Given the size of the construction sector in our country and the lack of quality control, the recovered agrega sector in our country must be established and developed to evaluate the concrete that is already and will go out during the improvement and destruction work in the future urban transformation process of broken urbanization structures. As we see in examples such as Belgium, Denmark, Spain and Japan, recycled aggregates obtained from manufacturing and destruction waste are possible to be used in the concrete industry as large aggregates and thin aggregates. While the agrega that will be provided from building waste helps to eliminate environmental problems, it is also important for the storage of waste and the considerable reduction of the energy consumption used during the agrega production (breaking + removing + transportation). In this experimental study, which examined the availability of recovered aggregate in concrete production with the contribution of high oven curve, the concrete series of fine, large and both aggregates (at the same time) recovered aggregate used in traditional concrete production were produced and produced on concrete samples, physical and mechanical tests were carried out in the days 7, 28 and 90. In the production of concrete used as a mineral contribution, the polished granule high oven curve (ÖGYFC) is stored with cement at 0.15% and 30% ratings. For natural aggregate series, the target resistance C30/37 is produced, with the water/binding ratio of 0.50 using natural aggregates, with a dose of 380, which is thought to be exposed to the XS1 (corrosion risk caused by chlorine in sea water), with the target resistance C30/37 is produced. In the production of recycled aggregate series; recycled aggregates taken from the recycling facility are brought to the same granulometry as natural aggregates and with the same dosage are produced concrete where the water/binding ratio is used. The comparison of concrete produced with natural agrega and recovered agrega, the unit weight in fresh concrete, processable (break) and air content experiments, the unit weight in hardened concrete, pressure resistance, drawing resistance, ultrasound, key water absorption, volume water absorption experiments have been studied. The results show that large and thin natural aggregates can also be used by changing place at high rates with both physically and mechanically recovered aggregates, using a folded high oven curve. The performance of recovered aggregate concrete series, which contains a 30 percent high oven curve, is better, especially in the 28th and 90th days, compared to natural aggregate concrete series.
