FIELD: production of colorfast jointing materials.
SUBSTANCE: the invention is pertaining to the colorfast jointing materials, in particular, to a hydraulic binding substance and to a paste, from which it is possible to make such materials, and to the method of production of such materials. The colorfast jointing material is formed from the sources of calcium aluminate, calcium silicate, calcium sulfate and reactive silicon dioxide. At that the ingredients are present at such relative ratios, that at a hydration would be formed both a monosulfate (C3A.CS.12H) and a hydrated aluminum oxide(AH3). The invention also presents the hydraulic binding substance and the paste, using which it is possible to form such materials, and the method of formation of such materials. The technical result of the invention is the weak discoloration of the materials, preservation of the satisfactory physical properties, especially - a good positive stability to the natural weather environment.
EFFECT: the invention ensures the weak discoloration of the materials, preservation of the satisfactory physical properties, good positive stability to the natural weather environment.
