ENVIRONMENTAL IMPACT OF CONCRETE RECYCLING,

2007-1-17  This paper presents the results of a research study on the environmental impact produced by the recycling of concrete originating from construction and demolition waste (CDW). The aim of the study was to implement a life cycle inventory (LCI) of the concrete recycling phases. It was carried out in Spain, with data collected from the various recycling processes involved in the mobile crushing plants operating in Catalonia. The values have been compared with the environmental impact produced during the extraction processes of natural resources (gravel and sand) from different European databases. The main emissions (CO2, NOx, SO2, SOx, and dust) with major influence on the greenhouse effect, acidification, and eutrophication were considered. The recycling

The Environmental Impact of Recycled Concrete

2012-8-14  Creep is affected by the young’s modulus. Gómez-Soberón, (2002) calculated the young’s modulus for a concrete which uses recycled aggregates only and is 10% lower than concrete made of natural aggregate. The difference of young’s modulus increases to 18% for tests carried out at 90 days. This means that concrete with recycled aggregates can be more suitable to long term deformation forces. Retraction of concrete with recycled aggregates was measured by Katz (2003) and the results show that this concrete has retraction around 0.7mm/m in comparison with 0.32mm/m encountered in conventional concrete. Li (2008) explains that the superior retraction observed in concrete with recycled
