Abstract

The main task of the presented research was to investigate the carbon
nanotubes, synthesized from aromatic hydrocarbons and as well as to
investigate the possibilities of production and main technological
properties of Portland cement based foam concrete reinforced by
dispersed carbon nanotubes. The method of stimulation of
dehydropolycondensation and carbonization of aromatic hydrocarbons in
chemical active environment (melts of aluminium, copper, nickel, iron
salts) was used for carbon nanotubes synthesis. The results of
investigation of the synthesized carbon nanotubes by X-ray
photoelectron spectroscopy showed that they contain (80 - 90) % of
carbon. The examination of the carbon nanotubes microstructure by
electron microscope have shown that the nanotubes have a cylindric
form, with diameter ranging up to 100 nm and length up to 20 mum. The
nanotubes are agglomerated to fiber shaped agglomerates with a diameter
up to 30 mum and a length up to 10 mm. The carbon nanotubes were used
as a high strength dispersed reinforcement for production of foam
non-autoclave concrete produced on the base of Portland cement. The
results of the investigation of the reinforced non-autoclave cement
foam concrete showed that the use of carbon nanotubes (0.05 % by mass)
in production of these concretes allows to decrease its heat
conductivity up to (12 - 20) % and increase its compressive strength
up to 70 %.
