Abstract

Official abstract text for this publication.

The present invention is a hydraulic composition, which includes an α-hydroxy sulfonic acid or a salt thereof, a hydraulic powder and water, wherein the ratio of slag in the hydraulic powder is 60% by mass or more.

First claim

Opening claim text (preview).

The invention claimed is: 1. A hydraulic composition comprising an α-hydroxy sulfonic acid or a salt thereof, hydraulic powder and water, a ratio of slag in the hydraulic powder being 60% by mass or more. 2. The hydraulic composition according to claim 1 , wherein the α-hydroxyl sulfonic acid or the salt thereof is contained in an amount of 0.0005 parts by mass or more and 1.000 part by mass or less relative to 100 parts by mass of the hydraulic powder. 3. The hydraulic composition according to claim 1 , wherein a ratio of cement in the hydraulic powder is 35% by mass or less. 4. The hydraulic composition according to claim 1 , further comprising alkanolamine. 5. The hydraulic composition according to claim 4 , wherein alkanolamine is contained in an amount of 0.0005 parts by mass or more and 1.000 part by mass or less relative to 100 parts by mass of the hydraulic powder. 6. The hydraulic composition according to claim 1 , further comprising an aromatic compound having a hydroxyl group. 7. The hydraulic composition according to claim 6 , wherein the aromatic compound having the hydroxyl group is contained in an amount of 0.0005 parts by mass or more and 1.000 part by mass or less relative to 100 parts by mass of the hydraulic powder. 8. The hydraulic composition according to claim 1 , wherein the α-hydroxy sulfonic acid or the salt thereof is one or more kinds of compounds selected from hydroxymethanesulfonate, 1,2-dihyroxypropane-2-sulfonic acid, and salts thereof. 9. A method of producing a hydraulic composition comprising adding an α -hydroxy sulfonic acid or a salt thereof to hydraulic powder and kneading with water, wherein a ratio of slag in the hydraulic powder is 60% by mass or more.
