Within the scope of the "Urban Transformation" studies that started in 2012, it is aimed to demolish and reconstruct the buildings in terms of earthquake safety. It is extremely important to recycle and reuse construction and demolition wastes as raw materials without causing environmental problems. In the experimental study, the rubble obtained from the demolished houses as part of urban transformation projects in Büyükçekmece District of Istanbul was selectively separated at the source and crushed with the help of a aggregate crusher. Recycled aggregates of 5.6 – 11.2 mm and 11.2 – 22.4 mm in size were replaced with natural aggregates in different proportions by volume and recycled aggregate concrete series were produced. In the production of concrete mixtures, silica fume and fly ash were used in different proportions as mineral additives. Compressive and splitting tensile strength tests were carried out 28 days after casting. It has been obtained that the use of the recycled aggregates with presence of mineral additives can contribute to both the environment and the economy in terms of sustainability in the construction sector.
