Yet, this mechanical grind-ing method typically consumes a large amount of grinding energy and can be cost-inhibitive to the production of RCA concrete [16, 20-21]. The cost of grinding may be relatively higher than the cost of producing the NA. This makes the RCA concrete uncompetitive to the NA concrete.
