“…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.…”

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.

A novel type of flame-retardant decorated plywood (FDP) was designed and prepared based on one kind of intumescent flame-retardant adhesive. The flame-retardant adhesive was composed of the phosphorous-nitrogen flame retardant and melamine urea formaldehyde (MUF) resin. An adhesive was placed between the plywood substrate and the decorative veneer. The shear strength of the FDP satisfied the Class II (GB/T 9846) when the ratio of flame-retardant and MUF was less than 0.65. The thermal stability of the flame-retardant adhesive was measured by thermogravimetric analysis (TGA). The intumescent behaviors of adhesives were systematically investigated. The morphological and chemical structures of the intumescent char of the flame-retardant adhesive were characterized by the scanning electron microscopy (SEM) and Fourier transform infrared spectra (FTIR), respectively. The fire performance of FDP was assessed by the cone calorimeter and the single burning item test. The FDP exhibited the most effective barrier when the optimized ratio of ammonium polyphosphate (APP) and pentaerythritol (PER) in the adhesive is 3. The flame-retardant class of FDP could be up to class B1(B) according to GB/T 8624.
