Product Description
Sodium Naphthalene Sulfonate Formaldehyde Condensate is an aqueous solution of a modified naphthalene sulfonate. NSF is a superior dispersing admixture having a marked capacity to disperse the cement agglomerates normally found in a water-cement suspension. The capability of NSF, in this respect, exceeds that of normal water-reducing admixtures. It is a low viscosity liquid manufactured for use as received. NSF contains no added chloride. NSF is formulated to comply with Specifications for Chemical Admixtures for Concrete, ASTM C494 as a Type A and Type F admixture, and ASTM C1017 as a Type I admixture.
Uses
NSF produces concrete with extremely workable characteristics referred to as high slump. NSF also allows concrete to be produced with very low water/cement ratios at low or normal slumps. NSF is ideal for use in pre-stress, precast, ready-mixed,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. NSF will also fluidize concrete, making it ideal for tremie concreting or other applications where high slumps are desired.
Product Advantage
Can produce high slump flowable concrete with no loss in strength
Can produce low water/cement ratio concrete and therefore, high strengths
Concrete produced with Type I cement may be substituted for normal concrete produced with Type III cement to achieve early strengths
At high slump, exhibits no significant segregation in comparison to concrete without a super plasticizer at the same slump
Compatible with Portland cement, normal Portland cement, Portland slag cement, fly-ash cement and Portland pozzolanic cement, etc.
High-range water-reducing admixture
