摘要：Rapid industrialization in the world leads to the maximum discharge of waste products which in turncausing the effects and hazards to environment. In this project work red mud waste is partially replaced with cementand the strength and durability parameters are evaluated by utilizing it in a best way. Red Mud is a waste generated bythe aluminum industry in a Bayer’s process Availability of raw material required for manufacturing of cement andproduction of concrete are less and require more energy for production. This increased demand cause fast depletion inresources. To overcome this situation it is very important to utilize the industrial waste materials and by-products forthe manufacture of cement and in concrete construction. Here in this work by considering the cementations behaviourof red mud, an experiment was carried out to replace the Portland Cement by red mud and hydrated lime for M20 gradeof concrete for variable percentages and also there effects on the strength. Present study is mainly focused on thecompressive strength, split tensile strength, flexural strength. However, when used in combination with 30% red mud,cement and 5% lime the composites shows significant compressive strength of 27.3N/mm2 for M20. Tensile strength of2.60 N/mm2 for M20 grade of concrete. Selected combination of mix is later used to produce beam of size 500 x 100 x100mm. These beams are tested for flexural strength of results 2.4 N/mm2and 3.29 N/mm2for M20. From this study it isrevealed that 30% replacement of red mud along with 5% hydrated lime is found to be optimum.
