It is pointed out that according to the existing opinions of foreign scientists (such as Powers, Ramachandran, Feldman, Swenson and Sereda), the mechanism of carbonation shrinkage of cement stone is considered as a topochemical process and consists in dilution of calcium hydroxide at the points of contact of crystals and formation of additional bonds during the precipitation of reaction products in new zones. The mechanism of the shrinkage of autoclaved aerated concrete during carbonation processes is explained in the framework of the scientific theories of Russian scientists E.S. Silayenkov and E.N. Chernyshov. This mechanism is classified as heterogeneous reaction, referring to its kinetic and diffusion component, where the main causes of shrinkage deformations are the intrinsic stresses of the crystalline intergrowth and the polymerization of silica gel, resulting from the interaction of hydrated calcium silicate with carbonic acid.","PeriodicalId":103378,"journal":{"name":"Proceedings of the International Symposium \"Engineering and Earth Sciences: Applied and Fundamental Research\" dedicated to the 85th anniversary of H.I.

Their traditional production technology involves the use of cementing component, obtained by the mixed grinding of unhydrated lime and silica materials. Nowadays, one of the main tasks is to reduce the production energy intensity of variously-functional wall composites through the use of unconventional, including manmad, raw materials. From this perspective, non-traditional for the construction industry clay rocks of the unfinished minerogenesis stage, are of particular interest. To stabilize clay rocks, complex methods can be used, in which, as a rule, several additives are used, which effect on the rock can be different. It has been established that the use of aluminosilicate binder, including lime (Portland cement) for the production of non-autoclaved silicate wall materials based on non-traditional clay rocks, will contribute to achieving the necessary level of structure formation and maximum physical and mechanical properties of high-performance highvoid wall products under non-autoclaved conditions.","PeriodicalId":103378,"journal":{"name":"Proceedings of the International Symposium \"Engineering and Earth Sciences: Applied and Fundamental Research\" dedicated to the 85th anniversary of H.I.

Analysing these habitats enables to discover the chorological nature of the researched flora, determine dominating geoelements, which provides the basis for, first, correcting the schemes of biogeographic zoning, as well as solving the issues, related with the history of flora. Upper-alpine rock-scree plants of Central and Eastern Caucasus belong to caucasian-holarctic-irano-turanian. The head part of the geographical range corresponds with the sequence of families Apiaceae – Cyperaceae – Poaceae, sequence of geni – Campanula – Carex – Ranunculus and Minuartia. It follows from the above said that the studied flora does not contain tertiary relicts, although ancient species, which may date as far back as the tertiary, exist. These include all ferns and gymnosperms, evergreen bush Rhododendron caucasicum, evergreen shrubs Vaccinium vitis-idaea, Empetrum caucasicum, Daphne glomerata, wintergreen subshrub Dryas caucasica. Also, there are no xerothermic relicts, as in highlands there are no arid areas where the remains of xerophiles could survive. In terms of xerothermic relicts, they can include only one species Cirsium cephalotes, transcaucasian-asiatic species, having within the researched region a relict area up the river Baksan.","PeriodicalId":103378,"journal":{"name":"Proceedings of the International Symposium \"Engineering and Earth Sciences: Applied and Fundamental Research\" dedicated to the 85th anniversary of H.I.
