construction raw material water reduce agent Polycarboxylate superplasticizer PCE
polycarboxylate superplasticizer (PCE) is a new type of water-reducing agent. The utilization of this product can improve the slump retention performance of the concrete, ensuring a barely no loss within half an hour and a small loss within 1 hour. This product also plays a good role in reducing cement additive amount, improving water reducing efficiency and dropping shrinkage rate. Using this product can validly boost concrete flowability so to extend the setting time during construction. What's more, it can promote the workability and physical properties of the concrete, which is important for construction quality.

A. Good slump retention ability: Delaying time of transporting concrete and time of detention at construction site, guarantee concrete pumpability.
B. Slow release: It is low initial water reduction and high later, it has excellent dispersion for cement. It can keep concrete good slump retention during 1-3 hours.
C. Special adaptability: It can be widely used in premix of common concrete, gushing concrete, high strength and durability concrete.
D. High strength gained rate: Greatly increasing early and after strength, reducing energy loss.
E. It can be used by mixing WR PCE together to reach the requirements of client.
4.PCE 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.
5.PCE Scope of application
A. Elt-SR is a superplasticizer used in premix of construction and cast-in-place concrete, especially in area with hot weather.
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.PCE Methods Of Use
A. The dosage of Elt-SR 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, sodium gluconate and so on.
D.Elt-SR is sold as raw materials. It is not suggested to use this products directly in concrete or other materials without formulation blending. The compatibility of this product 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.
7.PCE Package & Storage
A. Liquid product: 230kg/200L PE drum ,1100kg/IBC tank,.
B.Sealed stored under 0-35℃,far away from sunlight.
C. Shelflife is normally 12 month. It is tested eligibility and then used when it exceeds.
8.PCE Handling Notes
A.Elt-SR is free from alkaline. It is no toxic, hazardous, and corrosive. It is inedible.
B. When it contacts to eyes and skin, the affected area shall be immediately rinsed with plenty of water for minutes. Consult a physician if irritation persists.
C. Keep container closed when it is not in use. Do not store the product directly under sunlight.
