YE Qing (College of Civil Engineering, Zhejiang University of Technology, Hangzhou 310014, China)  
The effect of SiO2 sol (nano-silica) on the mechanical properties and the microstructure of cement-based material was studied using X-ray diffraction, scanning electron microscopy and the method for testing bond strengths of the interface between hardened cement paste and glass surface with a glass slide set into the middle of the square-bar specimen parallel to the bar cross sec- tion. The results indicate that the flexural strengths and the compressive strengths of hardened cement paste and concrete, and the bond strengths of the interface between hardened cement paste and the glass surface all increased with the increase of the SiO2 sol content. When the content of SiO2 sol was over 1.50% the strengths did not increase. With the addition of 1.50% SiO2 sol, incorpo- rating slag as a partial cement replacement and at the age of 28 d, the bond strengths of the interface increased by 40% over that without SiO2 sol, and the flexural strengths and compressive strengths of concrete increased by 20% and 15% respectively over that without SiO2 sol. Furthermore, the crystalline orientation degree, the crystalline size and the content of portlandite at the interface obviously decreased and the interfacial transition zone decreased when SiO2 sol was added. The results suggested that SiO2 sol may be regarded as one of best admixtures for modifying the mechanism properties and interfacial transition zone of high performance cement-based materials.
