Precast CSA-based concrete tunnel lining segments reinforced with GFRP bars: Challenges and opportunities
https://orcid.org/0000-0001-6480-4399
Abstract This research study investigates the potential of using Calcium Sulfoaluminate (CSA) binder as a sustainable alternative to ordinary Portland cement (OPC) in the production of precast concrete tunnel lining (PCTL) segments. The effectiveness of CSA-based concrete, reinforced with Glass Fiber-Reinforced Polymer (GFRP) bars, was examined through an experimental program. Comparative analyses, including analytical, experimental, and Life Cycle Assessment (LCA) comparisons, were conducted with OPC-based segments reinforced with traditional steel. The results indicate that the proposed CSA/GFRP solution has the potential to improve sustainability in mechanized tunnelling and prefabrication. A case study is also presented to support these findings.
Highlights Eco-sustainable process for mechanized tunnel lining construction. Calcium Sulfoaluminate binder and GFRP bars in the production of tunnel segments. Full-scale performances of CSA cement-based precast segments with GFRP bars. LCA and carbon footprint comparison of OPC/steel and CSA/GFRP tunnel segments. Case study with theoretical prediction of the construction phases.
