21st International Conference on Building Materials (ibausil)

21. Internationale Baustofftagung LogoBy establishing the International Conference on Building Materials ibausil in 1964, an international forum for the exchange of scientific views was created. One aim of the conference has always been to bring together science and building practice in Europe’s geographical centre. Next year’s edition, 21st ibausil, will continue this tradition.

As in the previous years, the main emphasis of the lectures is put on challenges of developing and applying building materials, accompanied by an exhibition of products and technologies. The cultural programme of the conference will provide professional excursions as well as a welcome dinner.

In 1999, Weimar was crowned as Europe’s City of Culture. The city and ist surroundings are famous for many sights and attractions. Weimar’s cultural heritage and contemporary art create an incomparable and unique flair for all participants of the conference. We guarantee you a pleasant and worthwhile stay in our hometown in September 2023.

Main topics

The main topics of the conference are structured according to materials. Methodologically-oriented contributions (production engineering, ecology, quality assurance, test methods and processings, structural condition assessment, effects of admixtures) should therefore be classified according to application. Same applies for contributions that deal with construction or revitalisation of buildings or preservation of historical monuments.
