Overview of 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.

What is the working principle of polycarboxylic acid superplasticizer?

Answer: Polycarboxylic acid superplasticizer mainly absorbs on the surface of cement particles, generates electrostatic repulsion, and disperses cement particles, thereby reducing mixing water consumption and improving the fluidity and workability of concrete. At the same time, polycarboxylate superplasticizer can inhibit the slump loss of concrete and maintain good working performance for a long time.


What are the characteristics of polycarboxylic acid superplasticizer?

Answer: Polycarboxylate high-efficiency water-reducing agent has the characteristics of high water-reducing rate, low dosage, environmental protection and non-toxicity. Compared with traditional naphthalene-based water-reducing agents, polycarboxylate water-reducing agents have better adaptability to cement and can effectively solve the problem of incompatibility between naphthalene-based water-reducing agents and cement. In addition, polycarboxylate superplasticizer also has the advantages of good slump retention, high concrete compressive strength, and low dosage.


How to choose a suitable polycarboxylate superplasticizer?

Answer: Choosing a suitable polycarboxylate superplasticizer requires consideration of factors such as engineering requirements, raw material properties, and construction environment. The polycarboxylate water-reducing agent with appropriate water reduction rate and dosage should be selected according to the needs of the specific project, and attention should be paid to its compatibility with raw materials such as cement, sand and gravel. At the same time, you should choose a brand of polycarboxylate superplasticizer with stable quality, environmental protection and non-toxicity.


What issues should we pay attention to when using polycarboxylic acid superplasticizer?

Answer: When using polycarboxylate high-efficiency water-reducing agent, attention should be paid to controlling the amount of water-reducing agent and water consumption to avoid affecting the performance of concrete due to too much or too little water consumption. At the same time, avoid mixing with other admixtures to avoid adverse reactions. In addition, various performance indicators of concrete should be tested regularly to ensure that the concrete quality meets the project requirements.


What impact does polycarboxylic acid superplasticizer have on the performance of concrete?

Answer: Polycarboxylate superplasticizer has many effects on the performance of concrete. First, by reducing water consumption, the strength indicators such as compression and flexural resistance of concrete are improved. Secondly, improve the fluidity and workability of concrete, making it easier to pour and compact. In addition, the slump loss of concrete is suppressed, allowing it to maintain better working performance over a long period of time. At the same time, polycarboxylate superplasticizer can also improve the impermeability and durability of concrete.


How is the adaptability of polycarboxylate superplasticizer to cement?

Answer: There are certain differences in the adaptability between polycarboxylate superplasticizer and cement. The main reason is that different cements have different compositions and chemical structures. Therefore, when selecting a polycarboxylate superplasticizer, its compatibility with the cement used should be considered. In order to improve the adaptability of polycarboxylate superplasticizer and cement, some measures can be taken, such as adjusting the mix ratio and adding retarder.


How to solve the problems in the use of polycarboxylic acid superplasticizer?

Answer: When using concrete foaming agent, the slurry should be prepared accordingTo solve the problems in the use of polycarboxylic acid superplasticizer, corresponding measures need to be taken according to the specific situation. For example, if the amount of concrete bleeding is too large, the sand rate can be appropriately increased or the mix ratio can be adjusted; if the concrete hardening time is too long, the amount of water-reducing agent can be appropriately reduced or the amount of cement can be adjusted.
