New tectonics of concrete through rubble reuse

Corentin Jean Dominique Fivet, Stefana Parascho, Maxence Grangeot

Driven by the sustainability of the construction industry, concrete rubble is increasingly considered as a construction material rather than a waste. Analysing structures from such material through the conceptual tool of tectonics highlights a fertile grou ...

Large Concrete Rubble as a New Structural Construction Material: Opportunities and Digital Processes for Load-Bearing Walls

Christophe Moser, Corentin Jean Dominique Fivet, Maléna Bastien Masse, Maxence Grangeot

Concrete is amongst the most wasted materials on earth, mainly due to building demolitions. Currently, after a building’s end of life, concrete is crushed to be used as replacement gravel in new concrete mixes or for backfilling. Aiming to increase the cir ...

Disused Concrete, Digital Acupuncture and Reuse

Corentin Jean Dominique Fivet, Maléna Bastien Masse, Stefana Parascho, Maxence Grangeot

Crushing concrete liberated from demolished buildings to provide recycled aggregate is argued to be a sustainable way of reducing material extraction. Yet, in these high‐energy processes, large amounts of new cement is often used, negating this as a low‐ca ...

Concrete rubble as a new construction material: Panorama of applications to known structural typologies

Corentin Jean Dominique Fivet, Stefana Parascho, Maxence Grangeot

Concrete rubble is among the most wasted materials worldwide. In this paper, we present a panorama of the upcycling potential of disused concrete rubble as construction material for new low-carbon structures. We identify 15 existing structural applications ...

Upcycling concrete rubble into masonry walls: Design and assessment of two prototypes built with digitally augmented tools

Corentin Jean Dominique Fivet, Maléna Bastien Masse, Stefana Parascho, Maxence Grangeot

Concrete rubble is currently a downcycled material whose upcycling remains under-explored and complex. This paper presents an accessible upcycling strategy to design and build slender structural masonry walls made from off-the-pile large demolition concret ...

An Investigation into Machine Learning Matchmaking for Reused Rubble Concrete Masonry Units (RR-CMU)

Maxence Grangeot

This paper attempts to situate concrete recycling within the contemporary economically convenient waste streams. In the case of concrete, the economically convenient waste stream is to demolish it into rubble and take it to landfill or grind it into aggreg ...

From soon-to-be demolished mushroom column slabs to reused reinforced concrete saw-cut assemblies: the case of the rebuiLT pavilion

Corentin Jean Dominique Fivet, Maléna Bastien Masse, Célia Marine Küpfer, Maxence Grangeot

The piecewise reuse of soon-to-be-demolished cast-in-place reinforced concrete (RC) structures in new structural projects poses new design challenges. Unlike the disassembly of prefabricated structures guided by existing connections, deconstructing monolit ...

Reading the existing: What discarded materials bring to the project

Corentin Jean Dominique Fivet, Célia Marine Küpfer, Maxence Grangeot, Barbara Ludivine Justine Lambec

Buildings are being demolished sooner and sooner after their construction. Regrettably this trend shows no signs of being reversed anytime soon. Demolition activities are driven today by real estate developments fueled by investment logics and rapidly chan ...

Rising from rubble - Leveraging existing construction tools for upcycling concrete waste into slender walls

Katrin Beyer, Corentin Jean Dominique Fivet, Stefana Parascho, Qianqing Wang, Maxence Grangeot

In this paper, we present a new method for upcycling concrete rubble waste into slender walls through the lightweight digital augmentation of mainstream construction machines. By using such method, the environmental impact of concrete construction and demo ...

Structural Concrete Rubble Arrangements - A Framework for Upcycling Demolition Waste into Slender Masonry Walls for Buildings

Katrin Beyer, Corentin Jean Dominique Fivet, Stefana Parascho, Qianqing Wang, Maxence Grangeot

Reused concrete rubble is a challenging material to design and construct with despite its potential for diverging waste from landfilling and energyintensive recycling. We propose a design to construction framework that leverages a camera and computationall ...
