A method and apparatus for producing a cement-based material, such as concrete, mortar and/or grout reinforced by unidirectionally oriented pre-dispersed alumina nanofibers, as well as the resulting material. The aforesaid process is well suited for industrial-scale production of the cement-based composite materials. The resulting nanomaterial is composed of the cement base, various additives and homogeneously dispersed uniformly oriented reinforcing alumina nanofibers. In various embodiments, the aforesaid composite material may be manufactured by means of water-dispersion of the alumina nanofibers and combining the resulting dispersed nanofiber solution with the cement base and, if applicable, one or more additives. Additionally or alternatively, the alumina nanofibers with or without the cement base may be subject to mechanical or/and ultrasound coarse dispersing. Finally, the resulting nanocomposite material is subjected to the conventional fabrication techniques to manufacture the final composite product. |
