Materials usually show anomalous behaviors at ultra-low temperatures. Cryogenic concrete withstands prolonged exposure to temperatures as low as −165 °C and endures repeated ultra-low temperature freezing-thawing cycles. However, such cryogenic environments pose significant challenges to the safety and durability of cement concrete. This book presents an exploration to uncover the secrets of micro/nanostructures and properties of cement concrete under cryogenic attack. Across concise chapters, it introduces the fundamental concepts of cryogenic concrete and calcium-silicate-hydrate (C-S-H), followed by an in-depth examination of pore stability, degradation pathways, and molecular-editing strategies for C-S-H. Additionally, it addresses nanomechanical behavior and frost damage from an atomistic perspective, delivering a complete picture of cryogenic concrete.

Since the Second World War the demand of energy has undergone an exponential growth that has led to a sharp annual increase in the use of natural gas in both, cities and thermal power stations. Nowadays, the strategic relevance of natural gas as a main source of energy is evident with a contribution of more than 20% of the total world consumption. This development in increasing demand of natural gas has led for a need of suitable storage and transportation infrastructure. Various gases, especially hydrocarbons, are preferably stored in liquid form for transportation and storage since the phase transformation from gas to liquid comes with a significant reduction of the volume (e.g. up to 600 times). Gases can be liquefied by raising the pressure or by cooling to their boiling point, which for most gases is below 0°C. This is known as cryogenic storage. The term cryogenic is derived from two Greek words, namely kryos meaning icy-cold and genes which can be translated as shape. These fib recommendations are concerned about post-tensioning systems used in cryogenic tanks and have been formulated on the basis of actual available knowledge with the aim to reflect the current state of the art. Consequently, these recommendations have included a classification of the different cryogenic tanks typologies used in the past and nowadays, the associated different tendon types depending on their exposure to low temperature (e.g. never, only accidentally or during normal tank operation) and the testing regime required for acceptance of the materials and the post-tensioning system according to this document. An international working group comprising more than 20 experts from administrative authorities, universities, laboratories, owners, structural designers, suppliers of prestressing steels and post-tensioning systems suppliers have actively contributed in order to develop these recommendations. This text has been written to cover best construction practices around the world, and to provide material specifications which are considered to be the most advanced available at the time of preparing this text. For ease of use (for Owner, Designer and Post-tensioning System Supplier), the content has been arranged systematically according to the system components into chapters focusing on performance characteristics, requirements and acceptance criteria.

The International Federation for Structural Concrete (fib) is a pre-normative organization. 'Pre-normative' implies pioneering work in codification. This work has now been realized with the fib Model Code 2010. The objectives of the fib Model Code 2010 are to serve as a basis for future codes for concrete structures, and present new developments with regard to concrete structures, structural materials and new ideas in order to achieve optimum behaviour. The fib Model Code 2010 is now the most comprehensive code on concrete structures, including their complete life cycle: conceptual design, dimensioning, construction, conservation and dismantlement. It is expected to become an important document for both national and international code committees, practitioners and researchers. The fib Model Code 2010 was produced during the last ten years through an exceptional effort by Joost Walraven (Convener; Delft University of Technology, The Netherlands), Agnieszka Bigaj-van Vliet (Technical Secretary; TNO Built Environment and Geosciences, The Netherlands) as well as experts out of 44 countries from five continents.

Materials and Structures in Cold Regions: The Impact of Low Temperatures on Construction Materials and the Structural Behaviour of Structural Members is based on the latest research undertaken at Tianjin University, P.R. China and National University of Singapore. The book provides detailed experimental research on the influences of low temperatures on the mechanical properties of constructional materials and structural behavior of typical structural members at low temperatures, e.g., beams, columns, and walls. The theoretical and numerical models in the book on structural members at low temperatures simplifies and provides guidelines for structural engineers working on cold-region projects.The book blends the fundamental development of concepts with the practical specification of materials and structures at low temperatures. - Provides detailed experimental research on the influence of low temperatures on the mechanical properties of constructional materials, and structural behavior of typical structural members at low temperatures, e.g., beams, columns, and walls - Covers fundamental development of concepts, with the practical specification of materials and structures at low temperatures - Presents the latest research, undertaken at Tianjin University, P.R.

The objectives of MC2010 are to (a) serve as a basis for future codes for concrete structures, and (b) present new developments with regard to concrete structures, structural materials and new ideas in order to achieve optimum behaviour. MC2010 includes the whole life cycle of a concrete structure, from design and construction to conservation (assessment, maintenance, strengthening) and dismantlement, in one code for buildings, bridges and other civil engineering structures. Design is largely based on performance requirements. The chapter on materials is extended with new types of concrete and reinforcement (such as fibres and non-metallic reinforcements). The fib Model Code 2010 also gives corresponding explanations in a separate column of the document. Additionally, MC2010 is supported by background documents that have already been (or will soon be) published in fib bulletins and journal articles. MC2010 is now the most comprehensive code on concrete structures, including their complete life cycle: conceptual design, dimensioning, construction, conservation and dismantlement.
