high reducing rate Liquid 40% 50% polycarboxylate water reducer as
construction raw material
1.polycarboxylate water reducer Introduction
polycarboxylate superplasticizer is latest generation concrete
admixture, compare with other concrete admixture,its advantage as
a,higher water reducing ratio.
c,higher concrete strength.
For liquid type polycarboxylate superplasticizer,it is very
convenient for use,can be added directly to concrete;can also be
diluted to lower solid content with water.
2.polycarboxylate water reducer Characteristic
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.polycarboxylate water reducer 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.polycarboxylate water reducer Application area:
high speed railways; highways; airports; ports; (hydro) power
plants in forms of pre-cast concrete, reinforced concrete and
pre-stressed concrete; specifically designed for projects which
have more demanding requirements on transportation / construction
period as well as slump retention (e.g nuclear plants)
6.polycarboxylate water reducer 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.
7.polycarboxylate water reducer 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.
