Uses:

1. UNF-5 produces concrete with extremely workable characteristics referred to as high slump. UNF-5 also allows concrete to be produced with very low water/cement ratios at low or normal slumps.

2. UNF-5 is ideal for use in prestress, precast, bridge deck or any concrete where it is desired to keep the water/cement ratio to a minimum and still achieve the degree of workability necessary to provide easy placement and consolidation. UNF-5 will also fluidize concrete, making it ideal for tremie concreting or other applications where high slumps are desired.

3. Compatible with Portland cement, normal Portland cement, Portland slag cement, fly-ash cement and Portland pozzolanic cement etc.
