construction raw material water reduce agent Polycarboxylate
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
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
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.
