dc.description.abstract	© 2020 Elsevier B.V. To realize the win-win objective of environmental conservation and waste recycling, oil-contaminated soil was utilized as an additive in cement-based materials. The effect of diesel and engine oil and the corresponding oil-contaminated soil on cement-based materials were studied, including the heat release of cement hydration, rheological and flow properties, flexural and compressive strength, hydration products and oil leaching values. The results showed that oil-contaminated soil increased the heat release of hydration of unit mass cement and reduced rheological and flow properties of cement paste and mortars. However, when the dosage of oil-contaminated soil is about 4%, the optimum values of the flexural and compressive strength of mortar, in standard curing 7 and 28 days, were obtained. The leaching values of oil in the disposition satisfied the requirement of China standards. The results confirmed that utilizing an appropriate dosage of oil-contaminated soil in cement-based materials improved the flexural and compressive strength, which is stable to dispose of the waste. This shows that using disposed oil-contaminated soil in cement-based materials will serve as a cost-effective and environmental solution.

Abstract:

© 2020 Elsevier B.V. To realize the win-win objective of environmental conservation and waste recycling, oil-contaminated soil was utilized as an additive in cement-based materials. The effect of diesel and engine oil and the corresponding oil-contaminated soil on cement-based materials were studied, including the heat release of cement hydration, rheological and flow properties, flexural and compressive strength, hydration products and oil leaching values. The results showed that oil-contaminated soil increased the heat release of hydration of unit mass cement and reduced rheological and flow properties of cement paste and mortars. However, when the dosage of oil-contaminated soil is about 4%, the optimum values of the flexural and compressive strength of mortar, in standard curing 7 and 28 days, were obtained. The leaching values of oil in the disposition satisfied the requirement of China standards. The results confirmed that utilizing an appropriate dosage of oil-contaminated soil in cement-based materials improved the flexural and compressive strength, which is stable to dispose of the waste. This shows that using disposed oil-contaminated soil in cement-based materials will serve as a cost-effective and environmental solution.
