Upcycling Space Structures (Preface to special issue)

Corentin Jean Dominique Fivet, Olivier Baverel

The construction industry’s contribution to the deterioration of Earth’s ecosystem is huge. 11% of all anthropic greenhouse gas emissions worldwide are due to the construction, demolition, and transformation of buildings and infrastructure. Construction an ...

This paper investigates the phenomenon of cover spalling in reinforced concrete induced by bond or by the action of an inner pressure. This research is based on an experimental programme comprising a series of bond tests and a series of tests with inner-pr ...

2021

The behavior of reinforced-concrete structural elements under moving loads involves many complex parameters related to material properties, vehicle loading, environmental changes and structural response. It is difficult to generate the real conditions of l ...

Taylor & Francis2021

The reduction of green-house gas emissions is one of the global challenges that our society is facing and the production of cement plays a major role because concrete is the most used material worldwide. For every 1000 kg of cement produced, 900 kg of CO2, ...

Environmental impacts and decarbonization strategies in the cement and concrete industries

Karen Scrivener, Aurélie Rosine Favier

The use of cement and concrete, among the most widely used man-made materials, is under scrutiny. Owing to their large-scale use, production of cement and concrete results in substantial emission of greenhouse gases and places strain on the availability of ...

Concrete compressive strength: From material characterization to a structural value

Aurelio Muttoni, Qianhui Yu, Miguel Fernández Ruiz, Francesco Rafael Alberto Moccia

The compressive resistance of concrete in new structures is usually characterized on the basis of tests performed on concrete cylinders or cubes under relatively rapid loading conditions. Although efficient for material characterization, these tests do not ...

Optimum design of frame structures from a stock of reclaimed elements

Corentin Jean Dominique Fivet, Gennaro Senatore, Jan Friedrich Georg Brütting

This paper presents optimization methods to design frame structures from a stock of existing elements. These methods are relevant when reusing structural elements over multiple service lives. Reuse has the potential to reduce the environmental impact of bu ...

Life Cycle Analysis of Strengthening Existing RC Structures with R-PE-UHPFRC

Emmanuel Denarié, Guillaume Habert, Amir Hajiesmaeili

(PE)-UHPFRC, a novel strain hardening ultra high-performance fiber reinforced concrete (UHPFRC) with low clinker content, using Ultra-High MolecularWeight Polyethylene (UHMW-PE) fibers, was developed for structural applications of rehabilitation. A compreh ...

Concrete buildings in French-speaking Switzerland, the predominance of frame structures

Salvatore Aprea

This contribution gives an account of how concrete construction developed in French-speaking Switzerland since the end of the nineteenth century. The narrative is based on original sources from the Archives de la construction moderne (Acm) and on data and ...

Waste Reduction Strategies: A Different Perspective on Waste Flow Modeling and its Application to Concrete and Phosphorus

Anna Minata Cissé

Changing consumption patterns and global population growth lead to ever-increasing waste generation. Human activity and waste generation are irrevocably linked, and the current situation thus calls for a more circular approach to waste management, where wa ...
