1.Introduction
 polycarboxylate superplasticizer is a concentrated product. Due to high water reducing rate and low alkali content, it can be widely used in all kinds of high-performance concrete such as retarding concrete,precast concrete,cast -in-place concrete,high performance concrete,flow state concrete,self-compacting concrete and mass concrete. It is widely used in project such as high-speed railway,large bridge,hydroelectric project,nuclear power plant,metro,high way,harbor.
2.Principle of function
Molecular main chain of polycarboxylate high performance water reducer is firmly adsorbed on surface of cement granule where can efficiently counteract hydration reaction and increase its plasticity.Branched chain surround cement granule having sterically hindered and electrostatic exclusion function which is different from conventional imparts excellent dispersing ability and effect of water reducing which make integrative characteristics of concrete improve greatly.3.Technical specification

4.Production Characteristic
A.  High water reduction: The water reduction rate of concrete is above 40%.
B.  Easying to control production: Controling water reduction ratio, plasticity and air entraining by adjusting molecular weight of main chain, length and density of side chain, type of side chain group.
C.  Good dispersion: High fluidity of concrete results in deposing and compacting easily for self-compacting concrete.
D.  High strength gained rate: Greatly increasing early and after strength, reducing energy loss.  Reduction of cracking, shrinkage and creep.
E.  Wide adaptability: It is compatible with ordinary silicate cement, silicate cement, slag silicate cement and all kinds of blendings having excellent dispersibility and plasticity.
F.  Good strength and durability: low lacuna rate, low alkali and chlorin-ion content. Enhancing concrete strength and durability.
G.  Environmental friendly products: No pollution during production.
H.  Low-consume, Low-cost: It can be produced in little cycle and little-consume. So it having low-cost. Especially it can be used in commercial concrete.
5.Scope of application
A..it is a superplasticizer used in premix of construction and cast-in-place concrete.
B. It is especially suitable high strength concrete for railway, haven, traffic, bridge and electric power and so on.
C.It is suitable for the preparation of high strength, high durability, self-compacting, steel fiber and self-leveling concrete
6.Package & Storage
1. Liquid product: 220KG PE drum ,1100kg/IBC tank,.
