Recycled Concrete as Aggregate for Structural Concrete Production

- the third concrete mix had 100% of recycled coarse aggregate (R100). As all the other variables were kept constant, this research enabled us to determine the influence of the coarse recycled aggregate amount (0%, 50% and 100%) on tested concrete properties. The following properties of concrete were selected for testing:
