Concrete Defoamers Overview

XRT-DA defoamer is a professional high-carbon alcohol polyether ester defoamer made for concrete admixtures, and it is widely used with polycarboxylate superplasticizer.

It removes harmful, uneven bubbles while retaining helpful air bubbles to extend concrete service life. Tested and used on construction sites, this concrete defoamer optimizes pore structure, boosts compression strength and keeps concrete slump stable with no impact on its performance.

Our special formula features good dilution stability and strong alkali resistance. It defoams quickly and provides long-lasting foam control.

Concrete Defoamers Key Features

Selective Foam Control

     It removes big, unstable bubbles and keeps the tiny bubbles from the air 

     entraining agents.

Performance Enhancement:

      It makes the concrete denser and improves its pore structure, so it becomes 

      stronger and lasts longer.

Compatibility:

    Mixes perfectly with polycarboxylate superplasticizers to form a stable blend.

Chemical Stability:

      Works well in concrete's strong alkaline environment (pH > 12).

Ease of Use:

      Mixes easily with water. No separation or oil floating, keeps well blended.

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.

◆ 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.

FAQ

1. Is it compatible with polycarboxylate superplasticizers?

     Yes. It mixes perfectly with polycarboxylate superplasticizers, causing no delamination or oil separation and causing no performance loss.

2. Does it adapt to high-alkali concrete?

      Yes. It features excellent alkali resistance, working stably in concrete with pH above 12 and enduring high-temperature alkaline conditions.

3. Does water dilution cause separation?

     No. It is easily water-dilutable, with no breaking, delamination, or oil floating, resulting in even dispersion in concrete slurry.

4. What is its core advantage? Does it weaken concrete strength?

     It realizes selective defoaming, removing harmful large bubbles and retaining useful microbubbles. It optimizes concrete pore structure, improves strength and durability, and stabilizes slump.

5. Will it lead to concrete slump loss?

   No. Field-proven stable performance ensures effective defoaming without causing slump loss of concrete.
