“…Its disposal in hydrologic environment can cause environmental risk due to the mobility of metal ions. These metal ions get mixed in surface water and ground water system, which may be detrimental to human being as well to the environment [1][2][3][4][5][6][7][8][9][10]. Various technologies have been developed which purport to render a waste or to reduce the potential for the release of toxic species into the environment.…”

“…Na Figura 2 é apresentada a curva de solubilidade calculada para Cr(OH) 3 , em função do pH. 5 Estudos realizados por Duchesne e Laforest, 7 com o intuito de verificar o efeito da utilização de diferentes tipos de aditivos ao cimento, mostram uma significativa eficiência quanto ao aprisionamento do metal cromo. Estes autores observaram que os íons cromo são quase que totalmente imobilizados nas fases sólidas hidratadas do cimento, independentemente da razão inicial água:sólido.…”

“…In this technique impurities are blended with cement to obtain desired characteristic in the final product [79]. To control setting characteristic and to provide a chemical or physical environment to check the leaching of toxic containment to the environment a large number of investigations have been performed to determine the effects of various inorganic compounds on physical chemical and engineering properties of cement and cement based binder systems [21, 80,81]. Ordinary Portland cement as well as modified Portland cement using fly ash, lime, slag etc.…”
