The integration of finite element method (FEM) into the least-squares adjustment presented in is further extended for a joint evaluation of an elastostatic model and displacement field measurement. For linear solids which obey the Hooke's law, the material parameters determination from measurements is being examined.
Hard materials consist of a hard phase embedded in a metallic binder. In order to achieve high toughness and strength, it is necessary to have a perfect mixing of hard phase and binder, which is mainly achieved by ball milling. Niobium carbide (NbC) has a high potential to substitute tungsten carbide as hard material.
The publication presents the development of stable homogeneous and de-agglomerated NbC-dispersions. To prevent agglomeration of the powder, stable suspensions were achieved by surface treatments with the dispersants (PD and HD), which resulted in a charge reversal from a negative to a positive zeta potential. This surface-modified powder guaranteed a stable re-dispersion in the binder suspension. Nickel powder was added as metallic binder. This suspension was suited for 3D-printing. The green samples could be sintered in vacuum or Argon atmosphere.
Microbial induced corrosion (MIC) is a crucial problem in many technical plants as well as fuel tanks, leading to considerable damage and huge financial losses. Successful prevention of MIC requires the localization of first signs of corrosion as well as the identification of factors influencing the corrosion process. In this respect, also the determination of corrosion rates can be of interest for the possible prevention of MIC. Hence, there is a growing need for sensitive and preferably inexpensive tools that enable the early detection of MIC. Of special interest are methods, which provide spatially and time-resolved information and allow the study of changes on metal surfaces as prerequisites for a more detailed analysis of ongoing corrosion processes at a MIC-affected site.
Biofilm formation can lead to changes in pH, oxygen and chloride concentration as well as to the release of certain metal ions like Fe(II) and Mn(II) depending on the type of metal surface involved. Hence, optical methods enabling the detection of these analytes at very low concentration and monitoring of their changes can be used for MIC detection. Here, we propose to utilize polymeric nanosensors for MIC detection via the determination of the local pH value changes in different biofilms. Such nanosensors are known to have several advantages in imaging applications such as intracellular pH measurements including the ease of doping or labeling with a multitude of analyte-responsive and inert dye molecules for the realization of a high analyte sensitivity and ratiometric sensing. Moreover, they can be surface functionalized with target-specific ligands e.g., lectins, for the specific binding to the outer surface of certain types of bacteria. In this respect, different polymer architectures will be studied to identify an optimal candidate in terms of imaging performance in conjunction with several classes of pH-responsive fluorescent dyes like cyanines, aza-BODIPYs, and xanthenes, utilizing different mechanism of signal generation such as photo-induced electron transfer or protonation-induced changes in the spectral position of absorption and emission spectra.
Current pollen screening information networks are based on time-consuming, microscopic determination of the genus-specific pollen morphology. Additionally, the given information relies on prediction of plant growth, wind direction and seasonal information.
Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) was introduced for rapid analysis of complex biological samples. MALDI-TOF provides the possibility to measure species-specific mass peak patterns of pollen and offers a powerful tool for investigation of taxonomic relations.
Our objective is to develop a fast, reliable, routine method for detecting single pollen grains in pollen mixtures. The obtained spectra are analyzed by multivariate statistics.
The controlled production of supramolecular aggregates formed by the self-assembly of dendritic amphiphiles is of great interest owing to their potential application in the fields of nanotechnology and nanomedicine. Dendritic amphiphiles as building blocks offer the advantage that their structure and size can be precisely tuned through organic synthesis. This synthetic flexibility enables the fine-tuning of the hydrophobic to hydrophilic ratio of the dendritic segments, which mainly controls the morphology of the self-assembled structures.
A promising method for the controlled preparation of supramolecular assemblies is based on the use of micromixers.[5,6] Due to their mixing times in the range of milliseconds at the microscale level, the application of such microfluidic systems benefits from a high mixing efficiency, a low mixing time and a reproducible synthesis compared to conventional batch-based techniques such as the solvent injection method or the film hydration method.
Herein, we report on the microfluidic-assisted self-assembly of several dendritic amphiphiles and the impact of the mixing parameters on the self-assembly process.
The use of high-performance concretes holds great promise for many structural applications. This paper investigates the performance of these materials when used in combination with traditional reinforcing bars. An improved understanding of failure during reinforcing bar pull-out from high-performance concretes is needed in order to better predict the embedment length required to develop full reinforcing bar pull-out strength and the required thickness of reinforcing bar cover for adequate corrosion protection. The cracking structures surrounding the reinforcing bars were analyzed using x-ray computed tomography (CT) in order to determine the stress states causing failure. This was accomplished by conducting in-situ reinforcing bar pull-out experiments during CT scanning. A conventional concrete, a high-strength concrete, and a high-strength fiber reinforced concrete were all tested during the experiments. The results of these experiments showed that the levels of brittleness of the different concrete materials had a major impact on the failure mechanisms that they experienced during reinforcing bar pull-out. It was also clear that the specimen geometry and the casting method had a major impact on fiber orientation. The inclusion of fibers within concrete was also found to significantly improve strength and corrosion protection during reinforcing bar pull-out.
High resolution in situ monitoring of the initial cement hydration influenced by organic admixtures
(2015)
Numerous admixtures are used in the building practice to customize the properties of the cement paste during application. The influences of admixtures on the course of cement hydration and formation of hydrate phases have to be considered. Polycarboxylate ether (PCE) based polymeric superplasticizers (SPs) are known to retard the setting of the cement paste. The extent of the retardation differs depending on the molecular structure of the SP. Additionally, the presence of a stabilizing agent (SA) in the cement paste has a retarding side effect on the setting. The initial cement hydration processes and the detailed mechanisms of the retardation influenced by PCEs, as well as their interactions with particular SAs, are insufficiently understood. Up to now, only the results of phenomenological studies were taken into account to describe this retardation process. A detailed structure analysis monitoring the change of the phase composition during the hydration was never applied. Both SP and SA affect the adsorption of the sulphate ions on the clinker particles, causing changes in the formation of ettringite during the initial hydration, and are therefore a crucial part of the setting process itself. Here, the initial hydration of cement influenced by the interaction of SP and SA was monitored in situ by synchrotron X-ray diffraction. The high time resolution of the measurements allowed a continuous detection of the hydrates formed. The hydration was followed from the starting point of water addition and for couple of hours afterwards. The hydration of the levitated cement pellets containing starch as SA was initialized by adding aqueous solutions of different commercial SPs. Changes in the ettringite formation were detected in comparison to the reference hydration of pure cement.
Zur Planung und Durchführung umfangreicher Sanierungs- und Umbaumaßnahmen im Pergamon-Museum Berlin bestand die Erfordernis einer Bauzustandsanalyse an antiken Baudenkmälern. Bestandsunterlagen waren unvollständig vorhanden bzw. fehlten. Hieraus ergab sich die Notwendigkeit des kombinierten Einsatzes zerstörungsfreier
Prüftechnik.
Ultra High Performance Concrete (UHPC) is characterized by high strength and high durability. This is achieved by an optimized grain size distribution, especially within fine grains, and addition of superplasticizer, which allow the reduction of the water/cement ratio in the cement paste and thereby the increase of the density of UHPC. Thermal treatment, i.e. curing at elevated temperature and pressure, contributes to a further increase of compressive strength. The aim of the presented study was to analyze the effect of thermal treatment at 90 ◦C and atmospheric pressure on UHPC samples. Varying factors were the age of the samples when heat treatment started (initial storage time), the duration of heat treatment and the type of heat treatment. It was applied in three ways: 1. treated without any protection, 2. sealed in plastic foil and 3. treated in hot water. Afterwards the samples were analyzed with respect to their mechanical properties and their phase composition. Furthermore, the weight (water absorption) of the samples was observed over 28 days and was correlated with the strength test results. The development of strength depends on the combination of initial storage time and the duration of heat treatment and is also influenced by the type of thermal treatment. The highest compressive strengths have been observed by implementing the hot water treatment. Thereby the weight of the samples increase due to additional absorbed water. This enables an increased hydration of cement clinker inducing a higher strength.
Lightweight granules are mineral, spherical and porous particles with bulk density less than 2000 kg m . New types of lightweight granules are made from masonry -3 rubble as an alternative to the commonly used expanded clay and shale. They are produced in a multistage manufacturing process by thermal or hydrothermal treatment. Studies of the microstructure of the new lightweight granules are very important to optimise the engineering properties with regard to different applications from lightweight concrete to planting substrates and wastewater treatment. Here, the results of porosity and pore structure measurements are presented. Characteristic samples with different bulk densities of both thermally and hydrothermally hardened granules have been analysed by means of various methods.
Leichte Gesteinskörnungen mit Kornrohdichten < 2 g/cm³ werden industriell aus natürlichen Rohstoffen, wie Ton und Schiefer, hergestellt. Dabei fallen hohe Energiekosten an, während außerdem fortwährend die Verfügbarkeit geeigneter Rohstoffe sinkt. Eine Alternative stellen Leichtgranulate, die aus mineralischen Bau- und Abbruchabfällen hergestellt werden, dar.
Im Forschungsprojekt „Aufbaukörnungen“ wurde eine Technologie zur Herstellung hochwertiger leichter Gesteinskörnungen aus Mauerwerkbruch entwickelt. Ziegelhaltige Bau- und Abbruchabfälle fallen in Deutschland mit bis zu 26 Mio. t pro Jahr an und weisen größere Verwertungsdefizite als Betonbruch auf. Der neuen Verwertungsstrategie liegt die Idee des rohstofflichen Recyclings zu Grunde.
Die leichten Gesteinskörnungen werden am Ende eines mehrstufigen Herstellungsprozesses durch thermische oder hydrothermale Erhärtung im Labor- und halbtechnischen Maßstab produziert. Für Herstellungstechnologie und Eigenschaften der Leichtbetone sind neben Kornfestigkeit und Rohdichte die Porosität und Wasseraufnahme der leichten Gesteinskörnungen entscheidende Größen, die wiederum von Kornform, Oberflächenrauigkeit, Sinterschale und Porenstruktur der Körnungen beeinflusst werden.

Worldwide, cement and concrete experts are at the cutting-edge to sustainable, green, healthy but nonetheless high-Performance concrete. The current relatively low development of the cement and concrete industry in Africa offers the unique opportunity to start directly on the best achievable and sustainable Level, if only Expertise is sufficiently available. It should not be neglected that concrete is a product with comparably low Transport ranges, which means that an improved concrete market will mainly Support the local economy without exceeding financial Drains to the international market, thus fostering the fight against poverty, which is an urgent Need in most African countries.

Im Hinblick auf eine nachhaltige Entwicklung sollen nach dem KrW/AbfG der Rohstoffeintrag und der Abfallaustrag in den Lebensphasen eines Bauwerks durch weitgehende Verwertung von Sekundärrohstoffen (Reststoffen) möglichst gering gehalten werden. Ein Einsatz von Reststoffen wie Hausmüllverbrennungsaschen (MV-Aschen) im Betonbau kann potenziell einen wesentlichen Beitrag zur nachhaltigen
Entwicklung leisten.
Untersucht wurde der Einfluss der Applikationsart (konventionelle und gespritzte Herstellung, Wasserlagerung bis zur Prüfung), der Einfluss von Fasern (konventionelle Herstellung, Wasserlagerung bis zur Prüfung) und der Einfluss von Schwindreduzierern (konventionelle Herstellung, Luftlagerung bis zur Prüfung).
Modern CO2-reduced power plants with Oxyfuel-Combustion operate with gas compositions of high CO2 partial pressure and steam (Boiler, Recycling). The corrosion process occurring under such service conditions is different from that under current conditions with air combustion. The effect of temperature, pressure, chromium content on the corrosion reaction of typical power plant steels in CO2 -H2O and CO-H2O-O2 was investigated.
Beim bispektralen Verfahrensprinzip (auch 2-Monochromatoren-Methode genannt) zur Charakterisierung fluoreszierender Reflexionsproben wird das Probenmaterial monochromatisch bestrahlt und für jede dieser anregenden Wellenlängen das emittierte Spektrum monochromatisch gemessen. Dies hat gegenüber einer polychromatischen Anregung (z. B. Normlichtart D65) den Vorteil, dass spektrale Materialfunktionen (Gesamt-, Reflexions- und Lumineszenz-Strahldichtefaktoren sowie das Lumineszenz-Anregungsspektrum) und diverse Farbmaßzahlen (Sicherheits- und Kontrastfarben; Referenzmaterial) für beliebige Anregungsspektren (Normlichtarten) bestimmt werden können.

Modern municipal solid waste incinerator plants produce bottom ashes, which are used in building industry, especially as base course in road constructions. Because of a highly sophisticated reprocessing technique, the ashes Show a relatively stable composition, comparatively well defined properties and environmentally relevant Parameters below legal Limits. Due to its chemical and mineralogical characteristics, the bottom ash can in principle be used as Aggregate in the production of normal strength concrete. However, if the ash contains concrete damaging components Recycling becomes problematic.
To assess the use of municipal solid waste incinerator bottom ash (MSWI bottom ash) as Aggregate in concrete, different additionally treated ashes were chemical and physical characterised. Furthermore, concrete specimens with bottom ash as aggregates were produced and their Engineering properties were studied.
Holzschutzmittel gegen den biologischen Angriff von Insekten, Pilzen und Bakterien besitzen eine erhebliche volkswirtschaftliche Bedeutung. Zur Vermeidung einer in der DIN EN 252 beschriebenen rein visuellen Beurteilung wurde 1996 durch die BAM auf Grundlage des in der DIN 52186 enthaltenen Biegeversuchs eine alternative Strategie vorgeschlagen. In weiterführenden Untersuchungen soll ergänzend zur Prüfmaschine die Stereo-Fotogrammetrie als optisches 3D-Messverfahren eingesetzt werden. Die Entwicklung eines möglichst objektiven und technisch einfachen Nachweisverfahrens der Schutzwirkung und die vergleichende Bewertung der Aussagekraft beider Normen sind von besonderem Interesse.
Processed building rubble containing about 90 % of crushed concrete can be used as recycling aggregates. The reuse for the production of new high-grade concrete requires a knowledge of the engineering properties as well as the pore structure of These materials. Two recycling aggregates and the concretes made with them were studied.
Inorganic-organic nanocomposites are synthesised from polyethylene glycol with an average molar mass of 600 g/mol containing colloidal silica (silicic acid) and diphenyl methane diisocyanate as compact and foamed materials according to the European patent EP1414880. Beside the macroscopic properties, the pore structure and the structure of the polymer matrix of the silica/polyurethane nanocomposites with varying silica contents were studied.
Ultra-high performance concrete (UHPC) is characterised by compressive strengths above 150 MPa and an outstanding durability. These properties are achieved by optimisation of the mixture composition, the mixing procedure as well as the curing conditions of the concrete. Heat curing as well as the use of vacuum mixers may contribute to the high strength. The very high brittleness of UHPC can be compensated by the addition of steel or polymer fibres.
UHPC is produced using a very low water/cement ratio of 0.25 or smaller in combination with adding of polycarboxylate ether based superplasticisers. Furthermore, finest cements with contents of 500 kg/m³, defined selections of coarse and fine aggregates with a maximum grain size between 0.5 and 8 mm and fine pozzolanic (silica fume, fly ash) and inert additives (quartz filler) are used. In doing so, the aim is to obtain a very high packing density of the cement paste matrix and the aggregate/paste interface while a very homogeneous microstructure with a high calcium silicate hydrate (CSH) portion is formed.
In the case of optimal mixing and curing conditions, UHPC contains almost no pores and microcracks. Therefore, studies of porosity and pore structure are very important to characterise UHPC materials in connection with the mixture optimisation. Here, the experimental results for UHPC are presented in comparison with those of high-strength concrete (100 MPa) and normal-strength concrete (35 MPa), respectively.
Im Rahmen eines DFG-Forschungsvorhabens (FOR 537) wird ein Teilprojekt an der BAM bearbeitet. Ziel dieser Arbeit ist die quantitative Beschreibung und Bewertung des Korrosionsfortschrittes an Stahlproben mit kleinen Kathodenflächen (Eigenkorrosion) mittels elektrochemischer Messungen. Für die Untersuchungen wurden Betonproben mit eingebetteten Stahlelektroden hergestellt. Dabei wurden gezielt betontechnologische Parameter variiert. Dabei ist der Beton als Elektrolyt zu betrachten. Nach bestimmten Zeitintervallen werden die Betonproben aufgebrochen und die eingebetteten Stahlelektroden durch visuelle Inspektion und anschließende Bestimmung des Masseverlustes bewertet. Zur Charakterisierung des Betons (Elektrolyt) dient das Verfahren der Quecksilberporosimetrie. Mit dem Verfahren lassen sich die Zusammenhänge zwischen den betontechnologischen Parametern und der Porenstruktur aufzeigen und mittels der umfangreichen Variation der Betonparameter die Auswirkung auf den Korrosionsfortschritt nachweisen.
Ultrahochfeste Betone (UHPC) sind durch Druckfestigkeiten > 150 MPa und eine besonders hohe Dauerhaftigkeit gekennzeichnet. Ihre Herstellung gelingt durch die Optimierung der Mischungszusammensetzung, des Mischprozesses und der Nachbehandlung. Maßnahmen dazu bestehen in der Verwendung feinstgemahlener Zemente, puzzolanischer und inerter Feinststoffe, dem Einsatz gezielt ausgewählter grober und feiner Gesteinskörnungen, der Reduktion des Wasser/Bindemittel-Wertes bei Zugabe von Fließmitteln auf Polycarboxylat-Basis sowie einer Wärmebehandlung der Betone.
Das Ziel dabei ist es, eine möglichst hohe Packungsdichte in der Bindemittelmatrix bei Ausbildung einer sehr gleichmäßigen und extrem dichten Gefügestruktur mit einem hohen Anteil an Calciumsilicathydrat-Phasen zu erreichen. Deshalb sind Untersuchungen zur Porosität und Porenstruktur ein wichtiger Bestandteil zur Materialcharakterisierung im Rahmen der Mischungsoptimierung. Die Ergebnisse der Mikrostrukturuntersuchungen werden im Vergleich zu denen an einem hochfesten Beton und einem Normalbeton betrachtet.
Im Rahmen von MICROCON, einem europäischen CRAFT-Projekt,
besteht eine wesentliche Zielsetzung in der Optimierung von selbstverdichtendem Beton (SVB) im Hinblick auf Kosten und Leistungsfähigkeit durch den Einsatz von teilweise puzzolanischen Microfillern. Um die Puzzolanität bei der Beurteilung besser bewerten zu können, wird ein Referenzbeton benötigt, der aus weitestgehend inerten Zusatzstoffen besteht. Die Entwicklung eines solchen Referenzbetons fand an der BAM nach der japanischen Methode nach Okamura statt.
Ziel der Untersuchungen war es, herauszufinden ob die Druckfestigkeit hochfester Betone zerstörungsfrei mit dem Rückprallhammer PROCEQEQUOSCHMIDT durch Ermittlung des klassischen Rückprallwerts R in Kombination, mit einem aus der Untersuchung von Metallen bekannten neuen Messwert L mit ausreichender Sicherheit beschrieben werden kann.
Die Regelwerke (RL SIB, ZTV-ING) setzen für die Instandsetzung mit Betoninstandsetzungssystemen vergleichsweise hochwertige Betonuntergründe voraus. Speziell bei älterenWasserbauwerken sind oftmals nur geringerfeste Betonuntergründe vorhanden für die es bis jetzt keine geeigneten und geprüften Instandsetzungssysteme gab. Grundlage für die Entwicklung solcher Systeme sind entsprechende Referenzbetone als Untergrundbeton für die Verbundkörperprüfung.
Der Filterschlamm (FS) fällt als Reststoff bei der Abwasserbehandlung des Chemiewerkes an. Er liegt als feinteiliges Granulat vor und enthält als Hauptbestandteil amorphe Kieselsäure. Damit eröffnet sich die Möglichkeit, ihn wie einen mineralischen Zusatzstoff bei der Beton- und Mörtelherstellung zu verwenden.
Als Betonzusatzstoff werden fein aufgeteilte Zusätze zum Beton bezeichnet, die durch chemische und/oder physikalische Wirkung die Betoneigenschaften beeinflussen, und die als Stoffraumkomponente zu berücksichtigen sind.
Recyclingzuschläge (rezyklierte Gesteinskörnungen, Betonsplitt) werden großtechnisch aus dem Material, das beim Abbruch von Betonbauwerken anfällt, hergestellt. Sie bestehen zu mehr als 90% aus Altbeton. Die Wiederverwendung dieser Materialien zur Herstellung von neuen hochwertigen Beton erfordert umfangreiche Kenntnisse über ihre betontechnologischen und chemisch-physikalischen Eigenschaften. Zwei unterschiedliche Recyclingzuschläge und die damit hergestellten Betone wurden im Vergleich zu einem Referenzbeton mit natürlichen Zuschlägen gleicher Sieblinie untersucht.
Hochfeste Betone werden durch die Zugabe puzzolanischer Zusatzstoffe (Microsilica, Flugasche) und die Reduzierung des Wasser-Zement-Wertes bei gleichzeitiger Verwendung eines Fließmittels hergestellt. Diese Modifizierungen des Betons beeinflußen die Zusammensetzung und die Mikrostruktur seiner Mörtelmatrix.
Das Hochtemperatur-Laserprofilometer der BAM4 ermöglicht eine 3D-Formerkennung an keramischen Folien oder anderen flachen Objekten während thermischer Behandlungen wie zum Beispiel bei laufenden Entbinderungs- oder Sinterprozessen. Mit dem Lasertriangulationssensor werden das Höhenprofil, die lateralen und axialen Schwindungen und andere charakteristische Maße der Probe wie die Folienbreite und -dicke, Abstände zwischen spezifischen Merkmalen oder Krümmungen bestimmt. Somit können insbesondere auch Deformationen und Verwerfungen der Objekte sowie Schwindungsinhomogenitäten an strukturierten Objekten erkannt und mit dem Herstellungsprozess verknüpft werden.
