Computational Modelling of Concrete and Concrete Structures contains the contributions to the EURO-C 2022 conference (Vienna, Austria, 23-26 May 2022). The papers review and discuss research advancements and assess the applicability and robustness of methods and models for the analysis and design of concrete, fibre-reinforced and prestressed concrete structures, as well as masonry structures. Recent developments include methods of machine learning, novel discretisation methods, probabilistic models, and consideration of a growing number of micro-structural aspects in multi-scale and multi-physics settings. In addition, trends towards the material scale with new fibres and 3D printable concretes, and life-cycle oriented models for ageing and durability of existing and new concrete infrastructure are clearly visible. Overall computational robustness of numerical predictions and mathematical rigour have further increased, accompanied by careful model validation based on respective experimental programmes. The book will serve as an important reference for both academics and professionals, stimulating new research directions in the field of computational modelling of concrete and its application to the analysis of concrete structures. EURO-C 2022 is the eighth edition of the EURO-C conference series after Innsbruck 1994, Bad Gastein 1998, St. Johann im Pongau 2003, Mayrhofen 2006, Schladming 2010, St. Anton am Arlberg 2014, and Bad Hofgastein 2018. The overarching focus of the conferences is on computational methods and numerical models for the analysis of concrete and concrete structures.

Sustainable construction, with the overarching goal of reducing the environmental footprint of everything we build is becoming increasingly important and urgent in the light of the climate change the world is facing. The use of innovative and sustainable building materials, especially concrete as the worldwide most commonly used building material, offers a great opportunity to significantly reduce climate-relevant emissions in the construction sector. Due to their performance and reliable durability, the use of innovative high-performance concretes will help to reduce the need for new constructions and to sustainably repair existing infrastructure. In new buildings in particular, the use of high-performance materials can help to save energy and natural resources, which reduces climate-relevant emissions and thus global warming. With the current HiPerMat 6, we are responding to the growing understanding of the impact of our construction activities on the environment by placing greater emphasis on sustainability issues.

Innovative Bridge Structures Based on Ultra-High Performance Concrete (UHPC): Theory, Experiments and Applications introduces more than a dozen innovative bridge structures and engineering applications developed by the author's team based on UHPC. As the new bridge structure developed by UHPC can make outstanding contributions to the realization of the "carbon peaking and carbon neutrality goals" and "sustainable development," and since recent studies have shown that the application of UHPC is expected to greatly reduce the amount of materials and carbon emissions and prolong the life of the structure, this book is an ideal update on the topic. For example, after calculation, when UHPC is applied to the arch bridge with compression as the main stress characteristic, compared with the steel arch bridge, the dead weight of the UHPC arch bridge is basically the same, and the cost and carbon emission are only 34% and 20% of the latter. Ultra-high performance concrete (UHPC) as a new generation of civil structural materials has the characteristics of high strength, high toughness and high durability. Through the collaborative innovation of new materials and new structures, the application of UHPC in bridge engineering is expected to achieve the goal of economical, environmentally-friendly, durable and high performance of the main structure. Teachers readers about the new structures and technologies in bridge engineering developed by the author's team based on UHPC Provides relevant experimental studies and the mechanical properties of different UHPC structures Helps users understand the design method and calculation theory of UHPC bridge structures Covers the characteristics and advantages of new UHPC structures and technologies applied to engineering

Selected chapters from the German concrete yearbook are now being published in the new English "Beton-Kalender Series" for the benefit of an international audience. Since it was founded in 1906, the Ernst & Sohn "Beton-Kalender" has been supporting developments in reinforced and prestressed concrete. The aim was to publish a yearbook to reflect progress in "ferro-concrete" structures until - as the book's first editor, Fritz von Emperger (1862-1942), expressed it - the "tempestuous development" in this form of construction came to an end. However, the "Beton-Kalender" quickly became the chosen work of reference for civil and structural engineers, and apart from the years 1945-1950 has been published annually ever since. Ultra high performance concrete (UHPC) is a milestone in concrete technology and application. It permits the construction of both more slender and more durable concrete structures with a prolonged service life and thus improved sustainability. This book is a comprehensive overview of UHPC - from the principles behind its production and its mechanical properties to design and detailing aspects. The focus is on the material behaviour of steel fibre-reinforced UHPC. Numerical modelling and detailing of the connections with reinforced concrete elements are featured as well. Numerous examples worldwide - bridges, columns, façades and roofs - are the basis for additional explanations about the benefits of UHPC and how it helps to realise several architectural requirements. The authors are extensively involved in the testing, design, construction and monitoring of UHPC structures. What they provide here is therefore a unique synopsis of the state of the art with a view to practical applications.

Ultra-high performance concrete (UHPC) is an advanced cement-based composite material with compressive strength of over 120 MPa, high toughness, and superior durability. Since its development in the early 1990s, UHPC has attracted great interest worldwide due to its advantages. This book covers material selection and mixture design methods for developing UHPC, as well as the performance of UHPC, including fresh and hardened properties, setting and hardening, dimensional stability, static and dynamic properties, durability, long-term properties, and self-healing properties. A range of potential applications and case studies are presented to illustrate how UHPC meets requirements for lightweight, high-rise, large-span, heavy-load bearing, fast-construction, and highly durable structures in civil and construction engineering. Also introduced is a typical new concrete, seawater sea-sand UHPC, which avoids the use of freshwater and river sand in marine construction. The first book to fully cover the design, performance, and applications of UHPC, this is ideal for concrete technologists, designers, contractors, and researchers.

This book addresses corrosion problems and their solutions at facilities in the oil refining and petrochemical industry, including cooling water and boiler feed water units. Further, it describes and analyzes corrosion control actions, corrosion monitoring, and corrosion management. Corrosion problems are a perennial issue in the oil refining and petrochemical industry, as they lead to a deterioration of the functional properties of metallic equipment and harm the environment – both of which need to be protected for the sake of current and future generations. Accordingly, this book examines and analyzes typical and atypical corrosion failure cases and their prevention at refineries and petrochemical facilities, including problems with: pipelines, tanks, furnaces, distillation columns, absorbers, heat exchangers, and pumps. In addition, it describes naphthenic acid corrosion, stress corrosion cracking, hydrogen damages, sulfidic corrosion, microbiologically induced corrosion, erosion-corrosion, and corrosion fatigue occurring at refinery units. At last, fouling, corrosion and cleaning are discussed in this book.

Ultra High Performance Concrete (UHPC) is characterized by a very high compressive strength which may reach more than 200 MPa. The behavior of this material under tension and compression actions has been established to be very brittle in nature. Discontinuous fibers (normally steel fibers) are usually added to the UHPC mix to introduce ductility. In order to investigate the beneficial effects of using fiber reinforced UHPC in structural members subjected to torsion, a series of experimental tests on 17 UHPC beams subjected to pure torsion were carried out. The test beams consisted of plain UHPC beams, UHPC beams reinforced with steel fibers only, UHPC reinforced with steel fibers and different combinations of traditional longitudinal and transverse reinforcement. The plain UHPC beams showed very brittle behavior, whereas the UHPC beams with steel fibers only showed a post cracking ductile behavior. The addition of little steel fiber volume (e.g. 0.5 %) to the plain UHPC beams enhanced the ductility. The enhancement at the ultimate capacity amounts to about 20 %. Meanwhile, the steel fibers with 0.9 % by volume showed much enhanced ductility and a maximum enhancement of the torsional carrying capacity up to 32 %. The addition of moderate steel fiber volume (e.g. 0.9 %) to one type of traditional reinforcement (either longitudinal or transverse) accomplished an effective post cracking torsional carrying mechanism. The steel fibers shows a tendency to replace the missing type of traditional reinforcement, however this should be confirmed by more tests and by using higher steel fiber volumes. A series of experimental tests on fiber reinforced UHPC prisms to investigate the post cracking shear strength and stiffness of the used UHPC mix (e.g. M3Q) was conducted. The results of these tests revealed that this fine grained UHPC mix has a weak post cracking shear behavior. The results of these tests were used later in the Finite Element (F.E) model. An analytical model based on the well known thin-walled tube analogy was developed in order to estimate the torsional carrying capacity of beams under pure torsion having different combinations of steel fibers and traditional reinforcement. The comparison between the test and model results showed very good agreement for all cases. A finite element model based on calibrated small scale tests was developed using ATENA F.E. package to predict the full load-deformation behavior of the test beams. The predictions of the model show very good agreement with the test results.

This study therefore investigated and improved cementitious properties of pozzolan blended with calcium hydroxide, gypsum and cement in order to extend its use from low strength mortars to concrete works which can be used for low to medium rise structural applications. Characterization, strength tests and durability tests were performed on pozzolan mixtures under laboratory conditions and the effects of adding gypsum to pozzolan and calcium hydroxide mixtures on the compressive strength and durability of cured concrete specimens were investigated.
