    Clay - Wikipedia

    Clay is a finely-grained 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 Importance of Clay in Geotechnical Engineering

    Sep 12, 2018  Clay is a very important material in geotechnical engineering, because it is often observed in geotechnical engineering pract. Generally, this soil type has numerous problems due to its low strength, high compressibility and high level of volumetric changes. Clay needs to be improved before it can be used in road construction, dams, slurry walls, airports and waste landfills.
