Jos Brouwers - Research

 

The chair Building Materials is devoted to the advancement and diffusion of knowledge concerning sustainable and functional building materials. Novel materials is one of the key enabling technologies in the building sector. Current research interests include:

  • Sustainable building (materials, energy, water).

  • Granular mix design and concrete/mortar rheology (Self-Compacting Concrete, soil grouts, earth moist concrete, fiber reinforced concrete, oil well cement etc.).

  • Microstructure and pore water chemistry of hydrating cement/lime/gypsum and cementitious by-products (slag, fly ash etc.), and their dehydration (e.g. fire response).

  • Treatment of contaminated soils, dredged sediments, industrial waste etc, with the help of air/steam (cleaning) and by mixing with cement/lime/gypsum (immobilization/stabilization).

  • Transport properties and durability of cement/lime/gypsum based materials (e.g. Cl- and CO2 diffusion/binding).

  • Functional materials: self-cleaning, air-purifying, translucent, thermally buffering, etc.

The project: Hydration of blended cements was supported by the Dr. Ir. Cornelis Lely Foundation (Dr. W. Chen) and the sponsor group from 2003-2007.

In 2005-2009 involved in the 4-year Integrated Project (EU 6th FP): Re-engineering of natural stone production chain through knowledge-based processes, eco-innovation and new organizational paradigms (Acronym: I-STONE). The group focused on the cement-based R&D within this project: Development of High-Tech Concrete containing Natural Stone (Dr. Dipl.-Ing. M. Hunger). A related project Innovative concrete production focuses on earth-moist concrete (Dr. Dipl.-Ing. G. Hüsken). Concretes with efficient binder use and with additional functionalities (self-cleaning ability, NO degradation ability, enhanced heat buffering etc) were developed and modeled.
