The influence of Al3+ions that had been solid dissolved in C-S-H on the amount of Na+ions adsorbed on C-S-H surface was studied. The experimental results show that the solid dissolution of Al3+ions in C-S-H structure makes the electronegative C-S-H surface increase electronegative amounts, that is the reason why the adsorption ability of C-S-H for Na+ions increase.

The single factor variance of viscosity experimental data of blast furnace slag was calculated by Minitab software. The influence of slag basicity and chemical compositions on the slag viscosity was obtained. The results show that there have insignificant effects on the slag viscosity when the slag basicity is over than 1.02, MgO content is less than 11.95% or TiO2 content is less than 12.57%. While the slag basicity can be influenced significantly with the slag basicity less than 1.02, MgO content over than 13.95% and TiO2 content over 13.57%. The Al2O3 content of the slag should be less than 12.75%.

Al doped ZnO thin films（AZO films） was prepared by sol-gel method. The influence of Parameters of different processes on the crystallization properties, micro-morphology and optical properties of this kind of films were studied, using by X-ray diffractometer, filed emission stereoscan, spectral photometer, hall admeasuring apparatus. The results indicated that the crystallization properties, micro-morphology and optical properties of Al doped ZnO films were best on the condition that the sol density was 0.5mol/L, hat treatment temperature is 600 and there is a 8-layer coating.
