Shrinkage is defined here in the context of the volume reduction of the mortar or concrete during the drying and setting stages of hydration.
Shrinkage is defined here in the context of the volume reduction of the mortar or concrete during the drying and setting stages of hydration.
Excessive shrinkage of cement with resulting cracks and curing appearance are the most severe problems in the field of cement-based construction materials. The resulting cracks do have negative influence on the job-site quality such as:
- Appearance
- Usability of product
- Adhesion problems such as debonding
- Durability
Peramin® SRA offers the means to control the dimensional variations of cementitious binder systems in demanding applications such as self-levelling flooring compounds, screeds and technical mortars.
- Significant reduction of both plastic and drying shrinkage in drymix mortars
- Prevention of curling
- Full compatibility with other Peramin additives
Products in this range
Main application of Peramin® SRA for building chemistry
The Peramin® SRA range can also be used in combination or association with Peramin® SMF, CONPAC, DEFOAM and AXL additives.
