A blend of carbon soot and PET bottle waste was prepared in molten state. Carbon soot was added at a percentage of 0%, 5%, 10%, 15%, 20%, 25% and 30% to the molten PET waste and were cooled and crushed into the required size of fine aggregate. Tests on fine aggregates were performed to examine the effect of carbon addition with various percentage to PET waste. Specific gravity, water absorption, grading, bulking and bulk density test results were obtained for the above samples and also for natural sand to perform comparative analysis. The results of each sample were compared and analyzed with the result of natural sand to determine the most feasible percentage of addition of soot carbon in the PET bottle waste. It was found that an optimum of 10% soot carbon filled PET fine aggregate gave similar results to that of natural sand and better results than that of 0% carbon added PET waste fine aggregate.
