Clay is a finelygrained natural rock or soil material that combines one or more clay minerals with possible traces of quartz (SiO 2), metal oxides (Al 2 O 3, MgO etc.) and organic matter. Geologic clay deposits are mostly composed of phyllosilicate minerals containing variable amounts of water trapped in the mineral structure.
The clayreinforced epoxy nanocomposite was prepared by the polymerization method. The effect of clay addition on the mechanical properties of epoxy/clay nanocomposites was studied through tensile, flexural, impact strength, and fracture toughness tests. The morphology and tribology behavior of epoxy/clay nanocomposites were determined by Xray diffraction (XRD) and wear test, respectively ...

Preparing clay for pottery is a bit time consuming but ensures your finished project will be successful. Being patient and following a few steps makes clay easy to manipulate and ready to use. When clay is properly wedged and free of air bubbles, firing finished products will have positive results.
Bentonite usually forms from weathering of volcanic ash, most often in the presence of water. However, the term bentonite, as well as a similar clay called tonstein, has been used to describe clay beds of uncertain origin. For industrial purposes, two main classes of .
Lime–calcined clay pastes were prepared using a liquid/solid ratio of to ensure suitable rheology of the paste and a calcium hydroxide/pozzolan ratio of 2/3. A N NaOH was used for paste preparation instead of pure water, to accelerate the pozzolanic reaction by alkali dissolution of reactive phases.
