Environmental life cycle assessment of coarse natural and recycled aggregates for concrete
Abstract
Purpose: To present a comparative life cycle assessment (LCA) of natural and recycled coarse aggregates used in concrete production. Methods: LCA was used to compare the environmental impacts of three alternative of procurement of coarse aggregates for concrete production: extraction and processing of natural aggregates; recycling of demolished concrete either using a fixed or a mobile plant. Site-specific data supplied by companies were used to model the life cycle of these aggregates. A sensitivity analysis was also made for the critical stages of these three life cycles. Results and conclusion: This paper presents and analyses innovative LCA data of production of coarse aggregates, both natural and recycled (from mobile or fixed recycling plants). The recycling process of aggregates has to be optimised, following a selective demolition of buildings that maximises waste recovery, reuse and recycling. The use of these aggregates in the production of concrete is more favourable than natural aggregates only in terms of land use and respiratory inorganics, but coarse recycled aggregates can present a better environmental performance than natural ones if fine recycled aggregates are also used in concrete production instead of being sent to a landfill. These results are, however, very sensitive to the transportation distances.

Investigating a case of aggregate production near Rome, Simion et al indicate that secondary materials have only 40% of the impact of aggregates from natural resources, but not all uses result in such environmental benefits.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
