clay silt content

  • Test for Silt Content in Sand

    V1 – Volume of silt layer V2 – Volume of sand layer. For example, for a given sand sample, if V1 comes out to be 9 and V2 is 130, the % silt content would be 6.9 %. The permissible value of silt content in Sand is 8%, hence the sand sample is ok and can be used for construction purposes. Observation table

    So-called 'clay' soils are not clay. The proportion of clay mineral flakes ( 2 mm size) in a fine soil affects its current state, particularly its tendency to swell and shrink with changes in water content. The degree of plasticity related to the clay content is called the activityof the soil. Activity= I P / (% clay .

  • 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.
