GGBFS Activated by Tetra-Isopropyl Titanate
In order to prepare high activated ground granulated blast furnace slag (GGBFS), tetra-isopropyl titanate was used to process GGBFS in this study. Internal standard method of infrared spectroscopy (FT-IR) was used to study the activation extent of GGBFS influenced by the concentration of tetra-isopropyl titanate, activation temperature and time. The FT-IR analyses showed that the extent of GGBFS coupling reaction was the highest, when the accelerating agent was 0.6%, the concentration of tetra-isopropyl titanate, activation temperature, activation time were 1%, 100°C and 30min, respectively. The GGBFS which is activated by tetra-isopropyl titanate remarkable improves the mechanical properties of artificial marble.
