Reuse of Existing Reinforced Concrete Elements ‐ Automated Fine Processing, Connection Designs, and Quality Assurance

The construction sector faces major challenges in terms of resource efficiency and environmental impact. To address the lack of sustainability in infrastructural development, this paper proposes an innovative concept for the reuse of aged reinforced concrete elements. The aim is to enable the selective reconditioning, segmentation and reintegration of concrete components into new structures through an automated production system. The system combines advanced automation technologies with suitable connection designs and comprehensive quality assurance methods to ensure structural integrity and long‐term performance. By applying a cradle to cradle philosophy and establishing a closed‐loop supply chain for concrete elements, the approach significantly reduces waste, conserves natural resources, and lowers CO 2 emissions. Building on this foundation, the paper reviews the state of the art in fine processing of aged concrete elements, with a focus on connection designs, automated processing, and quality assurance as key enablers of sustainable manufacturing and resilient infrastructure.
