Frank Schmidt-Döhl

Frank Schmidt-Döhl (* 1963 in Salmshausen as Frank Schmidt) is a German mineralogist, building materials scientist and author.

Live and act

Schmidt-Döhl studied mineralogy at the Philipps University of Marburg from 1984 to 1990 and was a research assistant and senior engineer at the Institute for Building Materials, Solid Construction and Fire Protection at the TU Braunschweig from 1990 to 2000 . From 2001 to 2007 he headed the chemistry, physics and environment department of the materials testing institute for the building industry in Braunschweig. In 2007 he was appointed to the professorship for building materials at the TU Hamburg-Harburg and heads the institute for building materials, building physics and building chemistry.

Schmidt-Döhl is a. a. with corrosion processes of components made of non-metallic, inorganic building materials, e.g. B. dissolving and driving concrete corrosion and developed the simulation method Transreac, with which the corresponding processes can be calculated. It is a process in which a chemical reaction model, transport models, models for updating the transport parameters in the corroded area and for calculating further corrosive effects are combined within a location- and time-dependent simulation ( transport-reaction simulation ).

The procedure was u. a. Used to investigate and predict the corrosion behavior of components when various solutions are attacked, to investigate the processes of loss of adhesion of gypsum plaster on concrete substrates, to investigate the corrosion behavior of grout anchors in soils with lime-dissolving carbonic acid and to investigate the chemical processes in the alkali-silica reaction of concrete. E. Rigo expanded the procedure into a probabilistic model with which the scatter of the calculated quantities can also be determined. S. Bruder expanded it to an adaptive model that can adapt to changes observed on the component. Compared to experimental laboratory tests, computational simulations can save a great deal of time when investigating corrosion processes. They can also be used to investigate details and interactions that may not be accessible in laboratory experiments.

In addition to special building materials , questions of material testing and corresponding method developments are another focus of Schmidt-Döhl's work, e.g. B. the identity check . He published a book covering the entire breadth of the field on materials testing in construction.

Schmidt-Döhl also wrote photo books of the Harz - Heide region and the Hessian mountainous region . The geomorphological development of characteristic landscape features is described in these illustrated books . He also described the probable course of the pre-glacial Bode in the northern Harz foreland, which deviates significantly from today's course and explains both the gap in the Teufelsmauer north of Thale , as well as the formation of today's dry valley southeast of Langenstein and the morphology of the Hoppelberg .
