Resumen

This paper presents the main scientific and technical aspects of a pozzolans blend (activated paper sludge (APS) and fly ash (FA)) and its influence on the ternary cement behaviour. Due to the high pozzolanic activity of binary addition, the blended cements (6 and 21%) shows a different behaviour with respect to the control one. The normal consistency water content (up to 10%) and the initial setting decrease in comparison with the control paste. Finally, the compressive strength slightly decreased in the blended cements elaborated with 21% of the pozzolan blend, although the decrease in their strength is lower than the total percentage of cement that is replaced. At 90 days, a recovery of mechanical resistance is observed in the ternary cements as a consequence of the activity developed by the fly ash.
