‌Air-entraining Agent‌

Characteristics

1. Stable Foam Retention Time, Optimal Bubble Size, and Spacing

• Provides precise control over bubble size (ideally 20–100 μm) and uniform distribution, ensuring stable foam retention time.
• Maintains optimal bubble spacing (＞5× bubble diameter) to minimize stress concentration and enhance structural integrity.

1. Micro-Foam System with Extended Foam Stability

• Achieves foam stability exceeding 60–180 minutes, adaptable to various cement types (e.g., Portland, magnesium, and fast-setting cements).
• Reduces foam collapse and interconnected pores, forming closed spherical bubbles for long-term durability.

1. Versatile Air-Entrainment System for Diverse Concrete Materials

• Compatible with conventional and high-performance concrete mixes, including those with fly ash, slag, or other mineral admixtures.

Advantages

1. Air-Void System Protects Against Freeze-Thaw Cycles

• Microbubbles mitigate internal stress from ice formation, significantly improving resistance to freeze-thaw damage.

1. Enhanced Resistance to Deicing Salts and Sulfate Attack

• Dense bubble structure reduces permeability, minimizing chemical ingress and corrosion risks.

1. Improved Workability and Cohesion

• Enhances flowability and reduces segregation/bleeding by balancing viscosity and air content, facilitating easier placement and compaction.

1. Optimized Hardened Concrete Porosity

• Creates a uniform capillary pore network (＜50 μm), improving mechanical strength and durability without compromising density.

1. Reduced Water Permeability with Controlled Breathability

• Closed-cell bubbles lower water permeability while maintaining vapor transmission, ideal for waterproofing and moisture-sensitive applications.
