Water-resistant gypsum material and method for producing the same |
| abstract |
(57) [Abstract] [Object] The present invention provides a water-resistant stone-kou material and a method for producing the same, which is a floor material or wall material that is required to have high strength and a low dissolution rate in water even in a wet state, Further, it is intended to obtain a concrete pouring form efficiently and at low cost. [Constitution] A slurry is prepared by mixing an aqueous solution containing 0.1 to 1% of polyacrylic acid hydrazide with gypsum. An aldehyde or a polyvalent metal ion solution is added to this slurry for pressure dehydration, or the slurry is subjected to pressure dehydration and then immersed in the aldehyde or polyvalent metal ion solution. |
