PC ZY-J 日期：2017-6-12 11:06:52 点击数：747 Description PC ZY-J is a super high-performance water soluble concrete additive for the production of high strength concrete. Based on Polycarboxylate Acid. Chloride-free.Delivered in liquid 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. Hydraplast Super 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 0.3-0.5 L. of PC ZY-J 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.  *Should not be added directly to dry cement.  *For advice and assistance on how to conduct such tests, the Technical Services of SDZY are available. Packages and Storage  *Packing in 1000KGS per IBC drum with pallet. Or Flexitank in 20’feet container loading 20tons/20’fcl  *Unlimited in well sealed and unbroken drum, stored in shade and avoiding excessive heat.
