How to Select the Right Air-Entraining Admixture for High-Performance Mortars

Choosing the right technology can significantly improve mortar performance, productivity and sustainability.

The performance of modern mortars depends on much more than cement and aggregates. Today, air-entraining admixtures play a fundamental role in improving workability, reducing density, optimizing water demand and enhancing the application characteristics of industrialized mortar formulations.

However, not all air-entraining technologies deliver the same performance.

Selecting the right solution requires understanding how each technology interacts with the cementitious system and how it influences the final properties of the mortar.

At Polytrade, we have developed a portfolio of natural resin-based admixture technologies engineered to address different formulation objectives while providing consistent and sustainable performance.

Why Air Entrainment Matters

A properly designed micro-air void system offers several advantages:

  • Improved workability
  • Better mortar consistency
  • Reduced density
  • Increased mortar yield
  • Easier application
  • Lower water demand
  • Improved freeze-thaw resistance (when applicable)
  • Optimized cement efficiency

The key factor is not simply increasing the amount of entrained air, but creating a stable and homogeneous micro-air void structure.

This is where technology makes the difference.

One Technology Does Not Fit Every Formulation

Many manufacturers still use a single air-entraining agent across all mortar formulations.

In reality, each application has different technical requirements.

Some formulations require:

  • maximum mortar yield;

others require:

  • higher compressive strength;

while others prioritize:

  • workability;

or

  • formulation cost optimization.

For this reason, Polytrade developed a complete platform of complementary technologies rather than a single product.

  • renewable raw materials
  • bio-based chemistry
  • consistent air-void systems
  • reduced environmental footprint
  • excellent compatibility with cementitious systems

Selecting the Right Product

Instead of asking:

“What is your current air-entraining agent?”

Polytrade starts by asking:

“What performance do you want to achieve?”

This approach allows our technical team to recommend the most suitable technology according to:

  • formulation type
  • production process
  • desired air content
  • density target
  • strength requirements
  • application method
  • cost objectives

Technical Validation

The Polytrade admixture platform has been evaluated through laboratory studies based on internationally recognized methodologies, including:

  • air content
  • density
  • compressive strength
  • workability
  • water demand
  • microstructure evaluation
  • mortar consistency

These studies provide the technical foundation behind every solution within our portfolio.

Conclusion

Selecting an air-entraining admixture should never be based solely on dosage or price.

The most successful formulations are achieved by selecting the technology that best matches the desired performance.

At Polytrade, our natural resin technologies allow formulators to optimize productivity, sustainability and technical performance while maintaining formulation flexibility across a wide range of mortar and concrete applications.
