SITREN® SRA L 210 is a non-chloride, liquid shrinkage reducing admixture based on a polyether. It significantly reduces drying and plastic shrinkage and minimizes the risk of cracking thereof.
Typical Applications
SITREN® SRA L 210 is recommended for the following applications
- Flowable screeds
- Concrete floors
- Self-compacting concrete
- Durable concrete
- Concrete elements
- HPC/UHPC ([ultra] high performance concrete)
Benefits at a glance
SITREN® SRA L 210 functions by reducing surface tension of pore water and thus, decreasing the capillary pressure. Overall, the resultant shrinkage strain is reduced.

- Superior reduction of drying and plastic shrinkage limiting the risk of cracks, deformation and debonding
- Low impact on air void content of the concrete - good workability properties
- No impact on set time and early strength development of the cement
- Improved impermeability and durability of concrete reduce maintenance and refurbishments costs
- Very low contribution to VOC (volatile organic compound) allows to formulate final products that meet e.g. EMICODE EC1PLUS regulation
- Reduced potential for slab curling
