A Fumed Silica slurry when added to concrete stops pores at 0.1 Milli Micron providing significantly faster attained strength and corrosion resistance.  Concrete can also be slip formed higher, faster with less surface finishing. Significantly increased compressive strength, being typically doubled, reduced pore content and diameter for more efficient freeze-thaw protection,  reduced chloride permeability for reduced salt scaling.  Improved rate of strength attainment, i.e. fast early strength, 3 days not 28 days, with  reduced shrinkage rates and reduced water uptake potential.  Increased electrical resistivity for reduced corrosion reduced pore volumes for freeze-thaw protection without compromising water resistance, all of which indicate improved durability particularly in harsh environments.
