Fecha de publicación: | mar-2008 | Editor: | Universidad de Antioquia | Citación: | Revista Facultad de Ingeniería 43: 77-85 (2008) | Resumen: | The results obtained in an experimental study that analyzed the hydration process of ordinary Portland cement (OPC) paste with 20% addition of thermally treated kaolin (TTK) are presented. The kaolin was thermally treated between 500 and 900°C. Resulting pastes were analyzed by x-ray diffraction (XRD), differential thermogravimetry (DTG) and scanning electronic microscopy (SEM). After 60 curing days the main phases present in the TTK-cement system were the CSH gel, Gehlenite Hydrated Amorphous (C2ASH8) and Portlandite (CH). The kaolin treatment temperature affects the hydrated system phase composition. | URI: | http://hdl.handle.net/10261/258343 | Identificadores: | issn: 0120-6230 e-issn: 2422-2844 |
