“…where λint , λextheat emission coefficients of internal and external surfaces of a structure, W/(m 2 The results of the research, which are in accordance with the ideas in the works [18][19][20][21][22] makes it possible to claim that preservation levels with GEP from 80,4 and higher meet the requirements of the geoenvironment protection. Preservation levels with GEP lower than 80,4 don't keep the natural environment productive for the life of people generations.…”

The area of the research is natural geosystem preservation in geoconstruction. The aim of the research is introduction of information assessment of preservaton level using total geoecological parameter in geoconstruction. Three features were chosen as the main geoecological information features of the estimate, prediction and geosystem preservation management, they are: natural raw materials consumption, fuel consumption and useful properties of a mineral geostructure with the end of the life-cycle. Rating method is suggested as a method of the rasearch;it includes conversion of the properties, using certain mathimatical operations into dimensionless values named index of properties. By determining weight factors with the help of expert assessment and bydetermining the sum of productions of indices and coefficients as total geoecological parameter, the study shows the relationship of the latter with the values of the real consumption of natural raw materials, fuel and useful properties of wastes with the end of the life-cycle of a geostructure. Also the study suggests the achieved levels of the preservation and predicted increase of the level takinginto consideration the total geoecological parameter. The results can be used for estimate of any geotechnology in the preservation aspect.

“…The works on concrete article surface modification and heavy metal ion soil detoxification unite the mechanisms of reactions SiO2•nH2O studied by Russian school of academician V.B. Aleskovsky [14][15][16][17][18][19][20][21][22]. In accordance with these works, it can be assumed that the processes of SiO2•nH2O interaction are controlled by the value of solubility product, SP, at the initial act of interaction represented by sorption.…”

The paper deals with soling technologies in civil engineering and environmental protection. The object of the interest is silica sol coating, which is formed when a concrete article gets hard in silica sol solution, as well as the sediments of silica sol soil detoxification. The main aim of the research is physical and chemical specificities of soling process. The methods of the study are electronic microscope scanning, x-ray analysis, derivatographic and chemical analysis. It has been found that in silica sol technology, layers of new phases are formed on the surface of cement concrete articles, e.g. calcium hydrates. The depth of the layers has been established. The nature of silica gel after heavy metal soil detoxification has been determined. The prospects of new sol-gel technologies are discussed.

“…Papers [13][14][15] investigate pores and capillaries of a surface and consider properties of an inorganic surface as the object of the impact. According to proceedings [16][17][18][19][20] the reactions start in active places of surfaces and then the development of the process takes place in pores and capillaries. The artificial phosphate building stone was obtained when using clay polluted by heavy metal ions and oil products in the reactions with H3PO4.…”

Lithosynthesis in transport construction for geosphere protection

et al. 2018

View full text Add to dashboard Cite

Geoecological problems of lithosphere protection in transport construction are of great importance nowadays. The article deals with the research of the new lithosynthesis technology which can be used for geosphere protection in transport construction. Lithosynthesis is a new method of geosphere purification by means of engineering structures and building materials. The main aim of the paper is to show a possibility to restore lithosphere using mineral artificial stones of different nature, e.g. foam concrete or phosphates. Both theoretical, namely thermodynamic, method and experimental one are used in the study. Two techniques of lithosynthesis are demonstrated in the paper. The first technique is to apply so-called the "stone sponge" to absorb pollutions and detoxicate them. The second technique is formation of the artificial phosphate stone to detoxicate pollutions during hardening. The level of concentration of heavy metal ions to be detoxicated by means of foam concrete lithoreactions is determined. The study suggests creation of a new lock surface, e.g. through sols' use, after detoxication of pollutions. * Corresponding author: lbsvatovskaya@yandex.ru , 0 (2018) https://doi.org/10.1051/matecconf /201823901005 MATEC Web of Conferences 2018 TransSiberia 239 1005
