Dispersion of High Concentrations of Carbon Nanofibers in Portland Cement Mortars

Figure 1

Percent passing graph showing the grain size distributions for OPC, microfine cement, and silica fume. The microfine cement has a mostly uniform grain size distribution in the same size range as silica fume, and all grains are smaller than those found in the OPC. The Blaine fineness of the OPC and the microfine cement is ~350 m2/kg and >12,000 m2/kg, respectively.
