Description
Polycarboxylic acid superplasticizers are used as high range superplasticizers in high performance concrete.
Water content:3.6%
(Concrete Superplasticizer PCE Powder)
Overview of Polycarboxylate Superplasticizer PowderPolycarboxylate superplasticizer is a kind of powdery polycarboxylate high performance superplasticizer made by a new process. It has excellent comprehensive index, good dispersibility, high water reduction rate, good adaptability to various cements, and no pollution in green.
Since polycarboxylate superplasticizer is mostly in liquid state, due to the improvement of technology recently, the milling process has been improved, and polycarboxylate superplasticizerpowder has become more common. In contrast, polycarboxylate superplasticizer in powder state provide a lot of convenience from transportation to customer use, and powder polycarboxylate superplasticizer have become the development trend of such products.
Polycarboxylate superplasticizer breaks the routine in production process, adopts thermal synthesis process, does not add isolation agent, and produces products with higher purity. In terms of product performance, high-purity polycarboxylate superplasticizer powder have the characteristics of less dosage, high effective components and good slump retention performance, which further reduces customer costs.

Usage method of Polycarboxylate Superplasticizer Powder
1. According to the concrete design requirements, adjust the water consumption or sand rate through experiments to reach the dosage of water reducer whose slump, strength and setting meet the requirements.
2. Polycarboxylate superplasticizer powder is applicable to high-performance concrete, high-strength concrete and large flow concrete. For concrete higher than C50, raw materials shall be selected according to relevant technical specifications, appropriate mixing process shall be determined, and a certain amount of experimental data shall be obtained. Make the flow performance of the produced concrete meet the construction requirements, and the concrete strength should have a certain surplus coefficient.
3. Polycarboxylate superplasticizer powder can be mixed with mixing water into concrete at the same time, and the effect of mixing water into concrete is better.
Safety and Precautions of Polycarboxylate Superplasticizer Powder
1. Polycarboxylate superplasticizer powder is a weakly alkaline solid, non-toxic, non corrosive and non polluting to the environment. However, it is not edible. When it comes into contact with human body and eyes, it should be washed with clean water as soon as possible. If it causes allergy to some human bodies, it should be treated in time.
2. Polycarboxylate superplasticizer powder should be stored in a cardboard bucket lined with plastic bags to avoid the mixing of rain water and sundries.
3. The shelf life of polycarboxylate superplasticizer powder is 12 months.

FAQ
Q1
What is the main role of PCE powder in concrete?
Answer: The main function of PCE powder in concrete is to increase the fluidity of concrete and reduce water consumption, thereby improving the strength and durability of concrete.
Q2
How to use PCE powder correctly?
Answer: When using PCE powder, it should be added to the concrete in the recommended dosage according to the specific engineering requirements and concrete mix ratio, and should be fully mixed during the mixing process.
Q3
What are the advantages of PCE powder compared with other water reducing agents?
Answer: Compared with other water-reducing agents, PCE powder has a higher water-reducing rate and lower dosage, and at the same time can provide better concrete workability and strength performance.
Q4
What impact does PCE powder have on the environment?
Answer: PCE powder has less impact on the environment because it is a water-soluble polymer compound that will not accumulate in the environment or cause pollution. However, post-use waste still needs to be properly disposed of in accordance with relevant regulations.
Q5
Is PCE powder suitable for all types of concrete?
Answer: While PCE powder works well in many types of concrete, it is not suitable for all types of concrete. In some special cases, such as the use of special aggregates or special requirements for concrete, further testing and evaluation may be required.
