RHEOMAC® UW 450
Rheomac UW 450 anti-washout admixture is a patented, ready-to-use, liquid cellulose-based admixture that is specially developed for underwater concrete applications. Concrete containing Rheomac UW 450 admixture exhibits superior resistance to washout of cement and fines, while impeding the blending of external water into the plastic concrete.
Features
Reduction in washout of cement and fines
Reduction in segregation, even with highly fluid, high water-cementitious material ratio concrete mixtures
Thixothropic action that provides concrete stiffening after placement
Slump retention characteristics similar to plain concrete Minimal effect on setting characteristics
Reduction or elimination of concrete bleeding
Batch plant or job site addition
Benefits
Superior and predictable in-place concrete properties
Dewatering costs reduced/eliminated
Environmental impact of cement washout in water minimized
Flexibility in batching procedures
