This book gathers the peer-reviewed contributions presented at two parallel, closely interconnected events on advanced construction materials and processes, namely the 2nd International RILEM Conference on Rheology and Processing of Construction Materials (RheoCon2) and the 9th International RILEM Symposium on Self-Compacting Concrete (SCC9), held in Dresden, Germany on 8-11 September 2019. The papers discuss various aspects of research on the development, testing, and applications of cement-based and other building materials together with their specific rheological properties. Furthermore, the papers cover the latest findings in the fast-growing field of self-compacting concrete, addressing topics including components’ properties and characterization; chemical admixtures, effect of binders (incl. geopolymers, calcined clay, etc.) and mixture design; laboratory and in-situ rheological testing; constitutive models and flow modelling; numerical simulations; mixing, processing and casting processes; and additive manufacturing / 3D-printing. Also presenting case studies, the book is of interest to researchers, graduate students, and industry specialists, such as material suppliers, consultants and construction experts.

This volume highlights the latest advances, innovations, and applications in the field of fiber-reinforced concrete (FRC) and textile-reinforced concrete (TRC), as presented by scientists and engineers at the RILEM-fib XI International Symposium on Fiber Reinforced Concrete (BEFIB), held in Dresden, Germany, on September 15-18, 2024. It discusses a diverse range of topics concerning FRC and TRC, including technological aspects, mechanical properties, long-term performance, analytical and numerical models, structural design, codes and standards, as well as practical applications and case studies.

This open access book presents the collective research outcomes of the German Research Foundation (DFG) funded Priority Program (SPP 2005): Opus Fluidum Futurum—Rheology of reactive, multiscale, multiphase construction materials, a multidisciplinary initiative to advance the science of rheology-based sustainable construction processes. This book delivers comprehensive insights into: (a) Interactions of reactive particles, with a focus on how particles of various reactivity, sizes, and shapes engage in physical and chemical interactions. (b) Deformation behavior of fresh concrete with new insights into the rheological assessment of cementitious mixes containing large aggregates and fibers. (c) Concrete transport and processing, examining how concrete flows during pumping, filling formwork, and placement using advanced techniques such as 3D printing. All insights are supported by carefully designed experiments and simulations spanning meso- to macro-scales, laying the groundwork for innovative materials and processes that address the evolving needs of modern construction.

This is the state-of-the-art report prepared by the RILEM TC “Application of Super Absorbent Polymers (SAP) in concrete construction”. It gives a comprehensive overview of the properties of SAP, specific water absorption and desorption behaviour of SAP in fresh and hardening concrete, effects of the SAP addition on rheological properties of fresh concrete, changes of cement paste microstructure and mechanical properties of concrete. Furthermore, the key advantages of using SAP are described in detail: the ability of this material to act as an internal curing agent to mitigate autogenous shrinkage of high-performance concrete, the possibility to use SAP as an alternative to air-entrainment agents in order to increase the frost resistance of concrete, and finally, the benefit of steering the rheology of fresh cement-based materials. The final chapter describes the first existing and numerous prospective applications for this new concrete additive.
