Material comprising water-soluble polymer and dried sand or silicates

摘要: A non-cementitious, non-asphaltic material comprises dried sand or silicates mixed with a water-soluble polymer. The polymer may be polyvinyl and is preferably acetate (acetate-versatate) copolymer. also selected from styrene maleic anhydride polymer, hydroxymethyl cellulose, hydroxyethyl 2-butanedioic acid methoxyethene styrene-butadiene coppolymer. composition comprise herbicide and/or fungicide, crystalline sodium silicate, colourant dye, kiln sand. method of stabilising paving blocks using the including step applying water to surrounding claimed. Further claimed comprising specified amounts sand, powdered copolymer kaolin filler PVA colloid protector, herbicide/fungicide silicate.
