AbstractCement mortars containing 0% and 10% silica fume were prepared with a water/ (cement + silica fume) ratio of 0.60 and 0.70. Sand/cement ratios of 0, 0.5, 1.0, 1.5, 1.8, 2.0, 2.25 and 3.0 were used. Results indicate a large increase in frost resistance for specimens with 10% silica fume plus ( sand)/(cement + silica fume) ratio or >= 2.25 at w/(c +sf) of 0.60, with the greatest resistance for a sand/(cement + silica fume) ratio of 3.0. The improved frost resistance was attributed to the formation of pores in the 97,000--875 nm range at the sand--cement interface.
