Sustainability assessment of maintenance based on concrete - a systematic review

摘要

This article explores and synthesizes relevant methods, issues, and findings of sustainability assessments applied to the maintenance and repair methods using concrete and cement-based materials. Our research questions are, firstly, which pillars of sustainability are addressed and which indicators are currently applied, and secondly, what possibilities exist to create an overall result for the assessment. We use a systematic literature review to summarize the knowledge and stimulate discussion on further methodological development in this field. Our review shows that sustainability assessment is applied with different levels of detail, quality, and methodological choices. Among environmental impacts, global warming is most frequently mentioned. Economic impacts are dominated by external costs that are often linked to social impacts. In general, the most critical issue is the long-term orientation of the planning of structures and measures.
