Disrupting Concrete Construction: digital, sustainable and circular

ETH / Prof. Dr. Philippe Block

Concrete does not want to be a beam, it wants to be an arch. Reintroducing arched geometry for the artificial stone, concrete, significantly reduces the amount of material needed, but also to build with lesser emitting materials. Recent developments in computational design and engineering and construction-scale digital fabrication now allow the introduction of concrete as an extremely sustainable solution for spanning structures such as floor “slabs” or footbridges. This talk will introduce how we can disrupt concrete construction: lightweight, low embodied emissions, using construction demolition waste, fire resistant, providing thermal mass, acoustically performant, dry-assembled prefab, so easily demountable and reusable or entirely and easily recyclable at the end of its life, available at scale and globally, and economically competitive. Sounds too good to be true?
