Concrete produced by replacing cement by unwashed red mud and when subjected to alternative wetting and drying for 50 cycles goes on increasing up to 10 replacement levels anandakumar et al 2015 steel slag are also the waste generated material from the manufacturing of steel industry. Red mud compressive strength tensile strength.

Different researchers utilized the red mud in their studies to increase the strength of concrete and cement based materials and to improve.
