Does MetaMax® increase the water demand?
Because MetaMax has a finer particle size than cement, the water demand of the MetaMax is slightly more than cement. In addition, by including MetaMax, the mixture becomes more cohesive, which aids in pumpability and trowelability, but may also make the mixture look as if a large amount of water must be added. The best way to offset the additional water demand is to increase the amount of water-reducer. If no additives except for MetaMax are being used, then the minimal amount of water should be added to maintain workability. Workability should be evaluated by troweling some of the mixture, not by watching how the mixture performs in the mixing equipment.
