Solidification/Stabilization of Lead Contaminated Soil Using Magnesia Phosphate cement and Ordinary Portland cement
Background and objectives: Solidification/stabilization is an effective technique for reducing the leachability of contaminants in soils. Magnesia phosphate cement and ordinary Portland cement can be used to remediate soils contaminated. In this study, the performance of the solidified/stabilized soil was compared for mixtures composed of magnesia phosphate and ordinary Portland cement. Materia...
متن کاملStabilization/solidification of Iron Ore Mine Tailings Using Cement, Lime and Fly Ash
Current research emphasis is more on the utilization of materials that are considered as waste. Tailings and fly ash are major category of industrial wastes, whose disposal is problematic from environmental point of view. In this present research, Industrial byproducts, namely, lime (CaO) and class F type fly ash have been used as candidate materials along with the partial addition of ordinary ...
متن کاملSolidification–stabilization of organic and inorganic contaminants using portland cement: a literature review
The treatment of hazardous wastes using cement-based solidification–stabilization (S–S) is of increasing importance as an option for remediating contaminated sites. Indeed, among the various treatment techniques, S–S is one of the most widely used methods for treating inorganic wastes. To enhance the application of S–S and to further develop this technology for site remediation, particularly fo...
متن کاملPreventing acid mine drainage from mine tailings
Mining activity always has high impact on its surroundings, being waste deposition the cause of multiple and complex problems to the environment. One of them is Acid Mine Drainage (AMD), causing acid water percolation through large areas in the mine site. Portugal was a prosper tungsten producer from the beginning of the XX century, having its apogee during World War II. Nowadays there are mill...
متن کاملSolidification of Sodium Bearing Waste Using Hydroceramic and Portland Cement Binders
AM-S19-39 A hydroceramic is a monolithic solid produced by a hydration driven reaction that occurs after mixing metakaolin with concentrated NaOH solution. The chemistry of the starting materials is optimized to encourage the formation of tectosilicates (zeolites, feldspathoids) during curing. Furthermore, the process is forgiving enough so that a variety of caustic waste streams can be accommo...
