Project Aim
The overarching aim is to build new knowledge and develop technologies for:
- smart recovery of construction resources from hard-rock materials excavated during tunnelling.
- on-site use of the recovered materials as aggregates or fillers for low-carbon sustainable concrete. Enabling minimize waste generation, material transport and environmental footprint.
Development Objectives
Objective 1: Development of sensor-based, inline characterization technology to steer extraction and processing of excavated materials towards high-quality resources to be used in high-grade constructions applications.
Objective 2: Development of low-clinker cements with a high level of mineral additions (clinker replacement materials) recovered from mechanochemically and thermally treated excavation fines
Objective 3: Next generation low-carbon & circular concrete comprising recovered and recycled aggregates:
- Development of predictive models linking ET aggregate/cement/filler properties (including statistical dispersity) with concrete performance.
- Design and prototype testing of structural concrete elements (e.g. liners) using ET excavated materials: feedback procedures (envelope/limits/acceptance criteria) regarding suitable ET concrete materials .
- Development and testing of an integrated sensor early warning concept for tunnel liners and tunnel sections to assess structural integrity and durability.
