TECHNICAL SPECIFICATIONS

For the technical enthusiasts, here’s a detailed look at Sika® ViscoCrete®-3000-10:

Property	Specification
Concrete placing	State-of-the-art techniques for mixing, placing, vibrating, and curing must be followed.
Curing	Effective curing measures should be taken, and using Sika curing compounds is recommended. Suitable for steam curing.
Specific Advice	Add Sika® ViscoCrete®-3000-10 to the gauging water before adding it to the dry mix or separately to the wet concrete mix. Maintain a minimum wet mixing time of 60 seconds. Balance batching water should be added after at least 2/3 of wet mixing time to avoid excess water in the concrete.

APPLICATION INFORMATION

• Recommended Dosage: Use 0.7 to 2.5 liters of Sika® ViscoCrete®-3000-10 per 100 kg of cement.
• Compatibility: It can be combined with various Sika products, such as Sikament®, Sika® Aer, Sika® Pump, and Sikacrete® PP-1. However, it must be added separately to the mix, not pre-mixed. It is compatible with all types of Portland cement.

IMPORTANT CONSIDERATIONS

To fully harness the potential of Sika® ViscoCrete®-3000-10 in your concrete project, follow these detailed construction instructions for optimum results:

1. Concrete Mixing:

• Begin with high-quality materials, including cement, aggregates, and water.
• Add Sika® ViscoCrete®-3000-10 to the gauging water before introducing it to the dry mix. Ensure uniform dispersion.

2. Mixing Time:

• To optimize the ultra-high-range water reducer’s performance, maintain a minimum wet mixing time of 60 seconds.

3. Adding Water:

• When adding the remaining batching water to adjust the concrete consistency, do so after at least 2/3 of the wet mixing time. This prevents excess water in the concrete, ensuring the desired properties are maintained.

4. Concrete Placement:

• Use state-of-the-art concrete technology for mixing, placing, vibrating, and curing. Ensure you follow industry best practices for concrete placement.

5. Curing:

• Effective curing measures are crucial to maximize the strength and durability of your concrete. Consider using Sika curing compounds. Sika® ViscoCrete®-3000-10 is suitable for concrete that requires steam curing.

6. Equipment:

• Use appropriate concrete mixing equipment to ensure proper dispersion of the admixture. Hand mixing should be avoided for consistency and quality control.

7. Dosage Control:

• Carefully control the dosage of Sika® ViscoCrete®-3000-10, adhering to the recommended range of 0.7 to 2.5 liters per 100 kg of cement. Overdosing can impact workability and setting time, so precise measurement is critical.

8. Trial Mixes:

• It’s advisable to perform trial mixes to establish the exact dosage rates required for your specific project. This helps tailor the admixture to your unique requirements and ensures consistent results.

9. Technical Assistance:

• If you encounter challenges or have specific questions about the application of Sika® ViscoCrete®-3000-10, don’t hesitate to reach out to Sika’s Technical Department for expert guidance and support.
