Influence of Na2Si2O5 on the Hydration of C4AF with Various Surface Areas
The hydration of C 4 AF having various surface areas was investigated with Na 2 Si 2 O 5 solution. The hydration behavior of C 4 AF depended on the amount of silicate ions precipitated on its surface. The amount of precipitated silicate ions, which hindered the hydration of C 4 AF, was proportional to the surface area of C 4 AF. The precipitated silicate ions on the surface of C 4 AF were founded to be a silica-like material by means of X-ray photoelectron spectroscopy (XPS). They formed a layer approximately 3 nm thick on the surface of C 4 AF.
