Holcim launches Phoenix, 3D-printed bridge19 December 2023, Published under Cement NewsHolcim has launched Phoenix, the first-of-its-kind 3D-printed concrete masonry bridge built using 10t of recycled materials, at its Innovation Hub in Europe. Using its proprietary ECOCycle® circular technology, Holcim developed a custom concrete ink for Phoenix with recycled materials inside. Phoenix demonstrates how circular construction combined with 3D concrete printing can enable low-carbon infrastructure applications. Circular construction, using computational design and 3D print... |
3D printing concrete: motivations, status and outlook11 December 2023, Published under Cement NewsWhile automating concrete construction is not a novel idea, its more recent adoption has been driven by a need for productivity and sustainability. But what is its future? By Timothy Wangler, ETH Zürich Institute for Building Materials, Zurich, Switzerland. Figure 1: 3D printing technology enables considerable material and carbon footprint savings (right) with structures consisting of ribbed slabs, reminiscent of Pier Luigi Nervi’s designs (left) M... |
Assessing the value of concrete and cement as a carbon sink08 December 2023, Published under Cement NewsThis week, the Mineral Products Association (MPA) prepared a 112-page report for the UK Department of Energy Security and Net Zero (DESNZ) to ascertain a two-tier recarbonation model that measures the amount of CO2 absorbed from the atmosphere by concrete in the UK. 'Recarbonation' or carbonation describes how concrete and other cement-containing products naturally absorb and permanently store CO 2 during their lifetime, reversing the calcination reaction. While the Intergovernmental Pan... |

Cement-free mineral foams for 3D printing05 December 2023, Published under Cement NewsETH Zurich has launched a project known as Airlements, which pioneers the use of cement-free mineral foams derived from recycled industrial waste, including fly ash from industrial blastfurnaces, to produce 3D printed building components. Spearheaded by doctoral researcher Patrick Bedarf from Professor Benjamin Dillenburger’s Digital Building Technologies group, the technology promises to reduce heating and cooling costs and to revolutionise the efficiency of construction material usage. ... |
Mission Possible reports says CCUS is falling short05 December 2023, Published under Cement NewsTen of the world’s largest cement and concrete companies, including Heidelberg Materials , CEMEX and Holcim , have joined architects, engineers and construction firms in a collective acknowledgement for action, known as Mission Possible Partnership (MPP). MPP has developed a new strategy with industry input that sets out milestones and commitments needed by government, industry and investors over the next 25 years to make net zero emissions in concrete and cement a reality. The strategy,... |
Swiss team draws on archives to develop low-carbon binders01 December 2023, Published under Cement NewsA team of experts from EPFL (Switzerland), ETH Zurich and a Geneva-based architecture firm has developed a new type of non-reinforced concrete made from stone offcuts. Their method, known as ‘Cyclopean’, draws on ancient technologies uncovered in historical archives to reduce the use of carbon-intensive cement-based binders. In October this year, the team built six load-bearing walls in Lucery-Villars, Switzerland, using recovered stone-quarry waste and fieldstone. The prototype str... |
