layer and later trained with a carpenter. She makes no secret of her examination work: a two-draft chimney, which she built herself. Did all of this predestine her to follow in the footsteps of Master Gerhard, the first medieval master builder who in turn was influenced by the most medieval of all thinkers, the scholar Albertus Magnus? It is no aesthete’s job to be master builder of the cathedral in Cologne. If one wishes, it is the application of the knowledge of the seven liberal arts of antiquity – the “trivium” (grammar, rhetoric and logic) and the “quadrivium” (arithmetic, music, geometry and astronomy). It is heavenly harmony in a very earthly house, which, thanks to its geometry, however, moves people in large and small things. Who could not be impressed, standing lost in a building that measures 400,000 cubic meters in volume? In this regard, Schock-Werner is no different to any other tourist who strides, strolls or shuffles through the cathedral. Is it the work on a gigantic facade, a kind of sham church? No, the master builder of the Dombauhütte would categorically refute this. The latest scientific research findings are used in stone conservation, for example in the acrylic impregnation process, in which stones are saturated with epoxy resin methyl methacrylate, which in turn polymerizes in the interior of the stones. She would also like to work with metallurgists to gain an insight into which of the steel alloys used are particularly resistant to the elements. There is enough room for the respective tests, high up on the towers of the stone house. In any case, the use of stainless steel is indispensable today, if new steel sections or supports are required. Paying due attention to detail in a large, indeed, gigantic concept is what the cathedral master builder regards as her task. Heavily enriched in details, stretching from the foundation right up to the tops of the towers, the restoration will never come to an end. Is this a frustrating prospect? Here, too, she ranks herself into a long-standing tradition A bridge to eternity The cathedral will never be completed, for preserving a space of 400,000 cubic meters is a never-ending task. If it is ever completed, then eternity has begun. But that can take time. TK Magazine | 1 | 2004 | MASTER BUILDER 47 in both the direct and the figurative sense: “The church in a secular world: That is the picture I have of this cathedral, and it is the picture of the church today. I want to be involved in working on this church.” At least it is not a Sisyphean task. The progress is definitely visible. For example, the war damage is becoming increasingly less obvious. A flying buttress in the choir, which was damaged during the war, was replaced with a new one. This year, the so-called “filling” will be sealed – a patched area that was covered up quickly with tiles in makeshift fashion in 1944. “A very complicated place with an intricate structure and exquisite sculptures, the restoration of which we are now bringing to a close, however.” THE CATHEDRAL MASTER BUILDER CANNOT BE A DREAMER Sisyphus, according to Camus, must have been a happy man, since he found meaning in the absence of meaning. Maybe Schock-Werner’s unruffled calm and almost Rhineland-like carefree manner has saved her from such nihilistic romancing on meaning. She has nothing against the term “conservative,” not least because of her profession, as an expert in matters of maintaining and preserving. However, her thinking is always directed toward the future, which explains her inquisitiveness in matters of materials research and stone conservation. Incidentally, if one is running an operation like the Dombauhütte, with more than 80 staff, a budget of several million euros and a considerable outward effect, like she is, one cannot be a dreamer, but must have one’s feet firmly on the ground. She does this, with verve, with the greatest conviction that the task of being cathedral master builder in Cologne is a dream profession. After all, she is working on a construction that builds a bridge to eternity and not, as Goethe wrote rather smugly, like a “fairytale of Towers of Babel on the banks of the Rhine.” 7
48 LiDONIT By Sebastian Groß | Photos Rainer Kaysers Slag isn’t refuse, but is generated in steel production,” says Michael Joost, who works in the corporate development department of DSU, Gesellschaft für Dienstleistungen und Umwelttechnik. It is part of ThyssenKrupp Services and is partly owned by the asphalt specialist DEUTAG. The new product he is talking about is called LiDonit, a word that actually has a very simple origin, despite its cryptic appearance. Joost, a trained processor, does not give the impression that he is selling an object that he knows only from hearsay, and when he says that “the devil is in the details” in LiDonit you believe him because he can explain every last thing about it, starting with the name: “LiDonit is a registered trademark created from the name of the Austrian steel works in Linz- Donawitz and the steel production process of the same name, and the Greek word for stone (lithos).” He then explains just what this trademarked product is: “A synthetic mineral substance that is generated in the smelter process in steel production, which is rich in calcium-silicate.” HOW THE MINERAL SUBSTANCE COMES TO LIFE The abstract explanation in his office in Duisburg-Ruhrort becomes tangible when, equipped with a helmet, protective glasses, heavy shoes and a protective jacket, Joost takes a visitor to the place where this wondrous mineral substance is brought to life: Steel works No. II of ThyssenKrupp Stahl AG in Duisburg-Beeckerwerth, Germany. Seeing a cast remains an impressive experience. Inside are the elementary powers of fire, which with the help of injected oxygen spark a unique flush of flame in the filled oxygen steel converter, while bringing liquid crude iron, scrap and additives to the boil. The process seems to take the observer back to the volcanic eruptions of former eons, when Driving on fine chippings LiDonit is the name of the stabilized slag that is generated in steel production. It is a sustainable product because it is used in road construction
