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.

Adopts a holistic approach to material and structural design of advanced cementitious composites with recycled and natural constituents Explains how to employ the composites in engineering practice Presents guidelines for production and structural design Includes supplementary material: sn.pub/extras

Enzo Martinelli is Associate Professor of Structural Analysis and Design at the Department of Civil Engineering of the University of Salerno, Italy. In 2003 he completed his PhD in Structural Engineering with a Thesis on the numerical simulation of the structural response of steel-concrete composite beams in partial interaction. In the last fifteen years he has been working on various subjects of relevance in civil and structural engineering, such as the experimental characterisation and theoretical modelling of concrete structures, the seismic response of structure, with emphasis on retrofitting of existing ones, the mechanics of fiber-reinforced composite materials and their use in strengthening existing concrete and masonry members and structures. More recently, he has been Principal Coordinator Contact in the EU-funded projects Environmentally-friendly solutions for Concrete with Recycled and natural components (EnCoRe, FP7-PEOPLE-2011-IRSES n. 295283), granted as part of the 7th Framework Programme, and SUstainability-driven international/intersectoral Partnership for Education and Research on modelling next generation CONCRETE (SUPERCONCRETE, H2020-MSCA-RISE-2014 n. 645704), financed within the framework of Horizon 2020.
