A Study on Hardened Properties of Concrete by Using Industrial Wastes as Replacement

Abstract

Red mud is a residue of Bayer’s process during the production of alumina from the Bauxite ore and it gives significant amounts of fine high percentage of alkalinity residue of bauxite. It produces equal quantity of metallurgical alumina and it is disposed in sealed and unsealed bags which lead to an important environment issues. Foundry sand is a fine uniformly sized, clean high quality silica lake sand that is bonded to form a moulds for ferrous and nonferrous metal casting. When these sand has been used for longer time where the sand can no longer be reused in the foundry and it will be treated as waste foundry sand here four test groups were conducted with the replacement percentages of 0%,5%,10% and 15% of cement by red mud and foundry sand of 0%,15%,25%, and 35% by fine aggregates.
