Forschungsschwerpunkte
Die Forschung konzentriert sich auf Fragen, wie sich Qualität und Nachhaltigkeit unterschiedlicher Zemente und Materialien, u.a. für Betone, bauchemische Formulierungen und Feuerfestmaterialien verbessert werden können. Im Einzelnen werden…
- Hydratations- oder Reaktionsmechanismen erforscht mit QXRD, WF-Kalorimetrie, TGA, DVS, Simulationsrechnungen, Modellierungen etc.,
- Zusammenhänge aufgeklärt bei der Interaktion der Mineralphasen mit H2O oder organischen Additiven,
- Materialien und Mischungen für CO2-neutrale Baustoffe untersucht und entwickelt,
- CO2-Bindung an klassische Ca-basierte Zemente und an Mg-Silikat Zemente untersucht.

Das Verbundvorhaben K4 zielt auf die Entwicklung eines ganzheitlichen Konzepts zur signifikanten Reduzierung der CO2-Emissionen in der Zement- und Betonindustrie ab, basierend auf den Säulen:
1) Entwicklung und Herstellung kalkarmer belitischer Klinker zur direkten Vermeidung anthropogener CO2-Emissionen (CDA),
2) 100%ige Primärressourceneinsparung durch Erschließung von RCP als Kalksteinsubstitut im Rohmehl zur Zementklinkerherstellung,
3) Sequestrierung und stoffliche Nutzung von anthropogenem CO2 durch Herstellung karbonatisierungsgehärteter Betonsteinsteinprodukte (CCU).

Mit diesem Vorhaben werden zwei wesentliche Ziele verfolgt. Zunächst soll mit einer Zeitauflösung von ca. 10 min die Entwicklung der relevanten, die Rheologie definierenden, Parameter während der frühen Zementhydratation verfolgt und evaluiert werden. Dabei spielt die Entwicklung der Oberfläche der Klinkerphasen, die Morphologie und Menge der sich bildenden Hydratphasen sowie der verbleibende Gehalt und die Verfügbarkeit an ungebundenem und rheologisch wirksamem Wasser eine maßgebliche Rolle.
