Concrete is the foremost building material in the region of the sphere and used in operational works, including infrastructure, low and high-rise buildings. Substitution of waste materials will conserve dwindling resources, and will avoid the environmental and ecological damages caused by quarrying and exploitation of the raw materials for making cement. So we are interested in replacement of cement with waste materials coming from oil industry and rice mill industry. So we are taking spent bleach earth (SBE) from oil industry & rice husk ash (RHA) from rice milling industry. W/c ratio as 0.38 and SP 430 IS used for obtaining required slump. The required slump is arrived at 0.7% of admixture. Following replacing the Cement with SBE 5%, 7.5%, 10% and RHA with 2%, 4%, 6%, 8%, 10% aimed at optimum results. Now SBE5% & RHA 8% got optimum values. Subsequently beams, cylinders, cubes are casted. Compressive strength, Split tensile strength, Flexural strength originate for 7 days & 28 days. Later 28 days curing cubes are placed in Hydrochloric acid (HCL) for durability test. For durability test cubes are submerged in 5% of HCL for additional 28days & find the Compression strength.
