ResumenThis paper reports on the effect of the temperature used to activate kaolinite-based paper industry waste on the hydration products obtained when the activated waste was mixed with a lime solution. After activation at temperatures ranging from 500 to 700 ºC, clay waste exhibited high pozzolanic activity. Analysis with instrumental techniques such as X-Ray diffraction, differential thermal analysis, infrared spectroscopy and scanning electron microscopy showed that higher temperatures favored the formation of calcium aluminate hydrates, hydrotalcite-like compounds and strätlingite, while at lower temperatures CSH gels constituted the majority hydrated phase. According to these findings, reaction kinetics differed substantially from the results obtained at temperatures of 700-800 ºC, particularly in terms of phase quantity and timing of appearance
