Mechano- electric effect of cement paste was investigated in this paper. As compressive stress was applied on the specimen, an electrical current was observed.
The technology of activation by adding few activators (【1% ) to increase the amount of blends in cement was investigated. The results show that outer activa-ti
The structure around Ti<sup>4+</sup> in BaO-SiO<sub>2</sub>-B<sub>2</sub>O<sub>3</sub>-TiO<sub>2</sub> had been studied by X-ray fluorescence spectra. The resul
