Dear colleagues, dear friends,

The ongoing development of construction materials, more precise analytical methods, and viewpoints from other disciplines enhanced their influence on construction and material sciences in the last years. Consequently, the knowledge about high performance materials and the possibilities for architects and structural engineers have leapt ahead significantly and will increase in the future. UHPC is one of the products that arose from this synthesis of interests, as there are new opportunities for innovative architectural designs, conductive concrete elements, photocatalytic cleaning of surfaces, self-healing potential of building blocks, smart construction materials, or new binders, to name a few. UHPC in particular has recently come to fruition as the worldwide efforts for standardisation will soon allow the regular application of this innovative material. Its widespread use will permit the design ofsustainable concrete structures such as wide-span bridges, filigree shells, and high-rise towers and opportunities for spectacular architectural designs.

Every four years since 2004, we and our retired colleague Prof. Michael Schmidt provided a forum for the exchange of knowledge around UHPC and other advances in construction material science for the scientific and civil engineering community. Since then, we have decided to introduce these symposia as HiPerMat, referring to High Performance Materials in construction, their development, and their application with a more general scope. Since the fourth instalment of these HiPerMat symposia in 2016, more than two years have passed.
So in about few months, HiPerMat 5: 5th International Symposium on UHPC and High Performance Materials, will take place, to which we would like to cordially invite all of you and your colleagues.

We would like very much to invite you to contribute and share your experience by presenting your own latest research and your experience from application in this field. As usual, your submitted abstracts will be reviewed and commented on by our esteemed Scientific Committee members. You will find more information on the following pages. This symposium will give us all the opportunity to discuss UHPC and further enhanced structural materials as a whole, giving special attention to a design suitable for these materials, and to the construction of durable and sustainable high performance structures. We are looking forward to welcome you again in Kassel - a unique place of science and arts right in the heart of Germany.

Yours sincerely,


Prof. Dr. rer. nat. Bernhard Middendorf   Prof. Dr.-Ing. Ekkehard Fehling
