摘要： A porous particulate material for treating a fluid containing a contaminant is disclosed. The particulate material comprises a cementitious matrix or binder and treated bauxite refinery residue or red mud. At least a portion of the pores in the particulate material is open cell or interconnected pores. The invention also relates to the use of a reactive permeable barrier comprising porous material, for treating a contaminated fluid. Also disclosed is a method for producing porous particulate material for treating a contaminated fluid and a method for treating a contaminated fluid, in which the porous material is used. The invention furthermore relates to a cementitious composition comprising partially neutralised red mud and cement, wherein the partially neutralised red mud has been pre-treated by contacting it with water having a total hardness supplied by calcium, magnesium or a combination thereof, of at least 3.5 millimoles per litre calcium carbonate equivalent. The cementitious composition is useful as a building and construction material.

摘要： The invention provides compositions comprising bauxite refinery residues that have been reacted with sufficient calcium and magnesium ions that they have a reaction pH of less than 10.5, and one or more water treating additives. The invention also provides processes for treatment of water containing dissolved inorganic substances involving stepwise treatment of the water in which the reacted bauxite refinery residues are added after the addition of a pH-raising additive. The invention also provides processes for treatment of water containing dissolved inorganic substances in which the reacted bauxite refinery residues are added stepwise, with one or more water treating additives also being added in at least one of the steps. The invention also provides a process for the neutralisation of bauxite refinery residue by reacting it with a base amount and a treating amount of calcium ions and a base amount and a treating amount of magnesium ions for a time sufficient to produce an at least partially-neutralized residue exhibiting a reaction pH of less than 10.5.
