Abstract
Official abstract text for this publication.
The invention provides a thickener for hydraulic composition comprising (A) a water-soluble cellulose ether, (B) a defoamer, and (C) a gum. The thickener is combined with a hydraulic substance, an aggregate and water to form a hydraulic composition.
First claim
Opening claim text (preview).
1 . A thickener for hydraulic composition, comprising (A) a water-soluble cellulose ether, (B) a defoamer, and (C) a gum. 2 . The thickener of claim 1 wherein the gum is selected from the group consisting of diutan gum, welan gum, xanthan gum, and gellan gum. 3 . The thickener of claim 1 wherein the water-soluble cellulose ether is selected from the group consisting of alkyl celluloses, hydroxyalkyl celluloses, and hydroxyalkyl alkyl celluloses. 4 . A one-component water-reducing agent comprising the thickener of claim 1 and (D) a water-reducing agent. 5 . The composition of claim 4 wherein the water-reducing agent is a polycarboxylic acid copolymer and/or a salt thereof. 6 . A method for preparing a hydraulic composition, comprising the step of mixing the one-component water-reducing agent of claim 4 with a hydraulic substance, an aggregate and water.
