Hans Kühl

from Wikipedia, the free encyclopedia

Hans Kühl (born February 11, 1879 in Karlsburg , † April 23, 1969 in Berlin ) was a German pioneer in cement chemistry and building material technology .

Life

Hans Kühl was reciprocated in the Corps Hasso-Borussia Freiburg in 1899 . He studied chemistry with Wilhelm Ostwald and Max Bodenstein , where he was also in close contact with Wolfgang Ostwald . In 1903 he received his doctorate with a thesis on the kinetics of carbon oxide detonation gas and became an assistant at Bodenstein.

In 1905 he went to Hermann Passow's chemical-technical research institute in Blankenese . In 1907 he moved to Berlin-Lichterfelde and took over the cement and mortar technology institute from Wilhelm Michaëlis , which was affiliated to the Technical University of Berlin in 1922. At the Faculty of General Engineering, he was professor for chemical technology of building materials and cement and mortar science. He wrote numerous basic works in his field. He received a patent on gypsum slag cement, later also referred to as sulphate slag cement.

Since 2003, a Hans-Kühl-Medal has been awarded for outstanding achievements in the field of construction chemistry. The winners were: Alois Aignesberger, Kenichi Hattori (2003), Michael Roth (2004), Otto Henning and Dietbert Knöfel (2005), Wolfgang Wieker (2008), Hugo Rietveld and Tsuyoshi Hirata (2013).
