Proceedings pro077 : International RILEM Conference on Material Science - AdIPoC - Additions Improving Properties of Concrete - Theme 3

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 additions to improve the concrete properties. Nowadays, the use of industrial byproducts to reduce the CO2 emission in cement production is state-of-the-art. So-called M-cements (mixtures of several components) become more and more important in the area of Portland composite cements because they optimise the physical and chemical cement properties and, at the same time, entail more flexibility and cost effectiveness. In concrete production, among others, fly ash, silica fume and limestone powder have been applied as additions for a long time. Workability, hydration heat and durability issues are in the focus. Blast furnace slag as concrete addition comes increasingly to the fore and in some countries it has already been applied.

In Germany, for instance, the application rule which enables an economic use is presently still missing. Besides there are the organic concrete additions which effect a compaction of the concrete structure or an internal curing and thus improve the mechanical and durability properties. Even the combination of concrete additions offers manifold possibilities of optimisation, e. g. at the grading curves of powder-fine materials but also of a mutual influence on the chemical reaction. The conference offers a good survey of the application of concrete additions to improve the concrete properties. In this place, sincere thanks are given to all those who contribute to the success of the conference.
