Carbon nanotubes/nanofibers were synthesized directly on the particle surfaces (Portland cement, fly ash, sand). Mixing these carbon-modified particles with ordinary Portland cement creates a cementitious binder, where the carbon nanofibers are perfectly dispersed in the volume. Previous attempts to create nano-reinforced composite materials suffered from flocculation and improper dispersion of admixed nanofibers. Now, the hybrid material can be intermixed directly with water creating strong and brittle composite.
