Abstract:

Cylinder-compressed concrete (SSB) is a newly used construction material compared to traditional concrete and is often preferred in road and barge construction in terms of its advantages such as easy and fast production, low cost, the use of resources used in traditional concrete production as raw materials. As in traditional concrete production, in SSB production, the conservation of the resources used and the re-evaluation of waste materials in production is important in terms of reducing damage to the environment, as well as reducing energy losses and costs occurring during the transport, storage and disposal of waste materials in a way that does not harm the environment. In this study, waste concrete compressed with the cylinder was reused in SSB production by melting in the appropriate size. Waste aggregates are used as a large aggregate at a ratio of 0, 50% and 100%. Except for waste aggregates, a large aggregate of dolomite aggregate, a thin aggregate of natural sand, a binding CEM I 42,5R Portland cement and a water/cement (s/s) ratio of 0.36 SSB production was carried out. When SSB samples are produced, each stage is compressed in two stages for approximately 15 seconds. The samples produced were removed from the pattern one day later, until the day of the test, they were kept in the curry pool with a curry saturated water. The unit volume weight of the produced concrete, 7 and 28 days of pressure resistance, ultrasound transition speed, elasticity module and stretching resistance are determined. As a result of the experimental study, the waste SSB aggregate has achieved a relatively homogeneousness in providing the physical characteristics that determine the quality of concrete, such as the Los Angeles dive resistance, water absorption, the potential for reuse in the SSB production, and the re-evaluated waste SSB aggregates can contribute economically and sustainably.
