Anti-foaming Agents Concrete Defoamers for Construction
-------XRT-DA
The XRT-DA Defoamer is a proprietary high-carbon alcohol polyether ester solution engineered specifically for the cement concrete admixture industry, particularly for use with polycarboxylate superplasticizers. It selectively eliminates harmful, unevenly sized bubbles while preserving beneficial air-entrained bubbles critical for concrete durability. Through rigorous industry testing and on-site applications, XRT-DA has demonstrated the ability to improve concrete pore structure, enhance compressive strength, and maintain slump stability without compromising physical properties. Its unique formulation ensures excellent water dilution stability, alkali resistance, rapid defoaming action, and long-lasting foam suppression.
Concrete Defoamers Key Features:
1.Selective Foam Control:
Targets large, unstable bubbles while preserving microbubbles generated by air-entraining agents.
2.Performance Enhancement:
Improves concrete density and pore structure, leading to higher compressive strength and durability.
3.Compatibility:
Flly miscible with polycarboxylate superplasticizers, forming a stable homogeneous mixture.
4.Chemical Stability:
Resistant to alkaline environments typical in concrete formulations (pH > 12).
5.Ease of Use:
Water-dilutable without emulsion breaking or oil separation, ensuring uniform dispersion.
Concrete Defoamers Technical Specifications:
| Parameter | Specification |
|---|---|
| Appearance | Turbid oily liquid |
| Active Matter Content | ≥95% |
| Viscosity (No. 2 Rotor) | 300–1500 mPa·s |
| pH Value | 6–7 |
| Ionic Type | Non-ionic |
| Solubility | Water-soluble |
Concrete Defoamers Application Guidelines:
Recommended Dosage:
Add 1–3‰ (0.1–0.3% by weight) of the polycarboxylate superplasticizer content.
Mixing Procedure:
Stir XRT-DA thoroughly before use to ensure homogeneity.
Incorporate into the superplasticizer solution under continuous agitation for 20–50 seconds.
Compatibility:
Compatible with all standard polycarboxylate-based admixtures.
Benefits:
Optimized Air Void System: Creates uniform, stable microbubbles for freeze-thaw resistance.
Strength Retention: Maintains or enhances compressive strength compared to untreated concrete.
Workability: Preserves slump consistency for extended periods.
Durability: Reduces permeability and improves resistance to chemical attack.
Cost-Effective: Low dosage requirement minimizes admixture costs.
Concrete Defoamers Packaging & Storage:
Packaging Options:
25 kg plastic barrels, 50 kg drums, or 200 kg steel drums.
Storage Conditions:
Store in a cool, dry indoor environment (≤30°C/86°F).
Protect from direct sunlight to prevent degradation.
Shelf Life:
12 months when stored in original, sealed containers.
Safety Information:
Non-Hazardous: Classified as a non-dangerous good per international regulations.
Handling:
Wear standard protective equipment (gloves, goggles) during handling.
Avoid contact with eyes and prolonged skin exposure.
Concrete Defoamers Applications:
High-Strength Concrete: Bridges, high-rise buildings, and infrastructure.
Self-Compacting Concrete: Complex formwork and reinforced structures.
Precast Elements: Panels, pipes, and architectural components.
Marine & Underground Construction: Where durability is critical.
