Investigating Workability and Mechanical Properties of Concrete using Binary and Ternary Blends of Red Mud and Silica Fume with M-Sand

Concrete technology frequently employs cement alternatives. Even though there is numerous research that have examined the properties of concrete with addition of mineral admixtures. In order to determine the best way to use these materials, such as red mud (RM) and silica fume (SF) with manufactured sand (M-sand) at the ages of 7, 14 and 28 days; this study contrasts the binary and ternary cementitious systems of workability and mechanical characteristics (compressive, flexural and split tensile strength). Twelve different mix proportions were produced in the form of a binary and ternary blended cementitious system, with red mud and silica fume changed from 0-20% with an increment of 5%. The designated test result will be added for admixtures minerals, which will generally affect the properties of mechanical and workability of all tested specimens. Red mud is less effective than silica fume, though. In addition, compared to the alternative experiments, the combined use of red mud and silica fume concrete mix marginally increases the mechanical qualities. It is concluded that the usage of supplementary cementitious materials with mineral admixtures increases strength enhancements upto 10% replacement of red mud and silica fume.
