Concrete is by far the most produced material in the world, and reducing it environmental impact is major concern. In this project concrete recycling will be improved in order to avoid 'downcycling'. The crushing of concrete and other mineral C&D wastes will be studied, and the input and output materials characterized by state-of-the-art real-time measurement techniques. The resulting streams of materials will be used to design and produce new more circular building materials. This project is part of the Horizon 2020 EU project 'CIRCULess', in collaboration with several industries and universities in Europe.
The candidate will join the Building Materials group
group which contains 25 PhDs, 2 postdocs, 2 assistant professors, 1 associate professor, and 2 full professors. This research group works on new, sustainable, and circular building materials containing or synthesized from secondary raw materials with good chemical, physical and aesthetic properties, and added functionalities. Examples are natural fibers, fly ashes, nano-silica, aerogels, slags or recycled aggregates. Functionalities, including fire resistance, air purification, self-cleaning, high performance, and hydrophobicity, are investigated and developed for these building materials. Moreover, durability and sustainability, such as the degradation of, or leaching from, building materials when exposed to aggressive service environments, are studied. The investigations are carried out based on experimental observations and modeling.
The research group possesses a well-equipped, state-of-the-art building material laboratory for physical/chemical/mechanical/environmental treatment, testing and recycling, and has access to the structural design laboratory at the same department, and shares facilities with the sister Department of Chemical Engineering and Chemistry. The group has close contacts with the building material industry and frequently cooperating with other researchers, both domestic and international.
