Paper 2: Climatic Study of the Underground Archaeological Site Coudenberg

Abstract

The excavation and valorization of subterranean archaeological remains, and eventually opening a site to the public, required a proper management and conservation strategy. This strategy was based on the evaluation of the delicate balance between the requirements for public health and safety, and the protection of the archaeological remains from future degradation. Controlling the climate can be essential for a preventive conservation strategy, which can be defined as an indirect action to increase the life expectancy of the archaeological remains, and by doing so keeping them in a preferred state of conservation to mitigate damage and/or deterioration.

Potential risks and possible interventions are outlined to avoid climatic conditions which are in conflict with the requirements for the visitors’ comfort while preventing damage phenomena to the materials.     

Paper 6: Grouting Mortars for Fragmented Bricks and Repair Mortars for Tiles in the Archaeological Site Coudenberg

Abstract

Different grouting and repair mortars were developed and evaluated for the conservation and restoration of fragmented bricks in the walls and floors of the remaining cellars underneath the Aula Magna, the palace’s main banqueting hall, and to fill the lacunae and perform edge repairs of red and blue-grey ceramic floor tiles in the remaining cellars underneath the chapel of the former Palace of Coudenberg in Brussels, Belgium.

To prevent the deposition of lime bloom at the surface of the masonry and to achieve an acceptable colour match of the grout in harmony with the bricks of the Aula Magna, the effect of brick powder added to natural hydraulic lime was studied. The pozzolanic properties and colour match of several historic and modern powdered bricks were investigated. Surprisingly, ancient bricks do not seem to possess higher pozzolanic properties than the more modern ones, although it is supposed that they were fired at lower temperatures. Additional evidence for the pozzolanic reaction of the different brick powder materials was obtained from a simple visual observation of stored samples. After eight weeks all of the samples containing brick powders, fired at low and high temperatures, added to putty lime had hardened under water and were transformed into a remarkably tough material. These results are important, as modern bricks are readily available in large quantities and different colours, which are hence in favour of being used instead of historical material from the site.

For the repair of the ceramic floor tiles different mortars were investigated with mixtures containing talcum, stone or brick powder, pigments, and chalk added to an epoxy binder. The mortars were tested in the laboratory and in situ for their workability and resemblance with the historic floor tiles. The finished mortars showed excellent aesthetic properties with the tiles in situ and good properties to prevent further loss due to human interaction.     

The Conservation and Degradation of Archaeological Soil Features in Flanders and Brussels: The example of Watermaal-Bosvoorde

Ten years ago, an extensive literature study on the conservation and degradation of soil features in Flanders was conducted. The outcome was a report discussing the state of preservation. The present contribution intends to synthesize the chief outcomes of that research and to present a case study where the theoretical knowledge and recommendations then put forward have been applied.     

Paper 5: Historic Mortars from the Coudenberg Archaeological Site: Characterization and Source of Raw Materials

Abstract

The characterization of historic mortars by means of a concise methodology of material analyses can provide crucial information with regard to the origin of the raw materials and the ancient mortar technology. For the analysis of the historic mortars of the Coudenberg archaeological site, the methodology consists of optical and scanning electron microscopy, simultaneous thermal analysis, and an acidic treatment. These analyses were carried out on a total of seventeen samples lifted from various areas in the site, in function of the building chronology resulting from a historic built investigation. The type of binder and aggregate as well as their volumetric ratio were determined.

Both binder and aggregate present distinctive features, which made it possible to identify the probable geological provenance of the raw materials. The observations are verified with available historical records regarding the construction of the main banqueting hall — the Aula Magna — and the use of raw materials such as limestone and sand for the production of lime and construction purposes.     

Paper 4: Mechanical Properties of Bricks of the Coudenberg Archaeological Site in View of a Proper Conservation Strategy

Abstract

Archaeological sites are essentially submitted to decay phenomena inherent on their history as well as the environment to which they are exposed after excavation. The history of such archaeological sites is particularly related to their long-term underground conservation conditions during which they were subject to salt migration into the architectural remains. This paper describes the results of drill resistance measurements using a drill resistance measurement (DRMS) device to evaluate the mechanical damage resulting from salt crystallization pressures. Further tetraethoxysilane (TEOS) was applied on powdered bricks of often moist archaeological remains. It was noticed that TEOS serves as potential nutrient for present moulds. The mechanical consolidation effect was evaluated by comparing the hardness profiles after treatment with the reference ones. Bricks used for the construction of the Aula Magna, situated underneath the Royal Square, are characterized by severe patterns of fissures for which the damage diagnosis was built up.

The Management of the Maritime Archaeological Heritage in the Bailiwick of Guernsey: a Case Study

Guernsey and the other islands in its Bailiwick have been visited and settled by people arriving by sea for thousands of years. Guernsey Museum manages the display and interpretation of this maritime heritage and, in conjunction with the Receiver of Wreck, administers the legal protection of historic wreck. Over the last 25 years a considerable amount of research has been undertaken on many aspects of the islands' maritime past. Museum displays and media presentations have been made to disseminate information about the islands' maritime archaeology to the wider world. This paper will highlight the various aspects of maritime archaeology in Guernsey and illustrate how Guernsey Museum manages this rich archaeological resource.

Site formation processes in caves: The Holocene sediments of the Haua Fteah,Cyrenaica, Libya

Caves have yielded some of the most globally important archaeological sequences, but often their interpretation has suffered from assumptions about cave sedimentary processes. Caves contain distinctive sedimentary environments: this has major implications for the understanding of contained archaeological materials. This paper describes and analyses the Holocene sediments in the Haua Fteah, a sequence regarded as essentially continuous by the original excavator. 50 years after it was first excavated, the Haua's Epipalaeolithic to post-Classical chronological range and rich finds make it still the key Holocene archaeological site in North Africa. The reassessment shows, however, that the sequence is strongly discontinuous and this has major implications for the reinterpretation of the site, as the highly-resolved archaeological record is thus likely to reflect a series of brief occupations, rather than continuous human activity. As with many caves, the sedimentary record in the Haua Fteah is an extremely sensitive indicator of environments and processes in the wider landscape. Secure understanding of sedimentary process, from analysis of the highly individual records found in caves, is essential for full understanding of their contained archaeology.     

The Armoured Cruiser HMS Defence: a case‐study in assessing the Royal Navy shipwrecks of the Battle of Jutland (1916) as an archaeological resource

This paper presents the findings from a survey of one of the shipwrecks of the Battle of Jutland, and is extracted from a longer currently unpublished report which examines the six known Royal Navy wrecks. While all of the wrecks yielded unique insights into the battle, Defence was a particularly surprising case. The extant remains of this wreck showed for the first time how the ship was destroyed and explains what some eyewitnesses reported at the time. Intact and unsalvaged, it is a source of much valuable archaeological and historical data. © 2012 The Author

The Clash of Interests: Commerce and the Politics of Trade in the Age of Anne

This article celebrates the contribution which Professor Holmes made to the field of British politics and society by the study of an important collection of political tracts. The compiler of the collection is identified as Sir Charles Cooke, one of the most significant commercial politicians of his day. The organisation of the collection illuminates the ways in which City politicians used various channels of information, both printed and personal, to support their political platforms. It also demonstrates how Cooke contributed to the defeat of the tories over the French Commerce Bill of 1713, by supplying key sources to combat the ministry's position. On a wider plane, although it suggests that partisan politics tainted all information advanced in the public sphere, this did not relieve political rivals of the need to establish the superior authority of their sources, and political success only saw Cooke redouble his efforts to gain as wide a base of information as possible. Statistical precision remained elusive, but his archive stands testament to a growing need for authority of source in a political world of party and vested interests.
