Abstract
Cement mortars containing 0, 10 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] formed during hydration within 28 days and improves the compressive strength of the mortar. In addition it affects the pore-size distribution of mortars by reacting with Ca(OH)[2] formed around the sand grains and also with that dispersed throughout the cement paste.
