Hans Kühl Medal
In honour of Hans Kühl (1879–1969), the GDCh Division of the Chemistry of Construction Materials awards the Hans Kühl Medal at irregular intervals to individuals

The Hans Kühl Medal is awarded to Dr. Gerhard Albrecht (Kobe, Japan) in recognition of his outstanding achievements in the development of highly innovative concrete admixtures, including vinyl ether-based PCEs, which represent a unique selling point for BASF worldwide, as well as a completely new cement accelerator (C-S-H-PCE) based on «nucleation seeding». Such admixtures will play a decisive and outstanding role in the future introduction and dissemination of CO2-reduced cements. As longtime Head of central development for concrete admixtures at SKW/Degussa/BASF, Dr. Albrecht has decisively influenced global concrete technology and taken it into new dimensions through significant inventions and patents.
