“…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.

“…The research proves that hardness of foam concrete increases up to 50% that is why reliability of the "stone sponge" is raised after detoxication. 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.…”

Lithosynthesis in transport construction for geosphere protection

et al. 2018

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

The paper deals with technologies of a mineral material surface improvement for transport construction. Mineral surface is important because of its hardness, durability and other properties. Besides, it is necessary to protect it from aggressive environment. The purpose of the article is to introduce a few techniques of silica sol use in order to change mineral surface properties. The absorption, irrigation and watering processes were applied as the techniques. Both silica sol and its mixes with solutions contained Ca(II) ions were used as the substances. The experimental methods were carried out during the study. The experiment results have shown that hardness of the mineral material and foam concrete surface was increased up to 60% and the level of the soil strengthening was more than 0,5 MPa. It means that if silica sol and solutions containing Ca(II) ions are used a soil strength is increased more than 40-50%. The results of the study are particularly useful for construction of motorways in order to extend their service life.
