    Bentonite Clay: Environmental Properties and Applications documents the origin, properties, and characteristics of bentonite and its uses. A resource for researchers, practitioners, regulators, and policy makers, the text examines the use of clay in hazardous waste and nuclear waste management and provides readers with detailed descriptions of. The use of industrial waste as a potential stabilizer of marginal construction materials is cost effective. Phosphogypsum and fly ash are industrial wastes generated in very large quantities and readily available in South Africa. In order to explore the potential stabilization of vastly abundant expansive soil using larger quantity phosphogypsum waste as a potential modifier, composites Cited by: 3.

The main mineral components of bentonite are montmorillonite, quartz, and feldspar. The bentonite used in this study was sodium bentonite and the spacing between its layers was found to be d () = nm. The position of the d () peaks varies for the different types of : Xinhui Zhan, Liping Xiao, Bing Liang.

Surfactant-modified clay minerals are known for their good sorption properties of both organic and inorganic compounds from aqueous solutions. However, the current knowledge regarding the effect of both cationic and nonionic surfactants on the properties of bentonite is still insufficient.
