Results are presented of an interdisciplinary research project of BAM on the moisture balance in the main cornice area of the Berlin Zeughaus. The main part of the investigations was carried out in 1994 and 1995. The quality of the prognosticated drying out process has been verified annually by means of measurements up to 2002. The depth-resolved local moisture determinations were accomplished with a microwave method developed by BAM. The moisture profiles revealed excessive moisture in the building element and reflected the slow drying process. Additionally, endoscopic examinations and chemical and physical analyses of miniature samples were carried out as well to help interpret the results. Hygrothermal data could be calculated from the quasi non-destructive tests and the parameters determined by the laboratory tests. Based on the 1995 measured moisture profile in the building element, the predicted simulation calculation indicated that a relatively long drying out process must be anticipated. Therefore the planned waterproofing sealing can at the earliest be applied to the surface of the building element in 2005. The good correlation of predicted and measured moisture profiles of the past years demonstrates the high quality of the new combination of test methods.

T1 - Laser induced breakdown spectroscopy for fast analysis of ingress profiles of ions on concrete N2 - An increasing number ofreinforced concrete structures, mainly in transportation infrastructure, sujfer from deterioration, e.g.freeze-thaw effects or corrosion. Deicing salts, which have been intensively used in the last decades, cause pitting corrosion on reinforcement due to penetration of Chloride ions. The penetration ofalkaline ions may also influence the alkali silica reaction (ASR) ofhighway structures. A comparatively new method for the application at building materials, laser-induced breakdown spectroscopy (L1BS), was used to determine element distributions and ingress profiles ofions on concrete specimens. With this method it is possible to measure directly on an optical accessible surface ofa specimen. The time neededfor sample preparation and measurement is low. With LIBS repeatable automated measurements on a large number of specimens can be carried out. The presented results show that the heterogeneity ofthe material is taken into Account and thus the errors due to the sampling is minimized. A mobile setup for on-site element analysis is presented. The paper describes the results measured on concrete samples obtainedfrom parking decks and cores taken from highways. A comparison with Standard Chemical analysis will be presented.

T1 - Laser-induced breakdown spectroscopy for fast analysis of ingress profiles of ions on concrete N2 - An increasing number of reinforced concrete structures, often components of transportation infrastructure, suffer from deterioration, e. g. freeze-thaw effects or corrosion. De-icing salts, which have beenintensively used in the last decades, may cause pitting corrosion at the reinforcement following the Penetration of chloride ions. The penetration of alkaline ions may also influence the alkali silica reaction (ASR) of highway structures. For the application at building materials a relatively new method, the laser induced breakdown spectroscopy (LIBS), was used to determine element distributions and ingress profiles of ions on concretespecimens. LIBS is a testing method which complements the Standard Chemical methods. It is able to measure directly on an optical accessible surface of a specimen. The time needed for sample preparation and measurement is low. The described setup allows repeatable automated measurements at a high number of specimens. The results presented here, show how the heterogeneity of the material can be qualified and how the errors caused by the sampling procedure can be minimised. A mobile setup is available for on site element analysis. Following the results taken at laboratory samples, concrete samples obtained from parking decks and cores taken at highways are presented. The distribution of the characteristic ions and/or the Ingress characteristic of damaging substances are determined.
