This book is mainly based on the results of the EU-funded UE-FP7 Project EnCoRe, which aimed to characterize the key physical and mechanical properties of a novel class of advanced cement-based materials incorporating recycled powders and aggregates and/or natural ingredients in order to allow partial or even total replacement of conventional constituents. More specifically, the project objectives were to predict the physical and mechanical performance of concrete with recycled aggregates; to understand the potential contribution of recycled fibers as a dispersed reinforcement in concrete matrices; and to demonstrate the feasibility and possible applications of natural fibers as a reinforcement in cementitious composites. All of these aspects are fully covered in the book. The opening chapters explain the material concept and design and discuss the experimental characterization of the physical, chemical, and mechanical properties of the recycled raw constituents, as well as of the cementitious composite incorporating them. The numerical models with potentialities for describing the behavior at material and structural level of constructions systems made by these composites are presented. Finally, engineering applications and guidelines for production and design are proposed.

This book gathers peer-reviewed contributions presented at the 3rd RILEM Spring Convention and Conference, held at Guimaraes and hosted by the University of Minho, Portugal, on March 9-14, 2020. The theme of the Conference was "Ambitioning a Sustainable Future for Built Environment: comprehensive strategies for unprecedented challenges", which was aimed at discussing current challenges and impacts of the built environment on sustainability. The present volume is dedicated to the topic "Strategies for a resilient built environment", which covers the current and emerging approaches that lead to an optimized design and maintenance of constructions and systems. It includes the development of service life models and life cycle design, in order to maximise longevity and level of service while minimising the environmental impact of constructions and systems. It also includes the analysis and design of larger systems, such as communities, cities or regions, aiming at reducing risk and increasing resilience. The following subtopics are included: resilience and robustness of the built environment and communities at local and global scales; risk based inspection and maintenance; life cycle analysis and service models; performance based design; improved design strategies by integrating materials and structures.
