Life cycle assessment of concrete structures with reuse

Life cycle assessment of concrete structures with reuse ...

In the construction industry, reuse and recycling strategies help reducing waste, saving energy and cutting down emissions by converting construction and demolition (CD) waste into resources. This study proposes a novel framework to guide the life cycle assessment (LCA) of concrete structures with reuse and recycling strategies.
