Smart casting of concrete structures by active rheology and stiffening control (ERC advanced grant project)

Boekbijdrage - Boekabstract Conferentiebijdrage

Concrete production processes do not take fiill advantage of the rheological potential offfesh cementitious materials, and are still largely labour-driven and sensitive to the humanfactor. The recently started ERC Advanced Grant project 'SmartCast' proposes a new concretecasting concept to transform the concrete industry into a higlily automated technologicalindustry. Currently, the rheological properties of the concrete are defined by mix design andmixing procedure without any further active adjustment during casting. The goal of the'SmartCast' project is the active control of concrete rheology during casting, and the activetriggering of early stiffening of the concrete as soon as it is put in place. The ground-breakingidea to achieve this goal, is to develop concrete with actively controllable rheology by addingadmixtures responsive to extemally activated electromagnetic frequencies. Inter-disciplinaryinsights are important to achieve these goals, including inputs from concrete technology,polymer Science, electrochemistry, rheology and computational fluid dynamics. In the shortterm, achieving the active control of the pumping slip layer will have an immediate impact onconcrete industry, as this can be applied on pump trucks without interfering with the clementsto be cast. In the longer term, making possible concrete casting with active control of flowand stiffening will be a totally new paradigm for concrete industry. Moving from U+2018passivelyU+2019relying on evolving properties of ffesh concrete, to U+2018activelyU+2019 controlling rheology andstiffening will revolutionize concrete industry and bring quality levels to higher standards.The developed active rheology control will also provide a fundamental basis for thedevelopment of future-proof 3D printing techniques in concrete industry. For society, it willmean more reliable construction, with less damage cases and less failures, while betterpreserving the environment (reduced carbon footprint, reduced noise and vibration levels,reduced exposure of technicians to safety and health risks).
