Method for producing gypsum foam and composition for gypsum foam |
| abstract |
(57) [Abstract] [Purpose] To provide a method for producing a novel gypsum foam which is lightweight and has excellent fire resistance. [Structure] Sulfuric acid or its metal salt is added to calcium carbonate, then anhydrous gypsum is added, and the mixture is kneaded with water while foaming due to the carbon dioxide gas generated by the above addition, and then the gypsum is hardened with the by-product gypsum dihydrate. A method for producing a gypsum foam characterized by the following: |
