The research aims to find an alternative to expensive and environmentally damaging cement in the construction industry by investigating the impact of incorporating waste engine oil (WEO) and fly ash (FA) on the engineering properties of green and hardened concrete. The study found that the addition of FA and WEO improved properties such as workability, air content, and porosity, but adversely affected compressive strength. The optimum content of FA and WEO was found to be 40% and 0.5%, respectively, with the least decline in compressive strength. The proposed modification also diminished segregation, bleeding, and the effect of freeze-thaw cycles. This research has significant implications for the construction industry and the environment. By finding a viable alternative to cement, it could potentially reduce the demand for cement and subsequently decrease the carbon emissions produced during its production. The use of waste materials such as WEO and FA can also help reduce waste and provide a more sustainable solution for the construction industry. The findings of this research could inspire further investigation into the use of alternative materials in the construction industry to mitigate its environmental impact.
