Product Description

Named as SNF ,FDN, concrete admixture ,water reducer ,chemical construction materials ……

SNF is a modified β-naphthyl sulfonate formaldehyde condensation . SNF is formulated to comply with pecifications for Chemical Admixtures for Concrete,a superior dispersing admixture having a marked capacity to disperse the cement agglomerates normally found in a cement water suspension.

Suit for ASTM C494 as a Type A and Type F admixture

Product Advantages

• 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 high efficient cement to achieve early strengths

• At high slump, exhibits no significant segregation in comparison to concrete without superplasticizer at the same slump

Uses

SNF produces concrete with extremely workable characteristics referred to as high slump. SNF also allows concrete to be produced with very low water/cement ratios at low or normal slumps. SNF 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. SNF will also fluidize concrete, making it ideal for tremie concreting or other applications where high slumps are desired.

Addition Rates

Addition rates of SNF can vary with type of application, but will normally range(0.5%-1.0%)of cement.In most instances the addition(0.6%-0.7%)of cement will be sufficient.
