Method for preventing deterioration of hardened cement |
| abstract |
PURPOSE: To nearly perfectly prevent the deterioration of the hardened cement in a long period of time by impregnating an aq. treating liquid contg. an alkaline (earth) metal nitrite of a molten state and an org. silicone compd. of a dissolved state into the hardened cement and then drying the same. n CONSTITUTION: The aq. treating liquid (B) contg. the component (a) of the molten state, the component of the dissolved state or the component (ii) of the dissolved state or emulsion state is obtd. by compounding (a) 1 to 50wt.% alkaline (earth) metal nitrite (e.g. calcium nitrite), (b) 0.01 to 20wt.% org. silicone compd. expressed by (i) formula (M is Na, K: R is 1 to 12C monovalent hydrocarbon group) (e.g. sodium methyl siliconate) or polymer of the org. silicone compd. expressed by the formula and (c) water. The component B is impregnated from the surface into the hardened cement (A) contg. a corrosive metallic material or aggregate which induces an alkaline aggregate reaction and is then dried. n COPYRIGHT: (C)1990,JPO&Japio |
