Abstract
One environmental risk associated with the use and reuse of materials for construction purpose is the potential release and migration of contaminants from the material into the surrounding environment. Leaching tests were conducted on mortar containing oily and salty materials (Oil up to 10% by sand mass, saline water up to 226660 mg/L) generated from petroleum process to examine the effectiveness of cement-based mortar as a stabilisation/solidification method. The leachability data showed that although the chemical oxygen demand (from encapsulated oil) from 28-day mortar had increased with the increased oil content, the performance of all mortar mixes had successfully immobilised the oil content to be landfilled. By contrast, others displayed their suitability to be used in the construction industry subject to particular acceptance criteria. Furthermore, although there was variability in the 28-day leachate conductivity, it was not significantly different from the control. This suggests that the dissolved salt ions were successfully trapped within the solid matrix and that the Portland cement (PC) had good binding ability.
