The features of the polycarboxylate superplasticizer

  1. Anionic / Non-ionic Liquid Admixture: The polycarboxylate superplasticizer is available in both anionic and non-ionic forms, offering versatility in application. It is a liquid admixture that can be easily mixed with concrete.
  2. Low Chloride, Low Alkali, Non-toxic: This type of polycarboxylate superplasticizer has low chloride and alkali content, making it suitable for use in reinforced concrete structures where the presence of chlorides or alkalis can lead to corrosion. It is also non-toxic, ensuring a safe working environment.
  3. Excellent Water-Reducing Ability: The polycarboxylate superplasticizer exhibits outstanding water-reducing capabilities. It can significantly reduce the amount of mixing water required in concrete, allowing for higher strength and improved workability.
  4. High Strength Enhancing Ability: When used in conjunction with mineral admixtures such as fly ash or slag, the polycarboxylate superplasticizer enhances the strength of concrete structures. This combination results in improved performance and durability.
  5. No Bleeding, Anti-Segregation, Easy to Pump and Transport: The polycarboxylate superplasticizer ensures that concrete does not segregate or bleed, resulting in a homogenous mixture. It also improves the pumpability and transportability of concrete, facilitating construction processes.
  6. Good Appearance of Hardened Concrete: Concrete mixed with polycarboxylate superplasticizer exhibits a pleasing appearance with an absence of water lines, large bubbles, or color differences. This contributes to the aesthetic appeal of the finished structure.
  7. High Durability: The use of polycarboxylate superplasticizer significantly improves the durability of concrete. It enhances compactness, freeze-thaw resistance, carbonation resistance, elastic modulus, and impermeability. It also reduces drying shrinkage and creep, resulting in long-lasting and resilient structures.
  8. Stable Performance, Non-Precipitation: The polycarboxylate superplasticizer offers stable performance throughout the mixing and curing process of concrete. It does not precipitate or separate, ensuring consistent and reliable results.

Overall, these features make polycarboxylate superplasticizers a preferred choice for achieving high-quality, durable, and workable concrete in various construction applications.

Application of Concrete water reducer

Concrete water reducers, such as polycarboxylate superplasticizers, are widely used in the construction industry to improve the quality and performance of concrete. Here are some key applications of concrete water reducers:

  1. Improved Workability: Water reducers enhance the workability of concrete by reducing the amount of water needed for a given slump or flow. This allows for easier handling, placement, and finishing of concrete, especially in situations where increased fluidity is required.
  2. Increased Strength: Concrete water reducers can significantly enhance the strength of concrete. By reducing the water-cement ratio and increasing the density and compaction of the concrete mixture, water reducers help improve the compressive, tensile, and flexural strengths of the hardened concrete.
  3. Higher Durability: The use of water reducers in concrete can greatly improve its durability and resistance to various environmental factors. This includes enhancing freeze-thaw resistance, reducing shrinkage and cracking, improving resistance to chemical attack, and increasing the overall durability and lifespan of concrete structures.
  4. Reduced Permeability: Water reducers contribute to denser and more compact concrete, leading to decreased permeability. This improves the resistance of concrete to water penetration, moisture ingress, and the detrimental effects of aggressive substances, such as chlorides and sulfates.
  5.  Enhanced Pumpability: Concrete water reducers improve the flow and pumpability of concrete mixtures, making them easier to transport and place in large-scale construction projects. This is particularly beneficial for projects with complex or congested reinforcement, where good workability and flowability are crucial.
  6. Improved Aesthetics: Water reducers help to produce concrete with a smooth and uniform surface finish, reducing the occurrence of surface defects such as bug holes, honeycombing, or segregation. This results in visually appealing and aesthetically pleasing concrete structures.

Overall, concrete water reducers play a vital role in enhancing the workability, strength, durability, and aesthetics of concrete, making them essential additives in modern construction practices.

The technical specifications for TPEG

TPEG, also known as TPEG ether or TPEG polymer, is a key ingredient used in the manufacturing process of high-performance polycarboxylate water reducers. Here are the technical specifications for TPEG:

  1. Appearance: TPEG is a white flake material.

  2. Hydroxyl Value: The hydroxyl value of TPEG is measured in terms of milligrams of potassium hydroxide (KOH) per gram of TPEG. The specified range for TPEG’s hydroxyl value is between 20 and 25 MgKOH g.

  3. pH Value: TPEG’s pH value, measured in a 1% water solution, falls within the range of 5 to 7. This indicates that TPEG is slightly acidic or neutral in nature.

  4. Degree of Unsaturation: The degree of unsaturation of TPEG is a measure of the presence of double bonds in its molecular structure. TPEG must have a minimum degree of unsaturation of 0.39 mol/kg.

  5. Double Bond Retention: The double bond retention of TPEG, expressed as a percentage, refers to the preservation of double bonds during the manufacturing process. TPEG must have a minimum double bond retention of 90%.

These technical specifications are important quality indicators for TPEG, ensuring that it meets the required standards for the production of high-performance polycarboxylate water reducers.

Packing and shipping of Concrete water reducer

  1. Packaging: The concrete water reducer is typically packaged in 25kg lining plastic bags. This packaging ensures the proper containment and protection of the product during transportation and storage.
  2. Storage: The concrete water reducer is classified as nonhazardous. It should be stored in a cool and ventilated place to maintain its quality and effectiveness. This helps prevent exposure to excessive heat, direct sunlight, and moisture, which can potentially degrade the product.
  3.  Delivery: The delivery time for the concrete water reducer is within 15 working days. This timeframe specifies the estimated duration from the order placement to the completion of the product delivery.
  4. Shipment:FOB,CFR,CIF, By sea
