What is Polycarboxylate Superplasticizer?

Polycarboxylate ether superplasticizer, also known as concrete water reducer, is a new generation of polycarboxylate superplasticizer made of polyoxyethylene ether macromonomer, unsaturated acid, and sulfonic acid group monomer by radical polymerization. Applying Polycarboxylate ether superplasticizer to concrete has high water reduction and low slump loss performance. It can be widely used in pumped concrete, superfluid self-compacting, high-strength, high-performance concrete, and commercial concrete.


Technical principle of superplasticizer admixture

Polycarboxylate ether superplasticizer has a comb-shaped structure, with longer polyoxyethylene chains and high-density sulfonic acid groups in the molecule, which makes it have greater steric hindrance and electrostatic repulsion, providing cement with greater dispersion and higher water reduction.


Features of Superplasticizer Admixtures

(1) Superplasticizer admixture has great dispersibility and an extremely high water reduction rate (water reduction rate can reach more than 35%), guaranteeing high-grade concrete preparation.

(2) Polycarboxylate superplasticizer is an important concrete admixture; Superplasticizer admixture can effectively reduce the viscosity of concrete, have good cohesion, moderate air content, and be suitable for pumping;

(3) Water-reducing admixtures can make concrete with high strength at all ages, good volume stability, outstanding impermeability, freeze-thaw resistance, corrosion resistance, and carbonization resistance;

(4) Superplasticizer admixtures have wide adaptability to Portland cement, ordinary Portland cement, slag silicate, fly ash cement, pozzolan cement, and various admixtures.


Superplasticizer dosage in concrete

The usual dosage is 0.5%-1.0% (calculated by the total amount of cementitious materials), and experiments should determine the optimum dosage according to the engineering materials and characteristics;

The water-reducing agent can be dissolved in water or added to the concrete mixer alone;

It can be combined with a high plasticity polycarboxylate water reducer, lignosulfonate water reducer, and various retarders.

The company provides a complete compounding set and uses technologies to train users. If there are any difficult problems, engineers will come to guide you.


Applications of concrete admixture superplasticizer

Early-strength concrete, retarded concrete, precast concrete, cast-in-place concrete, large-flow concrete, self-compacting concrete, mass concrete, high-performance concrete and fair-faced concrete, ready-mixed and cast-in-place in various industrial and civil buildings concrete. Especially suitable for low-grade commercial concrete.

Concrete admixture superplasticizers can be widely used in large and key national projects such as high-speed railways, nuclear power, water conservancy and hydropower engineering, subways, large bridges, expressways, harbors, and piers.

Concrete admixture superplasticizer is also suitable for various industrial and civil construction and commercial concrete batching plants.

Packaging and Storage of concrete admixture superplasticizer

The liquid of concrete admixture superplasticizer is sealed in 200 kg and 1000 kg barrels.

Anti-leakage, anti-exposure, anti-high temperature during Storage;

The shelf life is one year, and it can only be used after passing the inspection.
