Compared Environmental Impact Analysis of Alfa and Polypropylene Fibre-Reinforced Concrete
Résumé
This study was conducted in order to examine the environmental and the mechanical properties of two fibre-reinforced concretes, namely Alfa fibres and polypropylene fibres. In this study, the life cycle assessment (LCA) method was used, since this process is likely to quantify the environmental impacts of concrete or concrete production industry. The environmental analyses showed that alfa fibres generate fewer impacts than polypropylene fibres. The results revealed that the use of the Alfa fibres reinforced concretes is efficient solution for climate change mitigation, for the reason that they generate: (1) a less fossil fuel depletion; (2) produce lower emissions of greenhouse gases; (3) develop a lesser atmospheric emission of particles, (4) reduce the marine ecotoxicity; and (5) participate in decreasing the photochemical oxydation.
