CONCRETE PIPES AND MANHOLESwww.cpi-worldwide.com CPI %u2013 Concrete Plant International %u2013 5 | 2025 115SummaryOur built infrastructure, such as the pipe system made of concrete and reinforced-concrete pipes, is a source of raw materials. The pilot project with the Federal Association of Concrete Sewer Systems (FBS) and the R%u00f6ser Group has shown that 100% recycling of concrete rubble is feasible from a production and concrete technology perspective. An important finding was that the quality of raw material processing is crucial for the sustainability of the new concrete. The reCO2ver process enabled 100% reuse of old concrete: a) The cleaned sand and gravel were of almost primary quality and could be used without problems. b) The resulting cement powder could be used as a cement substitute.Concrete technology insights, such as the precise determination of material properties and volumetric analysis of the concrete, help with optimization.Sika supports the concrete circular economy with the reCO2ver process. The provision of the patented process in combination with specialized application technology leads to the safe implementation of this innovative technology. nFURTHER INFORMATIONSika Deutschland CH AG & Co KGKornwestheimer Str. 103-10770439 Stuttgart, GermanyT +49 711 8009 0 info@de.sika.com, www.sika.dewww.sika.com/en/knowledge-hub/reco2ver-concrete-recycling.htmlBundesfachverband Betonkanalsysteme e.V.www.fbs-beton.de/recyclingR%u00f6ser Vertriebs GmbHwww.roeser-gmbh.de/de/produkte/k-reco2verwww.prinzing-pfeiffer.comAchieve unparalleled results with cutting-edge radial press technology designed for the most demanding concrete pipe production needs.Whether for reinforced or non-reinforced concrete pipes, according to internationalstandards, the Radial Press is your partner in delivering durable, high-quality solutions %u2013 every time.Leading with Innovation, inspired by Traditionsince 1862Short Cycle Times /High Production OutputFast Mold ChangeHighest Reliabilitywith low WearPrecisionin every Turn The Radial PRess RP by Prinzing PFeiFFer Downloadbrochures
