Sustainable mixing

摘要

The construction industry is increasingly under pressure to ensure that it uses the most environmentally-friendly materials -especially asphalt and concrete - in its projects. This has meant that companies involved in the provision of construction materials are becoming increasingly technologically advanced. The use of materials that have been reclaimed has increased over recent years as companies become more aware of their environmental obligations and the realisation that there are significant advantages to using recycled aggregates.Indeed, a report produced last year by the University of British Columbia's Okanagan's School of Engineering claimed that recycled concrete can, in some cases, outperform conventional concrete.Researchers at the school conducted side-by-side comparisons of recycled and conventional concrete within two common applications - a building foundation and a municipal sidewalk. They found that the recycled concrete had comparable strength and durability after five years of being in service.
