Environmental Assessment of Recycled Aggregate
The paper presents an environmental assessment of construction and demolition (C&D) waste production. The use of C&D waste carries a number of positive and negative aspects. These aspects should be compared to find the optimal way for recycled aggregate use. This study presents results of a fuel consumption survey of Czech recycling companies. Furthermore, there are evaluated impact categories of the connection with the diesel production and diesel burning during recycling process. Finally, it is shown comparison with database data for mining of natural aggregate. In addition, the results of previous investigation of the impact of natural aggregate substitution by recycled aggregate in concrete mixtures on mechanical and deformation properties of recycled concrete are presented.
