“…It should be noted that the use of thick RCA (up to 30%) is usually recommended, but it is often considered necessary to add superplasticizers [ 48 ] to achieve the required workability of the new concrete. These materials can improve the durability of concrete [ 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 ]. Due to the scarce works found in the literature, further research efforts are needed to determine the effect of the RCA as well as the partial substitution of OPC with SCBA in the corrosion performance of these novel concretes [ 55 , 56 , 57 ].…”
