Recycled concrete could be a sustainable way to keep rubble out of landfill

Results of a new five-year study of recycled concrete show that it performs as well, and in several cases even better, than conventional concrete. Researchers 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.
