RCRE Seminar: Recycling Strategies for C&D Waste

Biography

Prof. Jos Brouwers is a Full Professor and Chair of Building Materials at Eindhoven University of Technology (TU/e), The Netherlands. He obtained his MSc in Mechanical Engineering and his PhD in Applied Physics at TU/e. His research interests include physics of particle packing (granular building materials, and amorphisation of metals and metalloids); inorganic chemistry and mineralogy of cementitious materials; physics of suspension rheology; chemical reactions (heterogeneous, dissolution and precipitation); synthesis and application of nano-engineered materials (e.g. silica, aerogel and titania); biomaterial- cementitious composites; computational modelling of particle packing, and cementitious hydration and carbonation reactions using cellular automata; and recycling and minerals processing. Prof. Brouwers is also a Visiting Professor at State Key Lab of Silicate Building Materials at Wuhan University of Technology, China, where he focuses on construction materials and sustainable building. So far, he co-authored 255 publications in peer-reviewed journals, of which 32 single-authored, that have been cited more than 24,500 times with h- index of 80.

Abstract

In this presentation, the smart recycling of concrete is addressed. Smart recycling means new crushing and separating techniques to obtain flows of relatively pure aggregates and cement stone, whereby the latter is tried to separate further in reacted and unreacted cement. Treatment of the flows, such as their accelerated carbonation, are introduced. Besides the material and processing techniques, also new characterization methods are presented to assess the phase composition of generated flows.
