Polycarboxylate Superplasticizer
HS code: 38244010
Other Name: PCE Powder/Polycarboxylate EtherPCE/High Efficiency Water Reducing Agent/Polycarboxylate superplasticizer ether
Product description:
PCE Polycarboxylate superplasticizer is the newest generation superplasticizer used for concrete in domestic and abroad.This series of products is a new generation of environmentally friendly high performance polycarboxylate superplasticizer,
It is suitable for high volumetric stability, strong durability, high workability of the concrete. It can be widely used in ordinary pumping concrete and high-strength concrete, self-compacting concrete, plain concrete, precast concrete, Self-leveling mortar/Self-Leveling Compound,and other high-performance concrete. It has excellent performance.
Polycarboxylate Superplasticizer is a kind of free-flowing powder form superplasticizer, as a universal product, designed for applications of flowing mortars with universal and special cementitious binders.
Composed of polycarboxylate ether copolymer, its main chain anchors on the surface of cementitious binder particle while the unique comb structure as side chain stretches in the water.
The combination of electrostatic force and steric stretching effect imparts low water demand and high flowing ability to mortars.

Polycarboxylate Superplasticizer is a kind of powder form polycarboxylate ether superplasticizer manufactured through optimizations of molecular configuration and synthesis process.It is suitable for cementitious mortars with requirements of high fluidity and high strength.
Widely used in highways, bridges, dams, tunnels, high-rise buildings and other engineering projects.
With initiating systerm and reaction conditions,we achieve high adaptability.Comparing with PNS and other superplasticizer, PCE has many characteristic advantages in technology and performance as following:
(1) low dosage, high rate of water reducing;
(2) keep concrete good slumption retention;
(3) good compatibility with cement;
(4) small shrinkage of concrete to keep the stability of volume and durability;
(5) environmental in production and usage. Base on above advantages.
Characteristics
As a universal and economical product, pce/Polycarboxylate Superplasticizer is recommended for production of flowing mortars with normal and special cementitious binder system due to the following characteristics,
Super water reducing effect for cement based material applications
Low dosage compared to traditional water reducing agent
High dispersion, fluidity and workability.
Improvement of early and final strength of cement based system
Key properties
- Good dispersability,
- High water reduction
- Excellent adaptability with kinds of cement
- High flowability in mortar or concrete
Development of concrete water reducing admixture:
the first generation water reducers are:lignosulfonate types(Na,Mg,Ca).
the second generation water reducers are:naphthalene sulfonate type,Sulfonated melamine formaldehyde type,aliphatic series,aminosulfonic acid series.
the third generation water reducer are :Polycarboxylate based superplasticizer.
Advantage
1. Better adaptability with cement.it is compatible with most of retarding materials.
2. It is suitable for long distance transit and store. With stable quality and simple compound, it has the outstanding benefit.
3. It has good performance in slump retention special for the pumping flow plasticize concrete.
4.It is used in high performance concrete of high-strength,high elasticity modulus,high anti-permeability,low shrinkage,low creep and well durability.
