摘要：
Characteristics of sulfate resistant cement pastes containing limestone as well as silica fume cured lip to 90 days were studied. The results show that the addition of 5 wt. % of limestone as well as silica fume to the above cement improve its mechanical properties as well as give a lower porosity at 3-90 days curing tunes. In addition, the free lime contents give lover values (2.4 and 0.91 wt.%) in the pastes containing 8 and 10 wt.% silica fume, respectively.
