This product is used for formulating コンクリート混和剤. Its main functions in concrete include:
- Improved Fluidity: Enhances concrete’s workability for easier placement and compaction.
- Water Reduction: Reduces mixing water significantly while maintaining similar slump levels.
- Strength Enhancement: Boosts mechanical properties like compressive strength.
- Durability Improvement: Reduces internal porosity to extend concrete lifespan.
Dosage Guidelines
- General admixture dosage: ≤5% of cement weight.
- Naphthalene-based powder dosage: 0.75-1.5% of cement weight.
Calculations
- For 1 ton (1000kg) of cement:
- Minimum: 1000kg × 0.75% = 7.5kg
- Maximum: 1000kg × 1.5% = 15kg
Concrete Mix Application
The dosage per cubic meter of concrete depends on specific mix designs and project requirements. Always calculate based on actual cement content in the mix.
How to Use
Dosage Range:
0.75–1.5% by cement weight (adjust based on mix design and desired slump).
Example: For 1,000 kg cement, use 7.5–15 kg powder.
Mixing Guidelines:
Add to dry mix or dissolve in mixing water for uniform dispersion.
Test batches recommended to fine-tune dosage.
Compatibility:
Works with Portland cement, fly ash, and slag.
Pair with air-entraining agents for freeze-thaw resistance.
Key Advantages
Sustainability: Reduces cement and water use, lowering CO₂ emissions.
Versatility: Suitable for normal to high-strength concrete.
Reliability: Consistent performance across temperature ranges (5–35°C).
Safety & ストレージ
Store in dry, cool conditions to prevent caking.
Wear gloves and goggles during handling.
Avoid contact with eyes and prolonged skin exposure.
結論
Naphthalene-based high-efficiency water reducers are indispensable for modern construction, delivering superior performance, cost savings, and sustainability. By optimizing concrete properties, they enable safer, longer-lasting structures while meeting global environmental goals.
