Abstract

Carbon nanofiber (CNF)/clinker hybrid material was prepared by a direct synthesis of CNFs on the surface of clinker particles in a fluidized bed reactor using acetylene and carbon dioxide gases at the temperature of 550 °C. This allowed us to achieve a good dispersion of CNFs in a clinker matrix and to prepare strong mortar composite. Optimal concentration of the CNFs to enhance mechanical properties of the mortar was found to be around 0.4%, which led to more than 2.5-fold increase in the compressive strength.
