“…Also it has been established that in design age adhesion strength is approximately 27% higher if using the mortar modified by silica sol than if using the modifier represented by KNO3 electrolyte. The obtained data are in accordance with the works [18][19][20][21][22][23][24] explaining the influence of such kind of substances on the hardening process.…”

The area of the research is geoconstruction and geostructures in transport. The present study provides modified repair mortars characterized by high penetrating performance, which is important in geoconstruction and transport. Penetrating repair mortars increase compression strength by 1-3 classes, water-resistance by 4-10 atm of the operated concrete geofoundation. Modified repair mortars are of increased crack resistance, they are carbon dioxide and magnesia corrosion resistant material and also they are characterized by high adhesion strength to a concrete geofoundation, which creates a monolithic character of both a restored foundation and a repair geocomposition.

“…Considering the character of these nanoparticles, they can affect the hydration of mineral concrete components. Because of high reactivity, aqueous dispersions of silica nanoparticles can react with ingredients and newly formed phases in hardening concrete mixture [11][12][13][14][15][16]. The use of reactive aggregate should increase the density and strength of the composite, and grant the concrete with unique properties (improved deformation and durability properties).…”

Artificial stone has been one of the most common materials in construction for a long time by now. Despite the variety of types of concrete, the composite is in constant motion of development and improvement. The common use of high strength composite is for the construction of high-rise buildings or projects complex in geometry.This article suggests preparing high-strength cementitious composites by complex chemical activation using chemical admixtures in combination with reactive aggregates, as they give good hydration (hardening) of concrete. Research results confirm that this practice of complex chemical activation of cement gives high-strength concrete with better strength, deformation and durability properties.

“…The "stone sponge", e.g. foam concrete, has these properties and reactions in it are named lithosynthesis [1][2][3][4][5][6]. There are 4 lithosynthesis requirements to be met: an artificial stone of mineral nature; over 5% porosity of the stone; capillary absorption of the solution; the reaction between heavy metal ions and the stone substances with formation of new substances having a very low solubility product (SP).…”

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
