    <title language="eng">Investigation, assessment and realtime readjustment of the rheological properties of SCC</title>
    <abstract language="eng">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.&#13;
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.&#13;
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.</abstract>

    <title language="eng">Pumpability of wet mixsprayed concrete with reduced clinker content</title>
    <abstract language="deu">The research project „Advanced and Sustainable Shotcrete - ASSpC“ aims at the improvement of sprayed concrete mix design regarding durability and sustainability. One possible improvement is to replace part of the clinker content in the binder with different supplementary cementitious materials. It is crucial that new mix designs fulfil the basic technical requirements on site concerning workability and early age development, too. One central issue of the project is to&#13;
investigate which parameters influence the pumpability of sprayed concrete. Several test methods are used to determine the stability, tendency to segregation, bleeding and of course the consistency&#13;
of concrete. An essential test method is a concrete sliding pipe rheometer (Sliper). This rheometer determines the pumping characteristics of concrete in the laboratory and on construction site. In comparison to other rheometers, the Sliper evaluates the rheological characteristics of the thin&#13;
layer of paste which is lubricating the wall of the convey ing pipe. The paper presents the tests procedures in detail as well as first results from lab-tests and from site-tests with different&#13;

    <title language="eng">Durable and Sustainable Shotcrete – Requirements Concerning Workability and Early Strength Development</title>
    <abstract language="eng">Nowadays there is a special need to develop “new” construction materials to reduce the environmental footprint of structures. Investigations focus on durability of constructions and the use of sustainable materials and the reduction of CO2 emission (especially of the binder). Constructions have to be sustainable and durable. This will lead to low maintenance work and costs as well as a good life cycle performance. The aim of the Austrian research project „Advanced and Sustainable Shotcrete - ASSpC“ is to improve shotcrete mix design regarding durability and sustainability. There are different ways which may lead to success, one possibility is to replace part of the clinker content in the binder with supplementary cementitious materials. But it is crucial that new mix designs fulfil the technical requirements on site concerning workability and early age strength development, too. One central issue of the research project is to investigate how the pumpability of shotcrete can be determined in lab. At the moment there is no proven method available to measure the pumpability of shotcrete. Several test methods are used to determine the stability, tendency to segregation, bleeding and of course the consistency of concrete. Common test methods like the spread flow table and V-funnel flow time are used as well as two point test methods like the concrete rheometer eBT2 and Sliper. The segregation tendency is evaluated by the filter pressing test and the bucket setting test. Results from lab will be compared to results from site to define threshold values and parameters which describe the pumping characteristics of shotcrete base mix. In addition to that the early age strength development of the shotcrete mix design is investigated with the Minishot System designed by Sika. The shotcrete system is downscaled to a mini spray unit. In opposite to common test methods it is not necessary to mix the accelerator into the cement paste or mortar, but it will be added at the nozzle. The paste is sprayed by a downscaled nozzle and thus a realistic shear stress can be achieved. The paste is applied to a pulsment ultrasound spectrometer and the shear modulus development is measured continuously over time. The results can be linked to the strength development of shotcrete. The paper presents the tests procedures mentioned above in detail as well as first results with different shotcrete mix-designs.</abstract>

    <title language="eng">The Determination of Rheological Properties of "High Slump Concrete" and SCC - the Advantages of a Modified Online Ball Measuring System</title>
    <abstract language="eng">In this paper a new rheometer for Self-Compacting-Concrete (SCC) and High-Slump-Concrete is presented. It is installed in a concrete mixer and provides results of the rheological properties immediately at the end of the mixing process. The intention was to find a way to evaluate the rheological properties automatically in the last step of the mixing process. Therefore, the rheometer immerses in the concrete and starts the measurement. At this time a correction of the mixture is still possible, before it is filled into the truck. In a first step, a laboratory rheometer was built and the measurement procedure was developed. In a second step, the laboratory rheometer was installed in a 75 1 concrete mixer and data were collected and evaluated. The accuracy is proven by comparing test results with a slightly different mix design.</abstract>

    <title language="eng">Flexural Creep Tests on Beams : 8 Years of Experience with Steel and Synthetic Fibres</title>
    <abstract language="eng">The creep of cracked fibre reinforced concrete beams has been investigated by many laboratories. Different testing procedures have been used. Creep-test results prove that cracked beams reinforced by fibres show time dependent deformations and therefore increasing crack width with time. Some cannot sustain a high percentage of post-crack load for an extended period and fail due to creep rupture. Determination of the residual strength of FRC according to the Austrian Guideline Fibre Reinforced Concrete was the starting point for the tests. The beams were first tested under four-point flexural loading up to a deflection of 1.75 mm. The beams were then unloaded and three pre-cracked beams were loaded with a sustained load at various percentages of the load reported at 1.75 mm deflection. The used testing procedure, realized and planned improvements are discussed. Typical creep-time curves of FRC are presented. The load level was increased stepwise. Starting point was 50 % of the residual load at 1.75 mm deflection. At the load level of 60 %, beams with several fibre types started deforming faster and the test ended up in a creep failure. An alarming fact is that beams with some fibre-types may fail after 7 years of loading.</abstract>

    <title language="eng">Enhanced durability of shotcrete – Reduced potential for precipitations</title>
    <abstract language="eng">The contact of underground water with shotcrete leads to leaching of calcium hydroxide and can increase the precipitation of calcite in the secondary drainage system of tunnels under certain conditions. Indeed precipitations in the drainage pipes lead to high maintenance costs. Within a research project the leaching behavior of new and innovative binder compositions was tested in lab tests. One possible change in mix-design is the reduction in clinker content by using a lower amount of Ordinary Portland Cement together with cementitious materials. Successful combinations were further investigated in sprayed mortar and shotcrete tests to examine the influences of the spraying process and the addition of accelerator. The results indicate how shotcrete mix-design can be improved regarding its potential for precipitations and subsequently enhanced durability of shotcrete.</abstract>

    <title language="eng">Sulfate resistance of dry mix shotcretes with new binder composition</title>
    <abstract language="eng">Improved understanding of the mechanisms underlying deleterious chemical attacks is necessary to better predict the long-term performance and durability of shotcrete in aggressive environments. In the scope of the research project “ASSpC - Advanced and Sustainable Sprayed Concrete”, new durable and sustainable shotcretes and new test methods are developed. In order to increase shotcrete durability, the spray cement (specified in Austrian Guideline “Sprayed concrete”) used is substituted with supplementary cementitious materials (SCMs). However, in the past SCMs have seen only limited use in the application of dry-mix shotcrete. This contribution presents 6 new mix designs intended to be used for dry-mix shotcrete, each with varying amounts and types of SCMs, and compares their performance and sprayability with a commercially available spray cement. As sulfate attack is one of the major threats to shotcrete (e.g. in tunnelling), the resistance of the new mixes against sulfate attack is tested using a modified version of the Swiss sulfate test according to SIA 262/1:2013. This approach provides new insights into damaging mechanisms of dry mix shotcrete in sulfate-loaded environments</abstract>

    <title language="eng">"ASSpC" Shotcrete research for the needs of tomorrow</title>
    <abstract language="eng">Shotcrete or sprayed concrete in tunneling in connection with the "New Austrian Tunneling Method” has been developed over the last decades to reach a high quality standard. However, at present the development of new shotcrete mixes is required to fulfill durability and stainability requirements, i.e. for superior performance in aggressive environments and reduction of maintenance costs. In the course of the project ASSpC ("Advanced and sustainable sprayed concrete") the research team focuses on producing and testing new and innovative shotcrete mixes using local and environmentally friendly raw materials. Sustainable and durable shotcrete with optimized mechanical and physical properties and improved chemical resistance is developed.&#13;
This paper outlines the motivation for the project, gives an overview of the project structure and introduces key reaction mechanisms and environmental controls causing damage of shotcrete in tunnels.</abstract>

    <title language="deu">Dauerhaftigkeitsuntersuchungen an Trocken- und Nassspritzbetonen mit mineralischen Zusatzstoffen - Investigations on the durability of dry- and wet-mix sprayed concrete with mineral additions</title>
    <abstract language="deu">Die Dauerhaftigkeit von Spritzbeton kann, insbesondere in seiner Verwendung als Stütz-und Ausbaumaterial im Tunnelbau, durch chemische Angriffe deutlich herabgesetzt werden. Im Forschungsprojekt "Entwicklung neuer dauerhafter und nachhaltiger Spritzbetone (ASSpC)" wurden Prüfkörper von Trocken-und Nassspritzbetonen in Großspritzversuchen hergestellt. Der Sulfatwiderstand und das Lösungsverhalten der Betone in sulfathaltigen wässrigen Lösungen wurden mit drei Testverfahren bestimmt und die Ergebnisse miteinander verglichen: Ein Pulvertestverfahren zeigt die Auflösung von Zementhydratphasen zugunsten der Neubildung von Calcit und Ettringit. Das Ausmaß der Sulfatdehnung an Bohrkernen, ermittelt im zweiten Testverfahren, korrespondiert mit dem chemischen Verhalten des gemahlenen Materials, insbesondere bezüglich der Reaktivität von calcium-und aluminium-haltigen Hydratphasen. Der Thaumasitwiderstand, ermittelt über Masseverlust von Prüf-körpern, zeigte eine weitgehende Übereinstimmung mit den zuvor genannten Tests. Die Verwendung von hochreinen Metakaolinen (7-10 M-% des Bindemittels) oder Feinstcalcit (5-10 M-% des Bindemittels) allein führte insgesamt zu deutlich geringerer Sulfatbeständigkeit. Hingegen konnten hohe Gehalte an Hüttensand oder Silikastaub auch in Kombination mit Metakaolin und Feinstcalcit den Sulfatwiderstand von Spritzbeton erhöhen. &#13;
The durability of shotcrete can be degraded by chemical attacks, especially if used as ground support in tunnel construction. In the course of the research project "Advanced and Sustainable Sprayed Concrete (ASSpC)" test specimens of dry-mix and wet-mix shotcrete were sprayed in large-scale tests. The sulfate resistance and the leaching behaviour of these shotcretes were assessed in sulfate-bearing solutions. A test procedure based on the use of shotcrete powders shows that hydrated cement phases dissolve in favour of calcite and ettringite neo-formation. The sulfate expansion measured on drill cores in the second procedure corresponds to the behaviour of the powders, especially regarding the reactivity of calcium-and aluminium-bearing hydrated phases. The resistance against thaumasite attack, assessed by measuring the mass loss of prisms, coincides with the former test results. The exclusive use of high-purity metakaolin (7-10 wt-% of binder) or fine calcium carbonate (5-10 wt-% of binder) leads to a decrease in the sulfate durability. However, high amounts of blast furnace slag or silica fume can increase the sulfate resistance of shotcrete even when used in combination with metakaolin or fine calcium carbonate.</abstract>

    <title language="deu">ASSpC – Ein Forschungsprogramm für den Spritzbeton von morgen</title>
    <abstract language="deu">Spritzbeton wird im Tunnelbau als temporäre und permanente Stütz- und Ausbaumaßnahme eingesetzt. Mit der Einführung der alkalifreien Spritzbeton-Technologie wurde um 2004 ein großer Qualitätssprung erzielt. Trotzdem besteht noch Optimierungsbedarf. Alle Bauwerke sollten heute nachhaltig und dauerhaft erstellt werden. Spritzbeton sollte daher aus möglichst umweltneutralen Stoffen hergestellt werden und auch in aggressiver Umgebung dauerhaft, ohne ungünstige Auswirkungen auf das Gesamtbauwerk, seine Aufgaben erfüllen. Das kann nur mit optimierten Rezepturen unter Einsatz ausgewählter Ausgangsstoffe realisiert werden. Das von der FFG in Österreich geförderte Forschungsprogramm „Entwicklung neuer dauerhafter und nachhaltiger Spritzbetone“ (Advanced and Sustainable Sprayed Concrete) setzt genau hier an.</abstract>

    <title language="deu">Instandsetzung Bosruck-Eisenbahntunnel:Entwicklung von Spritzbeton mit erhöhtem Widerstand gegen Thaumasit-Sulfatangriff</title>
    <abstract language="deu">Im Bosruck-Eisenbahntunnel kam es in Folge v on intensivem Sulfatangriff durch Thaumasitbildungen zu erheblichen Betonschäden. Bisher sieht das Regelwerk (ÖNORM B 4710-1 und ÖVBB-RL Spritzbeton) bei Sulfatangriff den Einsatz von C 3A-freien Bindemitteln vor – dies gilt auch für Spritzbeton. Untersuchungen haben gezeigt, dass C 3A-freier Zement keinen wesentlich verbesserten Widerstand gegen den Thaumasit-Sulfatangriff aufweist. Im Zuge der Tunnelinstandsetzung war es das vorrangige Ziel, Spritzbeton mit erhöhtem Widerstand gegen Thaumasit-Sulfatangriff und ausreichender Frühfestigkeit zu entwickeln. In diesem Beitrag werden neu entwickelte Mischungsansätze und deren Umsetzung im Labormaßstab vorgestellt. Die mechanischen Kennwerte dieser Rezeptur (z.B. Frühfestigkeitsentwicklung) sowie die Ergebnisse der Dauerhaftigkeitsuntersuchungen zeigen, dass eine Rezeptur mit optimiertem Bindemittelgehalt die hohen Anforderungen im Tunnel erfüllen kann. Die Erfahrungen aus der praktischen Umsetzung im Zuge der Instandsetzungsarbeiten des Bosruck-Eisenbahntunnels im Jahre 2016 waren positiv.</abstract>

    <title language="spa">Estudio de las reacciones de hidratación temprana en el hormigón proyectado</title>
    <abstract language="spa">El hormigón proyectado es un tipo de hormigón especial utilizado como soporte de rocas durante la construcción de túneles y excavación de minas, entre otras aplicaciones. Las principales características de este tipo de hormigón son el fraguado rápido y el desarrollo de una muy alta resistencia mecánica a edades tempranas, lo cual permite que el hormigón se fije a la base sin necesidad de un soporte extra, endureciéndose en pocos minutos. Las reacciones de hidratación que ocurren en las primeras horas en el hormigón proyectado determinan el desarrollo de las propiedades mecánicas y su estudio es de crucial importancia para entender y optimizar el comportamiento de este tipo de hormigones. El estudio de estas reacciones, sin embargo, resulta relativamente complicado por varias razones: (i) el hormigón proyectado endurece muy rápido, lo cual dificulta su manejo durante los ensayos experimentales, y (ii) composiciones similares mezcladas en el laboratorio no se comportan de forma similar a las proyectadas. En este trabajo se presenta una metodología experimental desarrollada para el estudio de las reacciones de hidratación que ocurren en el hormigón proyectado durante las primeras horas y su correlación con la resistencia mecánica.</abstract>

    <title language="eng">From Lab Scale Spraying to Real Scale Shotcreting and back to the Lab</title>
    <abstract language="eng">Before new mixes are sprayed in real scale applications, lab experiments have to be carried out to provide a basis for predicting a good performance in real scale. In many cases, to understand the correlations between the behavior in the lab and in real scale spraying, a further set of experiments after the real spraying is required. In this paper we present such a two way process for two new wet mixes, one with a very low tricalcium aluminate Portland cement and the other one with a CEM I with addition of ultra-fine calcite. Calorimetry and Shear-Modulus measurements were used in the lab to monitor hydration evolution. In the real scale spraying compressive strength was measured at periodic intervals up to 24 hours. The hydration of the sprayed samples was stopped at 3, 6 and 24 hours and samples were scanned with X-ray for the identification and quantification of the phases present. The results presented are used to discuss the extent to which lab experiments can predict the behavior of mixes in real scale and how small changes in the raw materials and the mixes can lead to quite different results.</abstract>
