Abstract
- This research study shows for the first time the hydration reaction of Activated Art Paper Sludge (AAPS)-lime mixtures cured at 20°C. Two mixtures series were prepared using weight ratios of 3:1 and 1:1 for AAPS/lime. The kinetics of the hydration reaction was investigated by characterization techniques such as X-ray diffraction, thermo-gravimetrical and differential thermal analysis, 27Al and 29Si {1H} magic angle spinning nuclear magnetic resonance. Results show higher quantity of hydrated phases formed with the increase of the AAPS/lime ratio (such as calcium silicates hydrates (C–S–H), hydrated tetracalcium monocarboaluminate , and hydrotalcite-like phases), specially C–S–H exhibiting a major incorporation of Al3+ into silicate chains, increasing its medium chain length. It becomes demonstrated that mechanical performance of the studied mixtures will be directly influenced by all these parameters. [ABSTRACT FROM AUTHOR]
