Description
Addage shrinkage-reducing admixtures (SRAs) are used in the construction industry to decrease drying shrinkage and minimize cracking in concrete, mortar, grout, and repair materials.
Drying shrinkage is a common cause of cracking in concrete, mortar, grout, and repair materials, which can have a negative effect on both the durability and aesthetic qualities of buildings/structures.
The way that addage SRA works is through reducing the surface tension of water within the concrete matrix, which helps control moisture loss from the concrete during the curing process, thereby controlling both moisture loss from concrete and internal stresses during the curing process.
As a result of these actions, the dimensional stability, durability, and service life of concrete structures will be improved significantly. In addition, Addage SRA combines very well into dry concrete mix formulations as it can be used for many different types of construction applications where control of cracking and long-term performance are very important.
Key Features

- Enhances long-term durability and structural performance.
- Reduces internal stresses caused by curing of cement products.
- Compatible with most cementitious systems and admixtures.
- Improves overall quality of finished surfaces as well as their appearance.
- Conceivable to disperse easily into dry mix formulations and ready for use.
- Frame suitable for commercial and industrial applications of additive (i.e., SRA).
- Increases service life of concrete buildings.

Dosage Guidelines
The dosage will be determined based on application requirements, cement composition, and environmental conditions; however, typically the dosage for Addage SRAs will range between 0.5 and 2.0 percent by weight of the cementitious materials in the application you are using.
It is recommended to perform site trials to establish optimum dosages before large-scale use.
To achieve uniformity, Addage SRA should be incorporated during the dry mixing phase of your project and fully blended before introducing water to the entire batch.
Processing Precautions
Use clean, dry equipment for mixing; All equipment used for mixing should have a consistent mixing time for each mix; If product is to be stored or handled for long periods, it should not be excessively exposed to moisture; Always consult project-specific recommendations to ensure that you achieve optimum performance.
