PURPOSE:To prevent the weathering of hydraulic calcium aluminate by adding fatty acids to the hydraulic calcium aluminate. CONSTITUTION:Fatty acids are added to hydraulic calcium aluminate preferably by 0.001-3 pts.wt. per 100 pts.wt. hydraulic calcium aluminate and they are mixed and pulverized. Hydraulic calcium aluminate produced by this method has improved weathering resistance and can be stored over a long period of time after premixing with an admixture of various refractories, gypsum, calcium sulfoaluminate, etc. |
