TESTING AND MIXED DESIGN PROCEDURE OF PARTIAL REPLACEMENT OF CEMENT BY REDMUD UNDER CURING OF IN ORGANIC SUBSTANCES

Civil Engineering

The several different materials were used in the field of civil engineering. At present there are many construction materials available in the construction field. This huge amount of industrial by-products or wastes is generating a huge amount of resources which are unutilized. This research is aimed at finding out usage of such industrial byproducts such as Red Mud. Red mud waste material generated by the Bayer Process widely used to produce alumina Bauxite throughout the world. The study included reinforced concrete beams by the partial replacement of OPC with red mud and to notice the effects of acid, base and salt conditions was discussed in this paper. This paper describes the effect addition of red mud in concrete. Because of storing issue, the waste negatively affects the environment. In this research work red mud is replaced the OPC at different proportions such as 5 %, 10%, 15% and 20 %.a and also we have analyzed the physical and chemical properties of red mud in order to find the strength parameters such as compressive strength, flexural strength of reinforced concrete beam and durability aspects. Beams were cured in three types of solutions which was involved HCL (acid), NAOH (base) &NACL (salt). The effect of adding different percentages of red mud as additional material to concrete mixes on their compressive strength, resistance to sulfates, acid, base and salt were studied. The results were obtained and compared with controlled M25 grade concrete. Red mud blended mixes shown poor results against HCl attack and observed greater resistance against NaCl and NaOH attack.
