چکیده
This paper discusses the state-of-the-art of fine recycled concrete aggregates (fRCA), focusing on their physical and chemical properties, engineering properties durability concretes with fRCA. Based systematic review published literature, it is impossible to deduce without any further research guidelines tools introduce widespread application fRCA in new whilst keeping cement contents at least same or preferably lower. Namely, what still missing knowledge key physico-chemical relation quality mix performance. sets foundations for better understanding obtained either from parent specifically produced laboratory, controlled crushing sieving field structures. By comparing natural aggregates, limiting are identified as high water absorption fRCA, moisture state agglomeration particles adhered mortar. As such, continuous hard be obtained, even though they may more terms chemistry. Advanced characterization techniques technology needed account design. • The progress (fRCA) reviewed. material (non)structural applications systematically presented. Future challenges development discussed.

Increased Durability of Concrete Made with Fine Recycled Concrete Aggregates Using Superplasticizers
This paper evaluates the influence of two superplasticizers (SP) on the durability properties of concrete made with fine recycled concrete aggregate (FRCA). For this purpose, three families of concrete were tested: concrete without SP, concrete made with a regular superplasticizer and concrete made with a high-performance superplasticizer. Five volumetric replacement ratios of natural sand by F...
متن کاملLow Cycle Fatigue Behavior of Concrete with Recycled Concrete Aggregates
A comparison of concrete containing recycled concrete coarse aggregates and natural coarse aggregates subjected to high strain, low cycle compressive fatigue is presented. Using a strain based feedback control loop, concrete cylinders are compressed at 15µε/s to a specified strain then unloaded to zero stress for 10 cycles. After cycling, all samples are loaded to a strain of 0.008. Direct conc...
متن کاملPerformance of High-strength Concrete Made with Recycled Ceramic Aggregates
Recent scientific concerns to achieve sustainability in construction have suggested the implementation of using recycled aggregate in concrete because it has the potential to reduce the demand for extraction of natural raw materials and decrease the volume of wastes landfilled. In this respect, this study aims to investigate the suitability of using ceramic tile (CT) and ceramic sanitary (CS) w...
متن کاملBonding Behavior of Deformed Steel Rebars in Sustainable Concrete Containing both Fine and Coarse Recycled Aggregates
In order to assess the bond behavior of deformed steel rebars in recycled-aggregate concrete (RAC) incorporating both fine and coarse recycled aggregate, pull-out tests were carried out in this study on 16-mm diameter deformed steel rebars embedded concentrically in RAC. The concrete was designed using equivalently mixed proportions of both recycled coarse aggregate and recycled fine aggregate....
