Introduction

In modern construction, the demand for stronger, more durable, and cost-effective concrete solutions has never been higher. ADT ADMIX SNF 2040 is a high-performance superplasticiser formulated from sulphonated naphthalene formaldehyde condensate, engineered to deliver exceptional workability while reducing water requirements in both concrete and mortar. By efficiently dispersing cement particles and increasing their reactive surface area, this admixture enables higher strength with reduced cement content—making it both an economical and performance-driven choice. Ideal for precast applications and projects demanding high early strength, ADT ADMIX SNF 2040 stands as a reliable partner for quality construction.

Key Features of ADT ADMIX SNF 2040

1. Enhanced Workability: Improves concrete flow and ease of placement without increasing water content.
2. Water Reduction: Significantly lowers water requirement while maintaining desired consistency.
3. Strength Optimization: Achieves higher compressive strength with less cement usage.
4. Efficient Cement Dispersion: Separates and exposes more surface area of cement particles for better hydration.
5. Cost-Effective Solution: Reduces overall material costs while maintaining performance.
6. High Early Strength: Perfect for precast concrete and projects requiring rapid strength gain.

Applications of ADT ADMIX SNF 2040

1. Precast Concrete Manufacturing: Ideal for producing precast elements that require high early strength and smooth finishes, enabling faster demoulding and production cycles.
2. High-Strength Concrete: Suitable for projects demanding superior compressive strength while minimizing cement usage.
3. Pumped Concrete: Enhances flowability for easy pumping over long distances or to high elevations without segregation.
4. Dense Reinforcement Areas: Improves workability in congested reinforcement zones where compaction is challenging.
5. Ready-Mix Concrete: Maintains slump and workability during transportation, ensuring consistent quality at the site.
6. Mass Concrete Works: Reduces water content and heat of hydration, beneficial for large pours in dams, foundations, and industrial floors.

Step-by-Step Application of ADT ADMIX SNF 2040

1. Confirm Mix Design & Dosage: Run a trial mix to fix the water–cement ratio and target the slump. Start with the manufacturer’s recommended range (~0.5–2.0% by weight of cement) and refine to meet strength/workability.
2. Batching Sequence: Charge aggregates and ~70–80% of the mixing water, then cement. Add the admixture with the remaining water (pre-diluted if needed). Avoid adding directly onto dry cement to prevent balling.
3. Mixing: Mix until fully uniform and a glossy mortar film appears—no streaks. As a guide: ~60–90 seconds in a central mixer or 70–100 revolutions in a transit mixer after admixture addition.
4. Slump Check & Adjustment: Verify slump/workability. If adjustment is needed, add small, measured increments of admixture (not water), re-mix, and re-test until the target is reached without segregation.
5. Placement & Compaction: Place promptly to leverage the improved flow. Use minimal vibration—just enough to expel air—since the mix is already highly workable; avoid over-vibration that can cause bleed/segregation.
6. Finishing: Begin finishing as soon as the bleed water evaporates. The plasticized concrete will close easily; keep tools clean and avoid adding water to the surface to maintain low w/c and durability.
7. Curing: Start curing early using water curing, wet coverings, or a curing compound. Proper curing locks in the strength gains and reduces shrinkage and surface cracking.
8. Quality Control Tests: Record slump, temperature, unit weight, and (if applicable) air content at site. Cast and label cubes/cylinders for 1-, 7-, and 28-day strengths to confirm performance.
9. Compatibility & Multiple Admixtures: Check compatibility with cement type, SCMs (fly ash/slag), and other admixtures. If using multiple admixtures, dose separately and allow brief mixing between additions.
10. Safety & Storage: Wear gloves, goggles, and follow the SDS. Store the product sealed, in shade, above freezing; use within the labeled shelf life and stir/roll drums before use if settled.
