Waterproof covers a surface of building materials so-called

The building materials base of silicate and sulphate connecting in an outcome of interaction with atmosphere swallow a moisture. There for their partial destruction in a cold season in an outcome of the extension of freezing water happens. For an elemination of this process it is necessary to produce covers, which do not pass and do not swallow a moisture. Other major request presented to these covers, is the availability and low cost. In construction one of major problems is the guard of metal constructions from corrosion. As has shown the analysis and our researches by such materials for covers can be phosphatic materials. They are well combined from a various kind by oxides, both natural and tecnological of an origin. In case of use tecnological of raw material, for example of oxides of iron formed in metallurgical productions, the ecological problem of deleting from a nature of polluting substances is decided also. Phospphatic connecting can be derivated because of low-grade ortho-phosphoric of an acid or phosphate of some productions, being scraps [l]. The materials are named phosphatic, which in the cement of role is executed by salts orthophosphoric acids formed during chemical interaction it with components of an initial mixture. (with) >Ortho-phosphoric an acid or it metallophosphatic (phosphatic connecting) are main and necessary products for production materials of phosphatic formed because of of processes of acidicmain interaction. In this class the connecting phosphoric acid exhibits the most interesting properties by virtue of features of an electronic structure of phosphonun which is included in it structure, and it of ability to organize inorganic polymeric structures. The processes causing harding phosphatic of masses, are complicated, are individual for each structure and are investigated few more. On a course of processes the decisive influence renders bases of substances which are included in the powder of cement, acidity of a liquid base, temperature. Ability phosphatic knitting to organize stable composite communication(connection) between separate component of a material is adjusted by application of oxides various bases, modification of concentration ortho-phosphoric of an acid, heat to temperatures ensuring shaping of ceramic-similar phases, not subject hidrotation [2]. By ancestor of significant number phosphatic connecting, known now, were alumphosphatic connecting, representing metastable solutions phosphates of aluminium. Their synthesis is reduced to dissolution in ortho-phosphoric to an acid of the 65%-s' concentration of a required(demanded) amount of aluminium hidrocead. Time of dissolution 15-20 min, temperature about 100' C. Ready connecting is viscosity a transparent solution [3]. For want of heating phosphatic connecting the rather complicated processes happen, however, in all a temperature interval (1 500 'C) formed those or others crystalline and aMopQHbie of a phase reliably execute a role of cement. A final product of thermal transformations amoMo~oc@aTHoro of connecting any structure is AlP04. Being crystallochamistry by analog of crystal, this junction undergoes polymorphic transformations similar to the transformations Si02. However, if polimorfic of transformation of crystal are accompanied by significant modifications of volume, that can result in destruction of silicate items, the AlP04 extension, called(caused) by similar transitions, less noticeably and not so drastically influences a falling of strength phosphatic of a material. Because of phosphate connecting the various kinds of highly effective water-resistant and heat resisting materi-
