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.

It functions by reducing surface tension of pore water and thus, decreasing the capillary pressure. Overall, the resultant shrinkage strain is reduced and very low contribution to VOC (volatile organic compound) – allows to formulate final products that meet e.g. EMICODE EC1PLUS regulation. SITRENR SRA L 210 is recommended for the various applications such as Flowable screeds, Concrete floors, Durable concrete, concrete elements, HPC/UHPC.
