Usage:

  • Ready-Mix Concrete: Ideal for use in ready-mix concrete plants to enhance workability, improve strength, and reduce water content.
  • Precast ConcrSikament NNPc ete: Enhances the performance of precast elements, improving handling, surface finish, and compressive strength.
  • High-Performance Concrete: Used for demanding applications, such as high-rise buildings, bridges, and infrastructure projects, where strength and durability are critical.
  • Durability Enhancements: Provides concrete with improved resistance to shrinkage, cracking, and environmental exposure, increasing its longevity.
  • Flowability Improvement: Suitable for applications requiring high-flow concrete, complex formwork, or intricate designs.

Coverage:

Sikament® NNPc is a high-performance, non-priming, and water-reducing superplasticizer designed to improve the workability and strength of concrete. The coverage rate depends on the dosage used and the specific conditions of the application. Typically, the dosage ranges from 0.2% to 1% by weight of cement depending on the desired level of workability, strength, and water reduction. This translates to approximately 0.8 to 3 liters per 100 kg of cement.

Application:

Sikament® NNPc is suitable for a wide range of concrete applications, including:

  1. Ready-Mix Concrete: It is commonly used in ready-mix plants to improve the quality and workability of the concrete, allowing for easier handling, placement, and finishing.
  2. Precast Concrete: Perfect for precast concrete products where high strength and enhanced durability are crucial.
  3. High-Strength Concrete: Especially useful in high-strength concrete applications where reduced water content and improved bonding are needed.
  4. Industrial Floors: Enhances the workability and durability of industrial flooring, making it more resistant to heavy loads and wear.
  5. Paving & Decorative Concrete: Used to enhance the texture and appearance of concrete in decorative paving and other aesthetic applications.
  6. Screeds and Mortars: Ideal for use in floor screeds and mortars, improving the flow and performance of the mix.
  7. Concrete Repair: Can be used in concrete repairs to ensure better bonding and strength.

Application Process:

  1. Mixing: Add Sikament® NNPc directly to the batching process. Typically, it is added to the mix at the same time as the water or after the cement has been added. Follow the manufacturer’s recommendations for the correct dosage (usually 0.2% to 1% by weight of cement).
  2. Workability: Sikament® NNPc improves the flowability of concrete, making it easier to mix, pour, and compact. This is especially useful for dense and stiff mixes.
  3. Curing: Proper curing is essential for maximum strength development. Allow the concrete to cure for 24 to 48 hours under optimal conditions to achieve full strength and durability.
  4. Testing: Ensure that the concrete mix meets the required strength and workability before use. Adjust the dosage if necessary.

Coverage Advantage:

Sikament® NNPc offers excellent efficiency at low dosage rates, allowing for significant improvements in concrete performance without the need for additional water. Its ability to reduce water content while maintaining workability results in high-strength, durable concrete with enhanced resistance to cracking and shrinkage. This can help reduce the need for excess water and improve the concrete’s long-term durability and sustainability
