“…water absorption, amount of attached mortar, size, and texture) and the mechanical (i.e. parent concrete strength) characteristics of the RCAs as well as the methods adopted for the extraction process of RCAs from CDW (Koper et al, 2017; Laserna and Montero, 2016; Lotfi et al, 2015; McGinnis et al, 2017; Xiao et al, 2007). Different authors investigated different techniques to improve the mechanical performances of RACs such as treatment methods for RCA (Dimitriou et al, 2018; Ismail et al, 2017; Katkhuda and Shatarat, 2016; Kim et al, 2018), use of different mix proportions (Fathifazl et al, 2009a; Gupta et al, 2015; Leite and Santana, 2019; Rajhans et al, 2019), and inclusion of fiber reinforcements (Hanumesh et al, 2018; Wang et al, 2019).…”
