Air-entraining additive for portland and masonry cement

Product Description

Airalon® is an aqueous solution of neutralised hydroaromatic and fatty carboxylic acids with the following specifications:

Appearance:             Dark brown liquid
Specific gravity:        1.04 (±0.02)
pH:                            10 - 13
Foaming tendency:   Moderate

Airalon is one of the most effective air-entraining additives yet developed for use in the manufacture of air- entraining Portland cement and masonry cements.


  • WRDA PA will increase stripping strengths for quicker form or mould turn around.
  • Improve finishing times during colder months. • Accelerate initial and final sets through a range of temperatures.
  • Increase water reduction to enhance concrete strengths and higher required workability.
  • Can increase de-stressing strengths in pre-stressed applications.
  • Enhance pumpability and finishability.
  • WRDA PA does not initiate or promote the corrosion of reinforcing steel when used at the recommended dose rates.

Product Advantages

  • Proven performance
  • Stable air
  • Low addition rates
  • Economical to use
  • Easy and safe handling


WRDA PA is used in all types of pre-mix and pre-cast applications where a non-chloride, water-reducing set-accelerating admixture is required.

All types of concrete that have chloride ion restraints such as coastal applications.

Overdosing of WRDA PA will produce and increase concrete workability, air content and decrease setting time. The set acceleration effect will vary dependent on ambient temperatures, cement used, and the amount of overdose. However, provided correct curing procedures are followed, ultimate concrete strengths may be higher than a corresponding mix or standard admixture-dosed concrete.

Compatibility with Other Admixtures

WRDA PA in combination with an air entrainer can have a synergistic effect, and so increase the air content. It is highly recommended that truck trials be conducted to achieve specified air content. Please consult your local GCP representative for dosage guidelines.

WRDA PA can be used in conjunction with ADVA® range of high range water reducers. Each admixture should be added separately to the mix.

WRDA PA cannot be used in conjunction with Darex® Super 20, Daracem® or Daracem 19A.

Addition Rates

WRDA PA can be dosed at between 400 and 1,500mL / 100kg of total cementitious material. The higher addition rates will increase water reduction and acceleration, however admixture performance can depend on concrete components, job conditions, and desired performance characteristics.
