Keywords:Silica fume slurry, Three-Component Cement Concrete, track agitator, surface air permeabilty

It has been reported that the salinity penetration resistance of concrete is greatly improved by using a three-component binder in which silica fume is mixed with blast furnace cement, and its spread is desired in an area where damaged by chloride is severe.We are examining the spread by the method of adding slurryed silica fume with a track agitator.In this experiment, various investigations were conducted for the purpose of grasping the basic properties in the case of adding silica fume slurry with a track agitator.From the experimental results, it was found that even when the silica fume slurry was added by a track agitator, properties similar to those of normal mixing were obtained.
