Hydrodinamic Way of Dispergation of Multilayer Carbon Nanotubes at Modification of Mineral Binders
Keywords:
multilayer carbon nanotube, surfactant, mineral matrix, morphologyAbstract
The possibility of using carbon nanostructures to improve the cement and gypsum composition and improve its physical and mechanical properties was studied. GraphistrengthTM nanotubes produced by Arkema corporation were used as modifying agents. The nanotubes were dispersed in water on a hydrodynamic installation with use of surface-active reagents. It was noted that the flexing strength of concrete increased by 45 %, compression strength - 35 %, ultimate compressive strength of gypsum - 46 %.References
