Description:

MasterMatrix UW 440 anti-washout admixture is a ready to use, powdered admixture specially developed for concrete placed underwater. Concrete treated with MasterMatrix UW 440 exhibits superior resistance to washout of cement and fines.

MasterMatrix UW 440 can also be used, at a lower dosage rate, in piling applications to prevent poor surrounding ground conditions from absorbing moisture from the concrete mix, and therefore making post pouring operations such as placing the reinforcing cage easier.

Features & Benefits :

• Minimal to no effect on water demand.
• Reduces or eliminates concrete bleeding.
• Workability characteristics equal to untreated concrete.
• Virtually eliminates segregation even with highly fluid, high water-cementitious ratio mixes.
• Reduces/eliminates costly methods of de-watering.
