In the present research regularities of influence of modification additives on technological and operational properties
of polymer binders are presented. The nano-modification of two different kinds of binders for polymer
composite reinforcement – epoxy and hybrid (organic-inorganic) binders, led to a sensible rise of major performance
features as strength, adhesion, thermal resistance at ultra-low loading of modifying agent – carbon
nanoparticles. At the same time, the regularities of nano-modification display in the extremal dependences.
Keywords: polymer composite reinforcement, epoxy binders,
hybrid organic-inorganic binders, nano-modification, compression

This paper investigates the development of arc discharge ARCD technique in order to synthesis thermally stable CNTs. The method consists initially of the
removal of fullerenes and soluble impurities, followed by liquid-phase oxidation of amorphous carbon. Then, an acid treatment to remove the unprotected
metallic particles was finally affected. The results showed that the purified CNTs sample is thermally stable up to 645oC. The thermal stability of CNTs
depends on the defects on the side walls and impurities in the purified sample and it can be attributed to efficient cooling system used in the apparatus.
Keywords: multiwalled, carbon nanotubes, surfactant, dispersion,
technology, concrete, a cement matrix, a microstructure.

In 1993 the German family company “KNAUF” purchased a share package of the Thermo-Insulating and Gypsum Materials Complex near Moscow. From this time the history of the company «KNAUF» in Russia began. However, scientific and business relations between the company and the Russian scientific community started to take shape in the 1970s, when the regular exchange of experience with leading research institutes was established, and in the end of 1970 the representative office of “KNAUF Engineering” Co. was open.
