Abstract

The use of coarse recycled concrete aggregates on concrete applications can substantially reduce the environmental effects and the exhaustion of the natural resources. The researchers suggest that coarse recycled aggregates should be processed appropriately and used in applications with low strength concrete. This study was carried out to investigate the possibilities of using the coarse aggregate from concrete waste as coarse recycled aggregate in concrete. In the study, coarse recycled concrete aggregate (FRCA) was used in the ratio of 0, 10, 20, 30, 40, 50 and 100 % respectively in place of crushed sand. Compressive stress, unit weight and water absorption rates tests were determined for these concrete samples for 28 days. According to the test results, it was found that recycled aggregate could be used in place of fine aggregate up to 30%.

Özet

Beton üretiminde, geri dönüşüm beton agregalarının kullanımı, olumsuz çevresel etkilerini ve doğal kaynakların tüketilmesini önemli ölçüde azaltabilir. Araştırmacılar, geri dönüşüm agregalarının uygun bir biçimde işlenmesi ve düşük dayanımlı beton uygulamalarında kullanımını önermektedir. Bu çalışmada, beton atıklarından elde edilen iri agreganın geri dönüşüm agregası olarak betonda kullanım olanakları araştırılmıştır. Araştırmada; kırma iri agrega yerine %0, 10, 20, 30, 40, 50 ve 100 oranlarında iri geri dönüşüm beton agregası (İGDBA) kullanılmıştır. Beton örneklerinin 28 günlük basınç dayanımları, birim ağırlık ve su emme oranları belirlenmiştir. Elde edilen deney sonuçlarına göre; %30 oranına kadar İGDBA’nın beton üretiminde kullanılabileceği görülmüştür.
