Effect of Silica Fume on Workability and Water Impermeability of Concrete
A designed experimental study has been conducted to investigate the effect of silica fume on workability and water impermeability of concrete, a large number of experiments have been carried out in this study. The results indicate that the addition of silica fume has adverse effect on the workability of concrete composite. The slump and flowability of the concretes containing silica fume is less than that of the concrete without silica fume, and a considerable decrease for the slump and flow of the concrete was observed by increasing the dosage of silica fume. Besides, the addition of silica fume can improve the water impermeability of the concrete composite evidently, and the water impermeability is becoming better and better as the silica fume content is increasing gradually.
