Life cycle assessment applied to recycled aggregate

2019-1-1  Amongst the LCA applied to recycled aggregate concrete, the goal definition is based on the differential environmental performance compared to conventional concrete mixtures under different scenario constraints (replacement ratio, coarse/fine substitutions and type of aggregate, etc.).

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.

Comparative LCA of concrete with recycled

2020-8-6  Life cycle assessment (LCA) methodology is applied using Simapro© software. A cradle to grave analysis is carried out. The results are analysed based on the database Ecoinvent 3.3 and Impact 2002+. Results show that the concrete with 25% recycled aggregates is the best solution from an environmental point of view.
