Product Description

roduct Description High Range Water-Reducing Admixture Sodium Naphthalene Formaldehyde, Poly Naphthalene Sulfonate Formaldehyde Condensate, Concrete Admixture Uses Sodium Naphthalene Formaldehyde produces concrete with extremely workable characteristics referred to as high slump. PNS also allows concrete to be produced with very low water/cement ratios at low or normal slumps. Sodium Naphthalene Formaldehyde 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 Sodium Naphthalene Formaldehyde Specification: Solid Content *2% min Moisture 8.0 % max Fineness 5.0% max PH value 7 - 9 Chlorides Content 2.0% max Surface Tension ****2 Mn/m Cement Flowing Rate **0mm min Concrete Reducing Water Rate *8% min Sodium Sulfate Content *8% max (5%max is also available)
