Abstract: A high opacity, defined kaolin clay product having a relatively narrow particle size distribution, low colloidal particle content and an average particle surface area of less than about 30 square meters per gram is prepared by defining an aqueous kaolin clay slurry via controlled centrifugation to remove a substantial portion of the colloidal particles therein. Prior to being subjected to centrifugation, the aqueous kaolin clay slurry is prepared so as to improve the defining process achieved via centrifugation by first subjecting the aqueous kaolin clay suspension to scrub grinding so as to break up agglomerates into individual kaolin clay particles without substantial delamination of the kaolin clay particles.

Abstract: Conventionally, paints which are formulated for use as markings on roads have also been used as markings on airport runways but have been found unsatisfactory since airport runway markings have special requirements. The present invention provides a super-high opacity thin coat concept airport runway markinng paint comprising 25-75% by weight of titanium dioxide in the paint, extenders such as Barium Sulphate, Laminar Talc, Calcite or Dolomite used alone or as blends thereof, binders such as Plasticized Chlorinated Rubber, Acrylated rubber, Epoxy, Polyurethane or emulsified resins and an anti-skid aggregate comprising crushed glass particles or calcined Aluminum oxide or the like. Airport runway markings need frequent maintenance re-application of paint in order to obliterate the black markings left after contact with aircraft tires.

Abstract: A low density aggregate product and method for making the same utilizing coal ash slag resulting from a typical coal gasification system wherein the resulting aggregate product has a lower density than the initial coal ash slag. The coal ash slag is combined with a small amount of a binder and then fired for a predetermined time and temperature to produce the aggregate. Also, by heating the coal ash slag and binder, a gaseous efflux is emitted to form interlaced channels throughout the aggregate which have a characteristic length and diameter.
