BUBBLE-CONTAINING GYPSUM SLURRY
Provided are a bubble-containing gypsum slurry and a method for producing the same, whereby, in bubble-containing gypsum slurries of the same specific gravity, a bubble size in the gypsum slurry can be increased with a small amount of a foaming component.A bubble-containing gypsum slurry containing, a hydraulic powder containing gypsum, water, the following component (A1), optionally the following component (A2), and the following component (B),component (A1): an alkyl or alkenyl sulfate or a salt thereof,component (A2): one or more selected from surfactants other than component (A1), andcomponent (B): a nonionic compound with a Log P of 0 or more and 3.0 or less,wherein a mass ratio of a content of component (B) to a total content of components (A1) and (A2), (B)/[(A1)+(A2)], is 0.05 or more and 0.5 or less.
