Document Type and Number:
WIPO Patent Application WO/2023/182047
Kind Code:
A1
Abstract:
Provided are a cell-containing gypsum slurry and a manufacturing method therefor that make it possible to increase the cell diameter in a gypsum slurry with a smaller amount of a foaming component, with a gypsum slurry containing cells and of the same specific gravity. The cell-containing gypsum slurry contains: a hydraulic powder including gypsum; water; an (A1) component below; optionally an (A2) component below; and a (B) component below. A mass ratio (B)/[(A1)+(A2)] of the content of the (B) component and a total content of the (A1) component and the (A2) component is 0.05 to 0.5 inclusive. (A1) component: Alkyl or alkenyl sulfate ester, or salts thereof
(A2) component: One or more selected from surfactants other than (A1) component
(B) component: A non-ionic compound with LogP of 0 to 3.0 inclusive
