Studies the Environmental, Cosmetic, and Pharmaceutical Applications of Bentonite ClayBentonite clay, of which members of the smectite family of clay minerals are particularly important, has proven to be effective in sealing off wastes from groundwater. Bentonite Clay: Environmental Properties and Applications explores the mineralogy of clays in ge

Roland Pusch received a PhD in soil mechanics in 1962 from the Royal Institute of Technology (KTH), Sweden, and a PhD in geology in 1970 from Stockholm University, Sweden. He was an associate professor in soil mechanics and foundation engineering at Chalmers University of Technology (1967-1974), Sweden, and a professor at the Technical University at Lule 1974-1982), Sweden. Dr. Pusch's academic career was paralleled by work in major consulting companies. The author of five books, including Microstructure of Smectite Clays and Engineering Performance (together with R. N. Yong) for Taylor & Francis, he has also published numerous papers.
