Aus der Frühzeit des Betonbaus

From the early days of concrete construction

On the European continent, some of the important stages of development from hydraulic mortar to tamped concrete are still associated mainly with certain names: Cointereaux stands for the production of fire-resistant, rural structures made of tamped earth that he described in his widely spread writings; through his success in using hydraulic lime to purposefully create "concrete" Vicat prompted his apologist Lebrun to continue the development and use it in buildings and bridges; Coignet, industrialist and chemist, whose entire life's work was devoted to the systemic production of tamped concrete with specific characteristics considers Lebrun's preparatory work only in a footnote. Lebrun's inclusion in the history of concrete deserves to be corrected based on the structures he built.
