Proceedings pro076 : International RILEM Conference on Material Science - HetMat - Modelling of Heterogeneous Materials - Theme 2

The International Conference on Material Science (MatSci) offers three separate lines which illuminate the world of mineral building materials in its diversity: 2nd International Conference of Textile Reinforced Concrete (ICTRC), Modelling of Heterogeneous Materials (HetMat) and Additions Improving the Properties of Concrete (AdIPoC).

The present volume of the Conference Report deals with the modelling of heterogeneous materials. Research in the field of building materials is still characterised by a high experimental contribution. From such experiments, material laws and properties can be derived more or less generally and later they become part of the strength and durability examinations. On an international level, mostly mechanical scientists and building material scientists deal with the issues of the materials. The development during recent years shows that, due to the different methods of approach in both disciplines, solutions are developed which are partly very contradictory.

Therefore, it is a concern of the conference to bring together mechanical and building material scientists to commonly develop solution strategies, but also to discuss existing models. Especially composite materials such as concrete and masonry are complex materials. Due to their nonexistent ductility (crack formation) - but also because of their heterogeneity and, in the case of masonry, the additional anisotropy - they are a big challenge for the modelling and the required homogenisation methods to change from the microscopic to the macroscopic level. They will certainly keep science busy in the future. One scientist alone cannot solve these complex tasks, mechanical scientists and building material people need each other here. In this place, sincere thanks are given to all those who contribute to the success of the conference
