Uses of PCE Based Admixture

  • PCE Based Admixture is the ideal choice to achieve a high-quality concrete mix with accelerated strength development, extended workability, and improved durability.
  • By incorporating polycarboxylate superplasticizer ether into the concrete mix, you can achieve accelerated hydration of cement particles. This results in early strength development, allowing for faster construction cycles and reduced waiting times.
  • The exceptional placing characteristics provided by polycarboxylate superplasticizer ether ensure that the concrete is highly workable and easy to handle. This allows for efficient placement, even in complex or congested formwork, ultimately improving productivity and construction timelines.
  • Moreover, the use of polycarboxylate superplasticizer ether enhances the durability of the concrete. It increases ultimate strengths, providing a higher level of structural integrity and resistance to cracking. Additionally, the reduced permeability of the concrete helps to minimize the ingress of harmful substances, such as moisture or chloride ions, thus extending the service life of the structure.

Typical Applications & Advantages of PCE Based Admixture

PCE Based Admixture is a versatile solution for achieving high-quality and durable concrete. It offers several benefits that contribute to the production of superior concrete structures:

  1. Powerful plasticizing action: Polycarboxylate concrete admixture provides a significant increase in initial workability, making the concrete mix easier to handle and place. This plasticizing action improves the flowability of the mix, allowing for efficient and hassle-free construction.
  2.  Reduced water/cement ratio: By utilizing polycarboxylate concrete admixture, it is possible to decrease the water-to-cement ratio to the maximum permissible limit. This reduction in water content maintains workability while optimizing cement hydration, leading to the production of high-strength concrete.
  3. High-performance concrete: Polycarboxylate concrete admixture has the capability to deliver high-performance concrete consistently, regardless of the job site or project requirements. This enables contractors and builders to meet the demanding specifications of various construction projects.
  4. Compatibility and versatility: Polycarboxylate concrete admixture can be used alone or combined with other additives to create specialized concrete mixes. Whether it is pumping concrete, ready-mixed concrete, or other specific applications, the admixture can be tailored to meet the unique requirements of each project.

Instructions for Use

To ensure the effective use of Polycarboxylate Superplasticizer, please follow these instructions:

  1. Mixing water addition: The preferred method is to add the superplasticizer to the mixing water. This allows for proper dispersion and uniform distribution of the admixture throughout the concrete mix.
  2.  Ready mixed concrete: If you are using ready mixed concrete, the superplasticizer can be added directly to the fresh concrete. This is typically done in the mixing truck. Consult with your supplier to determine the appropriate dosage and mixing procedures.
  3. Mixing time: It is crucial to mix the concrete at a high speed for approximately 6 to 8 minutes. This ensures thorough blending of the superplasticizer with the other components of the concrete mix and enhances its dispersing effectiveness.
  1. The optimum dosage of Polycarboxylate Superplasticizer for your specific requirements should be determined through trials using the actual materials and conditions that will be encountered during use. It is important to conduct these trials to achieve the desired concrete properties and performance.
  2. While there is a normal dosage range, it is possible to adjust the dosage outside of this range to meet specific mix requirements. In such cases, it is recommended to contact DongKe for expert advice and guidance on the appropriate dosage adjustment.
  3. Polycarboxylate Ether Superplasticizer provides excellent control over both initial and final setting times of concrete. The specific setting times can vary depending on factors such as cement type, mix design, and ambient temperature. It is important to consider these factors when using the superplasticizer and adjust the dosage accordingly.
  4. When using Polycarboxylate Superplasticizer, it should not be combined with any other admixture unless prior approval is obtained from DongKe. It is essential to ensure compatibility between different admixtures to avoid any negative effects on the concrete mix.
  5. For further guidance on dosage, setting times, or compatibility, we recommend reaching out to DongKe for personalized advice based on your specific project requirements.
