摘要：Excellent flowability is one of the important characteristics of concrete for easier handling and placing and it facilitates the removal of undesirable air voids by introducing superplasticizer (SP). But due to environmental issue related to the waste during SP production, alternatives being initiate to incorporate used engine oil (UEO) that has the same function as SP. It was reported that UEO resulted in improving some concrete properties therefore can lead to counter problems of higher SP cost and UEO disposal. The principal aim of this research mainly to identify the effectiveness of UEO in durability improvement of concrete. Investigation of porosity, chloride penetration and high elevated temperature exposure was conducted. From the result obtained, UEO decrease the concrete porosity and comparable with SP. The result of chloride penetration showed that incorporation of 0.5% of UEO did not cause any adverse effect as compared to the control mix, which meant that UEO could improve the concrete durability. Elevated temperature exposure test was conducted and the percentage strength loss of concrete with UEO was almost similar to the mix with SP. It can be stated that UEO performed very good in durability improvement and comparable with SP.
