Clay is the common name for a number of fine-grained, earthy materials that become plastic when wet. Chemically, clays are hydrous aluminium silicates, usually containing minor amounts of impurities such as potassium, sodium, calcium, magnesium, or iron. Most clays are chemically and structurally analogous to other phyllosilicates but contain varying amounts of water and allow more substitution of their cations. ... a general but important group within the phyllosilicates that contain large percentages of water trapped between their silicate sheets. Publication Date: April 1969. Thermoplastic polyurethane nanocomposites of reactive silicate clays: effects of soft segments on properties Ind. 1. ... Properties. An addition of clay will reduce the flowability of the sand mixture which if ... Properties of sand-silicate mixtures with clays:- DECLARATION I hereby declare that the thesis entitled Synthesis and properties of polymer/layered silicate clay nanocomposites submitted for Ph.
