| you are: Air izvest
The Limy dough maintain in a hole not less than two weeks. It is impossible to apply the limy dough in which remained not extinguished izvest as its clearing in plaster and a laying will cause rastreskivanie the hardened limy solution.
Depending on a quantity of water, added to komovoj to exhaust, it is possible to receive the limy dough or gidratnuju izvest (pushonku). Clearing to exhaust in pushonku carry out in gidratorah continuous action in which allocated heat and water steams are used for transformation komovoj to exhaust in the most thin friable powder in volume weight 400-450 кгм3. At clearing in pushonku izvest increases in volume in 2-3,5 times; in a greater degree ' raspushivaetsja ' highly active izvest with the high maintenance.
Izvest is applied on building in the form of building solutions, i.e. In a mix with sand and other fillers. On air the limy solution gradually hardens under the influence of two simultaneously proceeding processes: 1) solution drying, rapprochement of crystals and their accretion; 2) karbonizatsija to exhaust under the influence of carbonic gas which in a small amount contains in air.
The Formed carbonate of calcium grows together with crystals and strengthens a limy solution. At karbonizatsii water, therefore plaster and walls in which limy solutions are applied is allocated, subject to drying. Limy solutions harden slowly, drying accelerates their process tverdenija.
