Cement mortars containing 0, i0 and 30 percent silica fume were prepared at water/cement + silica fume ratios of 0.45 and 0.60. Compressive strength, Ca(OH) 2 and non-evaporable water contents and pore-size distribution were monitored up to 180 days. Silica fume reacts with most of the Ca(OH) 2 for
The microstructure of the transition zone between steel and cement paste, and the effect of replacing portland cement by two levels of condensed silica fume was studied. Even with a high level of cement replacement (16%), some calcium hydroxide crystals with preferred orientation are formed near the
