PNS ZY-C 日期：2017-6-12 11:04:12 点击数：457 Description PNS ZY-C is a high-performance water soluble concrete additive for the production of high strength concrete. Based on Sodium Salt of High Molecular Weight Naphthalene Sulphonic Formaldehyde Condensate. Stable sulphate content.Nearly Chloride-free.Delivered in Powder form. Object  *Mass-pours of concrete  *Slabs and foundations  *Airports,Dams, Road, High-way, bridge, column constructions  *Pre-stressed concrete surfaces  *Pre-cast factories for the construction of concrete elements where fast      *re-cycling of forms is of importance Advantage  *Improves compressive, flexural and bonding strength  *High early strength when used also as an accelerator  *Improves durability of concrete  *Improves flow-characteristics of concrete and thus also pumpability  *Improves wear and abrasion resistance of finished surface  *Increases density of concrete and thereby increases water-proofing characteristics of concrete Standard Meets  *GB8076-2008 ;  *A.S.T.M. C494-1980 Type A&F;  *BS 5075 Part 3:1984. Instructions for Use  *For ensuring high early strength (pre-cast factories, pre-stressed structures, road and bridge-repairs). Keep water content lower in accordance with enclosed diagram.  *For improving flow-characteristics a greater proportion of water must be added. PNS ZY-C must be mixed with water prior to mixing into concrete. Water addition rates depend on desired effect. Generally, for a certain effect to be obtained, as water content in relation to solid content is increased, a greater quantity of the mix must be dispensed.  *Dosage is 0.6-1.0 kgsbof PNS ZY-C in relation to cement 100 kgs., depending on the workability and strength property that are required. The optimum dosage for a certain required effect is best determined by a test at site.  *For advice and assistance on how to conduct such tests, the Technical Services of SDZY are available. Packages and Storage  *Packing in 25kg/40kg/650kgs bags,or under clients’ requestion.  *Unlimited in well sealed and unbroken bags, stored in shade and avoiding excessive heat.
