CONCRETE MIX MASTER MAKES BETTER MATERIAL PROPERTIES

摘要

If not for a family trip to his parents' native Greece in 1997, when he was a civil engineering student in Germany, concrete mix master Andreas Tselebidis would have missed his life's calling. When he returned at the end of the summer, all the thesis slots in structures had been filled. When someone suggested contacting Professor Hans Knoefel, known in Europe as the "Pope of Concrete," Tselebidis hesitated. Knoefel was reputed to be a tough grader who hand-picked his students. Tselebidis decided to contact him anyway, rather than risk graduating a year late. Knoefel accepted him. In his thesis and PhD work, Tselebidis ended up proving the case for self-compacting concrete, which was not used in Europe at the time.
