By 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.

The city and its 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.

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 conference languages are German and English.
