Abstract : The constant increase in rate of cement in developing countries such as India has aroused the need to relate research to production. This Paper deals with subject of reducing the overall construction cost of concrete by partial replacement of Pozzolanic Portland Cement(PPC) with an optimum content of sawdust to reduce the cost and addition of Lathe Scrap Powder (LSP) to compensate the loss of strength due to replacement of cement by sawdust. PPC was replaced with 6%, 8%, 10%, 12% and 15% of sawdust to find the optimum percentage. LSP was then added in 0.25%, 0.5%, 0.75%, 1.0% and 1.5% to the sawdust concrete. After a time period of 7 days, 14 days and 28 days curing of standard size concrete cubes a compressive strength test was carried out, and the slump test was done on freshly prepared sample of concrete. Weight of the cubes was also found to calculate the bulk density of the steel incorporated sawdust concrete. Results show that on addition of 0.25% LSP on sawdust concrete indicated compressive strength (31.33) which was comparable to that of plain concrete(32.66).
