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.
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)
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
