Developments in (infralightweight) concrete construction
Do we need to reinvent concrete? Perhaps not. But we do need to develop and improve it continuously, without forgetting the hard-won lessons of the past. A few contributions to this development are outlined in this talk.
Houses made from infralightweight concrete could contribute to climate resilience and futureproofing, as part of a renewed focus on simple, sound and robust construction. Along the way, there have been – and still are – challenges, particularly with site workmanship and quality assurance. This year, the first prefabricated infralightweight concrete elements will be erected, hopefully solving most of these issues.
In structural design, we are also pursuing other material innovations: timber composite systems, prestressed carbon-reinforced concrete, lightweight exposed concrete precast floor units such as Concap, CO₂-reduced concrete, the impacts of carbon capture and storage (CCS), as well as the upkeep of existing structures and the potential reuse of concrete components.
Our work takes place under the combined pressures of regulatory frameworks, economic incentives, and continuously refined verification methods. Some examples will illustrate how these pressures shape our efforts to improve concrete.
