Joachim Hansen, Chairman Associate Professor, University of Luxembourg, Faculty of Science, Technology and Medicine Prof. Dr. André Lecomte, Vice-Chairman Professor, University of Lorraine, Institut Jean Lamour Prof. Dr.-Ing. Danièle Waldmann, Dissertation supervisor Professor, University of Luxembourg, Faculty of Science, Technology and Medicine Prof. Dr. Jean-Frank Wagner Professor, University of Trier, Department of Geology Dr. Claude Simon Expert, Head of Quality Management, Cimalux S.A. Preface and acknowledgements This doctoral dissertation presents the results of my investigations on the topic of “Recycling of gravel wash mud for manufacturing CO2-reduced cement”, which were realised during my PhD journey at the Institute of Civil and Environmental Engineering (INCEEN) of the University of Luxembourg. This research project was mainly carried out at the Laboratory of Solid Structures (LSS) of the University of Luxembourg. It deals with the revalorisation of an unused industrial waste product, namely gravel wash mud (GWM) and its utilisation for the conceptualisation of potential “low carbon” cements. The execution of the present project and the writing of this dissertation were carried out in the period from the 1st of September 2016 to the 10th of November 2020. My sincere and special thanks go to Prof. Dr.-Ing. Danièle Waldmann for her trust and her confidence in my actual potential and capabilities in the scientific field by offering me this unique opportunity to carry out a doctorate under her supervision. I want to express my profound gratitude to Prof. Dr.-Ing. Danièle Waldmann for her clear and continuous guidance throughout my PhD journey, her permanent availability for any exchange (very appreciated as this is not always obvious), her trust on the quality of my independent work, her constructive feedback and criticisms, her understanding for personal concerns, and her professionalism and efforts to provide an inspiring and motivating working environment. i I want to express my sincere thanks to Prof. Dr. Jean-Frank Wagner, Professor and Head of the Department of Geology at the University of Trier, for his support during the elaboration of the actual research question of this project. Furthermore, his contributions and inputs to extend my understanding of the geological origin and the mineralogy of the gravel wash muds were precious for the progress of the project. My sincere thanks and appreciations go to A-Prof. Dr.-Ing. Joachim Hansen, Professor in Engineering Science in the field of Hydraulic Engineering and Urban Water Engineering at the University of Luxembourg, and to Prof. Dr.-Ing.André Lecomte, Professor at the Department of Chemistry and Physics of Solids and Surfaces (Institut Jean Lemour) of the University of Lorraine, for their participation as Chairman, respectively, Vice Chairman in my dissertation defence committee. Their remarks and comments on the content of my PhD work during the different meetings of the thesis supervision committee (CET) and their detailed communication of their expectations on the final work were extremely valuable and allowed to improve my final dissertation. I am deeply grateful to Dr. Claude Simon from Cimalux S.A. for his willingness to participate as a member of my thesis supervision committee (CET). Without his eagerness to support this research project actively, major milestones and some of the significant findings would have been difficult or more time-consuming to reach. I consider his unique contributions by giving me access to various high sensitive and cost-intensive characterisation methods at his company’s expenses and linking me up with different topic-related experts as a key factor to the success of this project. His expertise and his suggestions were a precious contribution to the work and allowed me to clarify my doubts by bringing me back to the right track to succeed at fulfilling my research goals. ii Furthermore, I am sincerely thankful to Carlo Spina from Contern S.A. and Paul Wertz, from Carrières Feidt S.A., for the supply of various raw materials and tools used in the realisation of this research work, and their valuable inputs and feedback on the progress of my research work during our regular meetings. Especially, I am grateful to Paul Wertz for his valuable inputs and responses to diverse questions related to the current, historical and regional availability of gravel wash muds and the regional occurrence of similar products. Moreover, I would like to express my gratitude to Dr. Marcus Paul and Astrid Becker from the Wilhelm Dyckerhoff Institut (WDI) for their valuable contributions to various applied characterisation techniques. Additionally, I am grateful to Dr. Oscar Baeza-Urrea from the University of Trier and Zornitza Tosheva from the Department of Physics and Materials Science at the University of Luxembourg for providing support to the microstructural analysis. I would also like to thank my colleagues and friends from the laboratories in Campus Kirchberg of the University of Luxembourg, Gilbert Klein, Marc Seil, Claude Collé, Logan Freitas, Vicente Reis Adonis, Ed Weyer, Markus Schlienz, Ralph Reiter, Ken Adam, Cédric Bruyère, Grace Ligbado and Remi Radinovic for sharing their valuable time at countless occasions for technical support or memorable discussions as short distractions from everyday work. Special thanks go to Marc Seil and Gilbert Klein for their excellent and experienced research support capabilities in a friendly, pleasant and cooperative atmosphere. I could contact them at any time, and I always found appreciative advice and help regarding the provision of materials or tools, the appropriate setup of the experiments, the introduction to the operation of new machines and tools, and much more. Heartfelt thanks and highest appreciations go to my fellow PhD and Post-doc colleagues, Dr.-Ing. Michel Weiler, Dr.-Ing. Dolgion Erdenebat, Patrick Pereira Dias, Dr.-Ing. Gael Chewe Ngapeya, iii Lorenc Bogoviku, Hooman Eslami, Dr.-Ing. Laddu Bhagya Jayasinghe, Dr.-Ing.Thanh Tung Nguyen and Tarik Camo, for the numerous and endless rounds of discussions on professional and private matters, for the share of knowledge as well as for getting me out of my monotonous work routines throughout my PhD journey. I am also grateful to the staff members of the University of Luxembourg for their helpful administrative support, especially Simone Drees, Annabella Simon, Marielle Mabille, Mike Hansen, Shayan Weber, Inmaculada Peral Alonso, Silvia Vendetti, Berta Rato, Rita Giannini and Suzanne Biwer.

Luxembourg, 10th November 2020 Vishojit Bahadur THAPA iv Abstract The present research project “CO2REDCEM” is carried out at the Laboratory of Solid Structures (LSS) of the University of Luxembourg, in close collaboration with Luxembourgish industrial partners (Cimalux S.A., Carrières Feidt S.A. and Contern S.A.). This project aims at reducing the generation of CO2 emissions during cement production by minimisation of the use of cement clinker or its complete replacement by new binder compositions and concepts, containing novel material resources derived from local unused industrial waste products. Such a potential raw material is gravel wash mud (GWM), which occurs as a waste product from gravel mining. This clayey mud is collected from a sludge reservoir, located in the North West of Luxembourg. Currently, this waste product is landfilled without any further use. However, this prime material offers very promising properties, which require a thorough characterisation and verification before its revalorisation as a viable supplementary cementitious material (SCMs). Reusing or recycling of waste elements into goods has been among the greatest ambitions of our and earlier generations, and it will take a more important role in the future economy. One primary goal of this project is to replace the “end-of-life” concept of gravel wash mud by reusing it as new raw material. This endeavour will bring double benefit to environment as the waste is prevented from landfilling, and it is revalorised as a prime resource in another system. v This research work shares the outcomes from the assessment of the performance of the prime material GWM within the following binder concepts and binder reaction mechanisms: • The use of gravel wash mud (GWM) powders as a precursor material for the synthesis of alkali-activated binders: A “cementless” binder is synthesised by alkaline activation of processed and calcined GWM powders.

One of the major gaps in the known palaeobiodiversity of this group coincides with a global palaeoenvironmental crisis during the early Toarcian (Early Jurassic, 183 myr ago), known as the Jenkyns Event. Here we describe ophiuroid remains retrieved from a series of sam- ples from the Dudelange (Luxembourg) drill core, which spans the lower part of the Toarcian, between the top of the Pliensbachian and the onset of the Jenkyns Event. A total of 21 species are recorded, including three new genera and 12 new species. Ophiuroid diversity and abundance fluctuate in parallel with depositional facies, with lowest values coinciding with black shales. Highest diversities, including exceptional occurrences of taxa nowadays restricted to deep-sea areas, are recorded from just below the black shales, corresponding to the onset of the Jenkyns Event. Our results show that even small (100 g) bulk sediment samples retrieved from drill cores can yield numerous identifiable ophiuroid remains, thus unlocking this group for the study of faunal change across palaeoenvironmental crises.

It describes the structural and lithological features of the basin, which comprises sediments of Permian to Mesozoic age. The regional geological assessment profited from recently published information on the geology and regional tectonics, as well as from borehole data from Luxembourg and adjoining areas in France, Belgium and Germany. The paper specifically focuses on the location of major synsedimentary faults and weakness zones, which gave rise to a new conceptual model of basin structure and evolution. The total depth of the basin as well as the thickness estimates of the fault-controlled subunits are supported by the interpretation of a Bouguer gravity map. In addition, the stratigraphy of the Cessange borehole and the depositional conditions of the Luxembourg Sandstone have been reinterpreted in accordance with the new concept. Supported by numerous geological cross sections it is suggested that the TLB has developed along a SW–NE trending weakness zone above a Permian Graben in direct prolongation of the Wittlicher Senke.

  • Earliest Jurassic Patellogastropod, Vetigastropod, and Neritimorph Gastropods from Luxembourg with Considerations on the Triassic–Jurassic Faunal Turnover
    Earliest Jurassic patellogastropod, vetigastropod, and neritimorph gastropods from Luxembourg with considerations on the Triassic–Jurassic faunal turnover STEFANO MONARI, MARA VALENTINI, and MARIA ALESSANDRA CONTI Monari, S., Valentini, M., and Conti, M.A. 2011. Earliest Jurassic patellogastropod, vetigastropod, and neritimorph gas− tropods from Luxembourg with considerations on the Triassic–Jurassic faunal turnover. Acta Palaeontologica Polonica 56 (2): 349–384. The Hettangian to earliest Sinemurian Vetigastropoda, Patellogastropoda, and Neritimorpha housed in the National Mu− seum of Natural History of Luxembourg are studied. Most of the species comes from the Luxembourg Sandstone Forma− tion. This deposit formed along the southern margin of the London−Brabant−Ardennes Landmass, in a region that during the earliest Jurassic constituted a seaway connecting the Paris Basin with the epicontinental seas of the Netherlands and northern Germany. The systematic analysis revealed high diversity of the studied fauna; we identified twenty−two species, eleven genera, nine families, and six superfamilies. A new genus, Meiersia gen. nov., and three new species, Anodomaria schroederi sp. nov., Meiersia disarmata sp. nov., and Spirocirrus weisi sp. nov. are described. The fauna is dominated by pleurotomarioideans representing the genera Ptychomphalus, Pleurotomaria,andTrochotoma, and by the patellogastropod genus Scurriopsis both in number of species and specimens. The neritimorph genus Neridomus is also well represented. Among the accessory taxa, Anodomaria and Spirocirrus first appeared in the Late Hettangian of the Luxembourg area. Most of these genera show a species radiation in the Early Jurassic and are distributed over the western European epicontinental shelf, probably favoured by an east to west marine transgression which influenced wide areas from the basins of the northern Germany to the Paris Basin through the Luxembourg seaway.

  • Glossary of Stratigraphic Terms
    Glossary of Stratigraphic Terms The following glossary of stratigraphic terms includes terms that, at one time or another, have been used in publications dealing with concepts and prin­ ciples of stratigraphic classification, terminology and procedure. The preparation of the glossary has been in the work program of the International Subcom­ mission on Stratigraphic Classification (ISSC) since before the first edition of the International Stratigraphic Guide was published in 1976, but its compilation had to be sacrificed for the sake of an early publication of the Guide. The prepa­ ration of a glossary of stratigraphic terms was an important part of the plan to re­ vise the first edition of the Guide. During the early stages of the preparation of the glossary, some thought was given to include in it only terms currently in common use. It was soon realized that it would be difficult, and a possible source of controversy, to try to deter­ mine which terms are in common use and which have received only limited use or have been abandoned; and that it would be useful to earth scientists to be able to find in the glossary the meaning and origin of terms no longer in use now but which they might come across in older publications. For these reasons, many terms generally considered useless, invalid, obsolete, ill-defined, or synonymous to terms in common use and terms that have attained no acceptance and that have been used only by their authors have been included in the glossary. An at­ tempt has been made, however, to differentiate the two groups of terms by showing those in more common use in larger type and those who have received limited or no acceptance in smaller type.

  • Diagenesis of Luxembourg ... Dstone.Pdf
    Diagenesis of Luxembourg Sandstone by D.J. Korte Bachelor Thesis Applied Earth Sciences July 10, 2017 Student number: 4207637 Supervisor: Drs. M.M. van Tooren Second Supervisor: Ing. W. Verwaal Abstract Research has been conducted into the diagenesis of the Luxembourg Sandstone. Literature studies were followed by a visit to the outcrop, after which thin sections were studied. The Luxembourg Sandstone Formation has been deposited in the Hettangian and Sinemurian, both lower Jurassic ages. A sea strait connecting the Northern German Basin and the Paris Basin was located in present day Luxembourg. A tidal dominated delta deposited the weathering products form a part of the Rheno- hercynian Zone, the Ardennes, into the transgressive sea strait to create sandstone deposits. The outcrop near the village of Echternach is characterised by two rock types visible as horizontal beds and lenses: one well cemented and a less cemented sandstone. The less cemented zones tend to be better resistant to weathering and this causes the less cemented rock to overhang the cemented rock. The cemented zones have been cemented with calcite crystals and minor amounts of quartz cement. The sandstone consist of fine grained, moderately sorted, angular quartz grains with minor amounts of feldspars, opaque minerals, muscovite and zircon crystals. Detrital mudstone grains and ferroan cement were also present. The cemented rocks are classified as Lithic Arenites whilst the less cemented zones are classified as Sublithic Arenite, both have a recycled orogenic provenance. Three parameters have influenced the cementation. Firstly permeability differences caused by deposition of clay and deposition of coarser material. Paths of permeability have formed through the sediments and this favoured cementation.

    Earth-Science Reviews 72 (2005) 39–66 www.elsevier.com/locate/earscirev Baltica from the late Precambrian to mid-Palaeozoic times: The gain and loss of a terrane’s identity L. Robin M. Cocks*, Trond H. Torsvik Department of Palaeontology, The Natural History Museum, Cromwell Road, London SW7 5BD, UK Geodynamics Centre NGU, Leiv Eirikssons vei 39, N-7491 Trondheim, Norway Received 1 January 2005; accepted 15 April 2005 Abstract The old terrane of Baltica occupies the mass of northern Europe eastwards to the Urals and lies mostly to the north of the Trans-European Suture Zone. The core, the East European Craton, is thick and formed of rocks dating back to well over 3 billion yr, and Protobaltica can be identified as forming part of the supercontinent of Rodinia at about 1 billion yr ago. Following Rodinia’s break up at about 800 Ma, Protobaltica remained attached to Laurentia until it became the newly independent Baltica at between 570 and 550 Ma, with the inauguration of plate spreading to form the northern part of the Iapetus Ocean. To the south, during the Early Cambrian, Baltica was separated from Gondwana by the relatively narrow Ran Ocean. Baltica remained a separate terrane until its docking, firstly with Avalonia at the very end of the Ordovician (443 Ma), and then with Laurentia during the Silurian in the Scandian part of the Caledonide Orogeny. The terrane was much enlarged in the Vendian to include the areas such as Timan–Pechora now lying to the north as they became accreted to Baltica during the late Precambrian Timanide Orogeny.
