High Range Water-Reducing Admixture UNF*5 Description UNF*5 is a high range water reducer, commonly referred to as a superplasticizer. It is an aqueous solution of a modified naphthalene sulfonate and organic compounds.UNF*5 is made of naphthalene, sulfonic acid, HCHO and Alkali through sulphuration, hydrolyzation, condensation and neutralization reaction. UNF*5 contains no added chloride. UNF*5 meets the requirements of chemical admixture specifications for concrete: GB********7, GB*********3. Uses 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. 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. Compatible with Portland cement, normal Portland cement, Portland slag cement, fly-ash cement and Portland pozzolanic cement etc. Advantages Produce high performance concrete of C*0 with slump of *0mm**0mm or C*0 with slump of **0mm***0mm. Slump control at the job site without adding water. Higher early and ultimate strengths. Given the same amount of cement and slump requirement, this product can increase the concrete stress by *****0%, ****0%, ****0% and ****0% on day 1, 3, 7, and *8 respectively. Improves concrete placebility with no loss in strength. At addition rate of 0.5% *1.0%, UNF*5 can save cement *2%**0% in comparison to the concrete at the same slump and strength. Higher strengths may be achieved more economically. Improves cohesiveness and reduces concrete segregation. Concrete achieves higher durability.
