New benchmark in gypsum retardation

To ensure the desired application and end-product properties, dry-mortar and gypsum formulations need to be balanced multi-component systems in which each ingredient has to perform reliably. In this investigation, various commercially available gypsum retarders were tested for their efficiency and compatibility with numerous mix-design components. A new high-performance gypsum retarder – Retardan-200 – was found to set a new standard in retarding efficiency without demonstrating the known negative characteristics of existing technologies.
