When faced with aggregate variances, changes in cement characteristics, or dealing with difficult to fill mold configurations – a common response is to run mixes drier than normal.

While this is helpful in maintaining normal production rates it can pose consequences downstream such as chipping, breakage, poor splits, and efflorescence issues. That is because dry-cast concrete performance hinges on the paste to aggregate interface.

Our Tech Shield 900 Series of Advanced ECAs (efflorescence control agents) address such challenges by reducing stickiness and increasing mix moisture tolerance. This improves concrete flow, compaction, and paste-aggregate coverage/bonding.
