SITREN® SRA L 220 is a non-chloride, liquid shrinkage reducing admixture based on a polyether. It significantly reduces drying shrinkage and contractions within the matrix. Therefore, the risk of cracking is minimized.
Typical Applications
SITREN® SRA L 220 is recommended for the following applications
- HPC/UHPC (ultra high performance concrete)
- Concrete elements
- Durable concrete
- Flowable screeds
Benefits at a glance
SITREN® SRA L 220 functions by reducing surface tension of pore water and thus, decreasing the capillary pressure.
Overall, the resultant shrinkage strain is reduced.

Overall, the resultant shrinkage strain is reduced.
- Superior reduction of drying shrinkage limiting the risk of cracks, deformation and debonding
- 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
