A study of the possibilities of using recycled concrete in the UAE for the production of structural concrete
Lakomá, Karolína ; Novosad, Petr (referee) ; Hela, Rudolf (advisor)
The thesis focuses on verifying the possibilities of utilizing recycled concrete aggregates originating from demolitions in the United Arab Emirates (UAE) in structural concretes for ready-mix concrete technologies. The theoretical part summarizes knowledge in the field of recycled concrete aggregates, their preparation, and production. It outlines the standard requirements for the UAE, the Czech Republic and globally. Additionally, it describes the influences of recycled aggregates on fresh and hardened concrete. The goal of the experimental section was to verify the resulting properties of natural and recycled aggregates. Moreover, the thesis addresses the formulation design for reference and recycled concretes. Tests for both fresh and hardened concrete were conducted based on these formulations. This work compares the achieved results with those obtained in another study from the Czech Republic which is also focused on the use of recycled concrete. Furthermore, an economic analysis comparing the prices of reference and recycled concretes on 1 m3 is conducted within the experimental section.
