Effect of Silica Fume on Dry Shrinkage and Freezing-thawing Durability of Concrete

摘要：

　　An experimental study has been conducted to investigate the effect of silica fume on shrinkage and freezing-thawing durability of concrete,a large number of tests have been carried out in this study.The results indicate that the addition of silica fume has adverse effect on the dry shrinkage property of concrete.The dry shrinkage strain of the concrete containing silica fume is more than that of the concrete without silica fume,and a considerable increase for the dry shrinkage strain of the concrete was observed by increasing the dosage of silica fume.However,the addition of silica fume can improve the freezing-thawing durability of the concrete evidently,and the freezing-thawing durability is becoming better and better as the silica fume content is increasing gradually.
