AbstractAbout AuthorsReferences
It is shown that the introduction of technical carbon (carbon black) in the form of an aqueous dispersion into the composition of fine concrete increases the strength of samples in bending and compression to of 50.25% at the concentration of carbon black of 0.005% by weight of cement. This is due to the compaction of the structure of the cement matrix. The dependence of physical and mechanical properties on the age of carbon black dispersion associated with the aggregation of particles into flake-like formations, leading to an increase in the dispersion consumption is established. The intensification of cement hydration processes confirmed by the results of IR-spectral and differential-thermal analysis is noted. It is established that by the degree of modification of the structure of the cement matrix, the carbon black dispersion is comparable with the carbon nano-tubes dispersions, at that the cost of carbon black dispersion is significantly lower than similar carbon nanostructures.
