Ultra-High Performance Concrete (UHPC), one of the recent breakthroughs in concrete technology, impresses us with its high durability and a compressive strength comparable to that of steel. It permits the design of sustainable concrete structures such as wide-span bridges, filigree shells and high-rise towers and allows for spectacular architectural designs.
In 2004 and 2008, two International Symposia on UHPC took place at the University of Kassel, organized by the Department of Structural Materials and Construction Chemistry and the Department of Structural Engineering. Since then, the set of knowledge about the Ultra-High Performance Concrete has been substantially widened and its practical application has rapidly increased worldwide. New researchers and users of UHPC have joined the community and broadened the scope of its potential.
This conference as well has substantially grown since 2008. In 2012, about 130 speakers presented their impressions, research, and practical experience. It also attracted the attention of many international standardization bodies.
Even though the material is already highly developed, it is still possible to increase its potential even further using recent advancements in nanotechnology and colloidal chemistry. Nowadays, the reactions of binders can be studied at the nanoscale, synthetic nanoparticles of various oxides can significantly improve microstructure and reaction potential. This knowledge gives rise to many new possibilities that allow developing impregnable ceramics or multifunctional materials. They can, for example, carry agents for environmental protection, provide additional self-healing potential, and act as part of heating or cooling measures. As nanotechnology provides many new and auspicious approaches to improve the performance of construction materials and to open up new applications, the 3rd International Symposium on UHPC extended its focus towards nano-optimized construction materials and its recent advancements.
This additional aspect led us to establish the new conference name HiPerMat, derived from High Performance Construction Materials.
This volume thus contains more than 120 contributions from many research disciplines that are influenced by High Performance Materials and UHPC in particular: material sciences, structural engineering, environmental engineering, nanotechnology, chemistry, architecture, codification, and economy. A design adequate to the materials and to the construction of durable and sustainable high performance structures receives special attention.
