SITREN® SRA L 201 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 201 is recommended for the following applications
- Flowable screeds
- Concrete floors
- Durable concrete
- HPC/UHPC ([ultra] high performance concrete)
- Concrete elements
- Self-compacting concrete
Benefits at a glance
SITREN® SRA L 201 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
- Reduced potential for slab curling
- Good workability properties
- 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
- Fast curing - almost no influence on concrete setting and of strength
