concrete water reducing 40% 50% pce polycarboxylate superplasticizer
Polycarboxylate Superplasticizer Water reducing style (Elt-WR)is a environmental polycarboxylate superplasticizer. It 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.
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.

Application
A..Elt-WR 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
Features & Benefits
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.
Sheet for Elt-WR is showed as follows. It was obtained according to the China National Standard Method:
Use Method:
A. The dosage of Elt-WR is suggested as follows (wt.% of cement): 0.25%-0.8%.
B. It can be mixed in metric water or added in concrete mixer. The recommended stirring time is 150s at least. Concrete mixing test should be made before using in order to insure concrete quality.
C. It can be compounded together retarder, defoamer, air-entertraning reagent, lignin sulfonic natrium and so on.
D. product is a product as raw materials. It is not suggested to use Elt-WR products directly in concrete or other materials without formulation blending. The compatiblity of Elt-WR products to particular cement, aggregate and the other raw materials in the application is not guaranteed. It should be obtained through trial mixes and formulation technologies by the users.
Packaging and Storage
A. Standard Packing: 230kg/200L PE drum ,1100kg/IBC tank
B. Sealed stored under 0-35ºC,far away from sunlight.
C. Shelflife is normally 12 month. It is tested eligibility and then used when it exceeds.
D. Delivery time: 3-15days
