Environmental evaluation of applications of concrete with recycled material from tyre
Alternatives for using end-of-life tyres as a component of concrete are currently being studied. Particularly, granulated rubber and steel fibres from tyres can generate relevant technical benefits in concrete. However, it is not clear what environmental benefits these alternatives can provide. Hence, a study was carried out to evaluate, from an environmental perspective, applications of concrete with recycled materials from tyres. For this purpose, a streamlined life cycle assessment was developed to compare the impact of the use of concrete with tyre materials and traditional concrete for safety barriers, railway sleepers, pavements and masonry mortar. Furthermore, the analysis was based on energy-thermal simulations, experimental work and collected studies. The results indicated that the safety barrier and railway sleeper with tyres can reduce the harmful impact by 60% and 50%, respectively. For masonry mortar and concrete pavement applications, the impact reduction was between 4% and 10%. Moreover, one case was observed where, to comply with the technical requirements, it was necessary to incorporate more material into the concrete mix. This had a significant impact on the results, which meant that no environmental benefits were generated. Therefore, the study showed that to ensure the benefits of an application it was not only required to consider the technical advantages, but also the environmental savings that contributed to sustainable construction.
期刊介绍:
Engineering Sustainability provides a forum for sharing the latest thinking from research and practice, and increasingly is presenting the ''how to'' of engineering a resilient future. The journal features refereed papers and shorter articles relating to the pursuit and implementation of sustainability principles through engineering planning, design and application. The tensions between and integration of social, economic and environmental considerations within such schemes are of particular relevance. Methodologies for assessing sustainability, policy issues, education and corporate responsibility will also be included. The aims will be met primarily by providing papers and briefing notes (including case histories and best practice guidance) of use to decision-makers, practitioners, researchers and students.
