International Conference on Building Materials

21st International Conference on Building Materials "ibausil" | 13-15 September 2023 | Weimar, Germany

You may register here for 21ibausil from February 2023.


We kindly invite you to 21st ibausil in Weimar, Germany. You may find all necessary information on this website.

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. 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.

Conference Languages

Conference languages are German and English. Simultaneous interpreting from German to English and vice versa will be provided in the main auditorium, not in the other lecture halls. 

Submission of Papers

Please find the Call for Papers Flyer here.

Authors are invited to submit an abstract by solely using this form until 31 December 2022.

Each researcher should submit only one paper, but co-authorship on other papers is possible and welcome. The conference committee will decide on the acceptance of the submissions and will notify the authors by 31 January 2023. Full papers need to be submitted by 30 April 2023.

This year, the conference proceedings will be published digitally by a renowned scientific publisher, which allows DOI citations. In terms of sustainability there will be no printed version of the submissions.

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.
