| 要旨 |
The filler effect of volcanic glass powder (VGP) was investigated in this study by using Thermogravimetry analysis (TG), X-ray diffraction/Rietveld analysis (XRD), and selective dissolution method. Experimental results showed that VGP has a great acceleration behavior on the hydration degree of individual clinkers in the VGP-OPC system except for the Belite phase. The effective water to cement ratio had no effect on the hydration at the early age in the VGP-OPC system. The acceleration of hydration was caused by the additional nucleation sites provided by the VGP particles. |
