According to a study by Sun (Sun, 2013; Wang et al., 2013), when the retorting temperature exceeds 500 °C, the clay minerals in the organic-rich shale (such as kaolinite) will begin to pyrolyze, and the layered structure of the clay minerals will deteriorate, resulting in a ...
Structured marine clay is commonly encountered in offshore engineering projects and engineers are concerned about its impact on the engineering properties of marine clay as well as its correlation with index properties. Current research has emphasized the role of soil structure in these aspects of mari...
(Fig. 1.9). Not all soils are aggregated by biological agents; for heavily weathered Oxisols with kaolinite-oxide clays, there seems to be no hierarchy of organization below 20 µm, because only physicochemical forces predominate there (Oades and Waters, 1991). Studies in our Horseshoe Bend ...

Al4Si4O10(OH)8 (kaolinite) Silicic acids H2Si2O5; H2Si14O29 Layered double hydroxides (LDHs), also known as anionic clays, form a unique class of host materials for intercalation. These clays are anion-exchangers and occur naturally: many new synthetic examples have also been prepared. The...
The most common of these are the clay minerals such as kaolin, kaolinite, attapulgite, bentonite, sepiolite, polygarskite, montmorillonite, illite, chlorite, and plastic ball clays, silica, silica-alumina, alumina, magnesia, zirconia, titania, thoria, beryllia, asbestos, pumice, firebrick and ...
0.8 mg of a partially hydrolysed polyacrylamide (degree of hydrolysis: 20%, average molecular weight: above 107) is added, as a 0.1% aqueous solution, to a suspension of 400 mg of technical kaolinite, 50 mg of quartz powder (particle size: below 10 μm) and 650 mg of activated bentonite...
