20th International Conference on Building Materials ibausil in Weimar

Main topics of the conference

The main topics of the conference are grouped according to materials and will deal with problems of both basic research and applied science, ranging from new buildings and revitalisation to the preservation of monuments. Methodologically-oriented contributions (production engineering, ecology, ensuring of quality, test methods and test processings, assessments of actual building state, effects of admixtures, additives and aggregates) should therefore be classified according to application.

1 Inorganic binders
10 Cement production process
11 Type of cements and cement properties
12 Cement hydration
13 Effect of admixtures
14 Binders and materials on the base of calcium sulphate
15 Special binders

The History of ibausil

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 researchers from universities and industrial enterprises, from the east and the west, together in the geographical centre of Europe.

As in the past, the main emphasis is put on problems of the development and application of building materials. An accompanying exhibition of products and procedures will also take place. In addition, the organizers intend to offer special excursions on the last day of the conference.

The variety of sights in and around Weimar and the impressive cultural heritage and contemporary works of art will make your stay in the "European city of culture 1999" pleasant and worthwhile.
