EUNICEM SDMW is a liquid permeability reducing admixture for use in all types of mortar and concrete mixes. EUNICEM SDMW has particular applications in the cast stone and block making industries, where high aggregate/cement ratios are normally used.
EUNICEM SDMW is supplied ready for use. It should be added to concrete mixes during the mixing process at the same time as the water or the aggregates. It should not be added directly to the cement. No extension of normal mixing time is necessary.
• EUNICEM SDMW can be added by means of an automatic dispenser.
• It can be used with grey or white Portland cement or with pigmented mixes to help prevent unsightly elorescence and irregular leaching out of pigments.
• Precast units, blocks, bricks and other semi-dry concretes containing this type of permeability reducer, retain their original clean appearance when exposed to the elements for considerable periods.
• The durability of concrete finishes is increase because the penetration of rain and moisture is greatly reduced, giving improved resistance to frost damage.
• Aggregate mottling can be prevented in most mixes.
• The reduction in permeability obtained with EUNICEM SDMW is long lasting.
