The description of each procedure was directly provided by the participants and follows the same structure for each participant where institution identification and contact information was included. Each participant summarised the most significant data such as specimen’s size, load configuration, parameters or environmental conditions in a quite useful table. Moreover, the participants included description and close-up pictures of the creep frames construction, the support boundary conditions, and the measurement devices used. Finally, the participants provided a complete description of the specific complete creep test procedure followed.

An advanced understanding of the factors that limit the durability of shotcrete is crucial to develop tailored strategies for enhancing its service life. The main focus of this contribution is to shed light on the durability of shotcrete by revising the literature, highlighting what is missing and needs to be addressed, assessing how the knowledge about concrete durability can be transferred to shotcrete, and providing recommendations for durable shotcrete structures.

Oktober 2018, Funchal, Madeira Island, Portugal N2 - This paper discusses a new fresh concrete control system with the following structure: a rheometer measures the fresh concrete directly after the mixing process, during a short break. The viscosity and the dynamic yield point are determined by a ball rheometer. The rheological parameters viscosity and dynamic yield point describe the consistency and thus the pouring ability and consequently the quality of Self Compacting Concrete (SCC). Data collected from the measurement are the basis for an expert system which will help to readjust mixes with deviating rheology. Firstly, investigations were carried out during the development of different SCC mixtures in the COST TU 1404 Action. Secondly, investigations were done in two precast plants. A ball rheometer was installed in the respective mixers. The SCC for premium precast products was tested then during ongoing production. In addition, several test series were carried out in the laboratory of the OTH with the respective constitutive materials. During the test series, the mix designs of the well working SCC’s were modified by using a deviating water content. Subsequently, using the rheological data, water, superplasticizer or stabilizing agents were added to the mix, trying to reach proper workability again. The graphs for the changing rheological properties as a function of the respective amount of start water content and additional water dosage or admixture dosage were generated and analyzed for the mixes of the two precast plants. With this information and experience, an expert system for the mix readjustment is currently under development.

In den Leitungen treten häufig Kalkablagerungen, so genannte Versinterungen auf, die zu einem Teil- oder Vollverschluss der Rohre führen können und die Ableitung des Bergwassers be- bzw. verhindern. Zur Vermeidung von Schäden am Tunnelbauwerk sind regelmäßige und aufwendige Unterhaltsarbeiten notwendig. Ein wichtiger Einflussfaktor bei der Entstehung von Versinterungen ist der Kontakt des Bergwassers mit zementgebundenen Baustoffen, wie z. B. mit Spritzbeton. Aus dem Spritzbeton kann Calciumhydroxid ausgelaugt werden, das für den Korrosionsschutz der Bewehrung erforderlich ist, aber die Entstehung von Versinterungen begünstigen kann. Im Rahmen eines Forschungsprojekts wurden zahlreiche Mischungszusammensetzungen auf ihr Auslaugverhalten untersucht und Spritzbetonzusammensetzungen mit einem möglichst geringen Versinterungspotenzial entwickelt.
