Replacement Of Cement In Concrete With Red Mud

Red mud prevents the corrosion of reinforcement and it also acts as a good binding material bavani et al 2018.

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. Red mud compressive strength tensile strength. It has been neutralized by using commercially available hcl to bring down the ph from 10 6 to 8 6. 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.

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. Of the stone powders used marble s showed the best performance in terms of both rheological and mechanical properties. Index terms redmud workability strength properties soroptivity. 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 develop red mud as a partial replacement of cement on concrete by replacing 0 30 percent of the weight of cement by red mud. Cement replacement proved to be capable of improving the mechanical properties of scc. Fresh and hardened properties of 12 scc mixes made with red mud granite marble and limestone waste powders. 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.

The red mud percentage for replacement of of concrete cement is varied as 0 2 4 6 8 10 12 14 16 18 20. 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. Workability of concrete produced by replacing cement by washed red mud is higher as com pared to concrete produced by unwashed red mud. Different researchers utilized the red mud in their studies to increase the strength of concrete and cement based materials and to improve.

One main objective of this work is to study the effects of red mud on properties of m30 grade.
