ABSTRACT:
When bentonite clays and portland cements are mixed with aqueous solutions or with mixtures containing polluting materials, a solid mass is formed. The quantities of bentonite and cement control the consolidation of materials and govern physical factors, such as the hardness and the chemical characteristics of the resultant material. This resulting product is chemically and physically stable; a solidified product which is almost completely insoluble in water, and in which, pollutants are encapsulated in the matrix so that the waste material is rendered non-polluting and fit for ultimate disposal.
