Oil spills, leakage and other releases of products from petroleum industry are a source of contamination and are recognised as a major environmental concern. The current treatment technologies for these materials are either cost prohibitive and/or the treated products have to be sent to land fill without any potential end-use, thereby rendering these solutions unsustainable. Cement-based stabilisation/solidification is an emerging technology; however there is currently quite limited knowledge on the effect of oil on the cement solidification process and its consequent effect on the performance of fresh and hardened properties of the resultant cementitious mix. The purpose of conducting this study is to determine the appropriateness of the mortar for various end-uses when incorporating mineral oil additions up to 10% of the aggregate mass. Increased oil content in the cement mortar was found to increase setting time and decrease air content. The compressive strength decreased by 78% compared to the control at 28 days age. However, since the compressive strength covered a wide range of values, various feasible end-use scenarios for oil contaminated mortar exist. © 2013 Taylor & Francis Group.
