| Date Issued | 15 June 2021 |
| Abstract | Sludge disposal is a major environmental issue, especially those containing heavy metals. This has led to the development of various disposal techniques to comply with the environmental standards. One technology for sludge treatment is the solidification-stabilization process. Solidification is the process of transforming the material into a solid manageable form, and stabilization is to prevent the migration of hazardous chemicals of the material into the environment. In this study, several mixtures of cement and admixtures were prepared and mixed with electro-plating sludge containing nickel, copper and silver. Effect of cement + sludge with and without admixtures were observed in the compression test of concrete cylinders under different curing periods. The Toxicity Characteristics Leaching Procedure (TCLP) was undertaken to determine leaching resistance to heavy metals. Infrared Analysis and X-ray diffraction analysis was used to determine the development of hydration of the different cement mixtures. Scanning electron microscopy data showed development of the cement with admixtures with the control. The study shows that cement together with additives is effective in retarding leaching of heavy metals from the cement-sludge mixture after solidification-stabilization. The addition of admixtures in cement further helped in the solidification-stabilization process by attaining the required compression strength and leaching resistance of the S/S mixture. |
