Özet
The recycling process of construction and demolition waste, which started with brick pieces and brick dust used in the production of binder thousands of years ago, gained momentum after the second world war. Nowadays, the recycling activities of waste materials are sustained much more effectively by developing technology, machinery, and equipment. The obtained material by recycling waste concrete is called recycled concrete aggregate. And it has been stated in many experimental, analytical studies in the literature and more than one international material code that the recycled concrete aggregate, which meets specific material criteria, is an alternative to natural aggregate. This current study is carried out to give a different perspective and contribute to the literature on a not researched topic. Therefore, within the scope of this recent study, the structural topology optimization of structural members was performed by the isoline topology design method. The concrete properties of these members are considered with the natural concrete and the recycled aggregate concrete with four different recycled concrete aggregate ratios (25%, 50%, 75%, 100%). Besides, the structural topology optimization was performed by considering multi-material and single-material properties under similar loading conditions. As a result of the optimization process, the quantified optimization shapes indicated that the structural optimization behavior of multi-material structural members exhibits different optimization behavior depending on the recycled concrete aggregate ratios. However, considering the single-material situation, it is observed that the structural optimization behavior of structural members is similar for all concrete types. Finally, comparing the optimization shapes of natural concrete members with the recycled aggregate concrete members indicated that the structural topology optimization process applied to structural members incorporating natural concrete is also valid for recycled aggregate concrete members. In addition, a brief life cycle assessment of waste concrete was also carried out in this comprehensive study to emphasize the importance of recycling activities.
