Abstract:
The utilization of waste waters from zeolite production, for the activation of mixtures containing high content of granulated blast-furnace slag with moderate amounts of portland cement clinker and gypsum, was examined. The evaluation of properties of the product, depending on the composition of the starting blend, showed that good compressive strength and satisfactory resistance to carbonation, sulfate attack and freezing and thawing cycling can be obtained with some compositions.
