In this paper, the hydration mechanism of portland cement pastes with limestone, quartz and natural pozzolan (80/20 weight) was analized. The techniques used were nonevaporable water content, pozzolanic activity and X-ray diffraction. Results show that filler effect increases initially the amount of hydration products in all pastes. For limestone pastes, the dilution effect is significant at long time, for quartz and pozzolan pastes the dilution effect was lower due to the contribution of the pozzolanic reaction.En el presente trabajo se analizó el mecanismo de hidratación de pastas de cemento portland normal con la incorporación de caliza, cuarzo y puzolana natural (proporción 80/20 en peso), por medio de la evaluación del contenido de agu...
