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).
The invention claimed is: 1. A one-component water-reducing agent comprising a thickener for hydraulic composition, said thickener comprising (A) a water-soluble cellulose ether selected from the group consisting of alkyl celluloses, hydroxyalkyl celluloses, and hydroxyalkyl alkyl celluloses, (B) a defoamer, and (C) a gum selected from the group consisting of diutan gum, welan gum, xanthan gum, and gellan gum; and a water-reducing agent, wherein said water-reducing agent is a polycarboxylic acid copolymer and/or a salt thereof. 2. A method for preparing a hydraulic composition, comprising the step of mixing the one-component water-reducing agent of claim 1 with a hydraulic substance, an aggregate and water.
