Here, we present an approach to analyze changes in the phase composition due to chemical attack in the form of sulfate ingress within the microstructure. Micro-X-ray (µX-ray) diffraction using synchrotron radiation in Debye–Scherrer (transmission) geometry allowed a spatial resolution of 10 µm. Phase transformations in the wake of damaging processes were observed in a detailed high-resolution imaging study. In comparison, samples containing supplementary cementitious materials were investigated and used to reconstruct the influence of different degeneration processes in detail. Additionally, reaction fronts within the bulk were localized by micro-X-ray fluorescence analysis. The experimental setup provided the possibility for analyzing the phase assemblage of a given sample without destroying the microstructure. The specimens for phase analysis are thick sections of the primary material and can be used for further microscopic analysis of the microstructure and microchemistry, e.g., scanning electron microscopy–energy-dispersive X-ray spectroscopy (SEM–EDX) or Raman spectroscopy.

For the last three decades, sample holders based on this effect have been commonly used for contact free handling of samples coupled with a number of analytical techniques. In this study, a wall-free climate unit is presented, which allows the control of the environmental conditions of suspended samples. The insulation is based on a continuous cold/hot gas flow around the sample and thus does not require any additional isolation material. This provides a direct access to the levitated sample and circumvents any influence of the climate unit material to the running analyses.

Resource efficiency aspects such as the availability of spare parts, the ability to dismantle, etc. have been included in draft working documents in the revision of several already existing Ecodesign regulations as a first step. However, often these aspects are not consistent with the current technology and design of these products. A possible reason could be a lack of sufficient consultation or of a methodology which is sufficiently tailored for this topic. The established strategies and tools, used by policymakers, such as the Methodology for the Ecodesign of Energy-related Products (MEErP), do not seem to deal with these aspects appropriately. Draft requirements need to be very well developed before being discussed with member states and other related stakeholders, because including resource efficiency parameters could lead to additional, very wide-ranging effects on society. This topic cannot be covered well with legislative tools developed primarily for energy aspects. In this paper, a method is presented which can be used to combine products’ properties with crucial resource efficiency indicators. The method can be used to develop a set of draft legislative requirements and to pre-evaluate these requirements by target groups which would be affected by additional legal requirements. These include: market surveillance authorities, standardization organizations, manufacturers and their associations, environmental organizations and research facilities. The method incorporates stakeholders’ feedback to identify potential resource efficiency measures for materials and/or products, their impact on the European ecology, economy and society. Based on this it would help to develop legislative requirements which are feasible and desirable. The results can then be fed into the formal legislative process, probably speeding it up.

Anforderungen zu einer gesetzlich vorgeschriebenen Lebensdauer, Reparierbarkeit, Recyclingfähigkeit, etc. von Produkten sollen unter der Ökodesign-Richtlinie geregelt werden. Bei diesem Vorhaben steht der Normungsauftrag M/543 im Zentrum. Es wurde 2015 von der Europäischen Kommission vergeben und bislang sind acht horizontale bzw. generische EN-Normen geplant. Trotz der zu erwartenden hohen Reichweite dieses Vorhabens scheinen die Inhalte und der eigentliche Zweck der zu erarbeitenden Normen vielen Marktakteuren noch nicht vollständig bekannt zu sein, daher sollen im Rahmen des Webinars diese Inhalte kurz vorgestellt werden.

The Ecodesign Directive and Energy Labelling Regulation have achieved substantial energy savings since their inception. For many products, the magnitude of savings available from further tightening existing energy efficiency requirements is now often outweighed by savings that can be achieved by material efficiency requirements. Further, there are some products such as smartphones for which there are limited gains to be made in energy efficiency but for material efficiency. In the Commission’s Circular Economy Action Plan from 2015, a new direction was defined for ecodesign policy, to systematically examine considerations such as reparability, durability, upgradability, recyclability, or the identification of certain materials or substances. The Commission consequently issued a standardisation request (M/543, 2015) to the European Standardization Organisations (CEN / CENELEC / ETSI) to develop generic/horizontal standards relevant to energy-related products that address these major aspects of material efficiency. In this study we evaluate the potential contribution of these new standards (with specific focus on the standards for repair, durability and recyclability) to future developments under the European Ecodesign Directive. Opportunities for the impact of these standards to be enhanced by future work are highlighted.

We have found that in the initial stages of adsorption water molecules occupy niches close to pore walls, followed later by the filling of the central pore area. Intensified by confinement, intermolecular water interactions lead to the formation of well-ordered hydrogen-bonded water chains and to the onset of cooperative vibrations. On the other hand, the same intermolecular interactions lead to two relaxation processes, the faster of which is the spontaneous position exchange between two water molecules placed 3.2-4 A from each other. Self-diffusion in an axial pore direction is the result of those spontaneous random exchanges and is substantially slower than the self-diffusion in bulk water.

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.
