“…Considerable work has been conducted to develop non-destructive methods (NDTs), due to its advantages. NDTs can provide reproducible measures of material quality in a specimen (or even a structure) without causing an extra damage to the element or the structure from which it is taken (Malhotra & Carino, 2010), in a very short period of time while maintaining moderate cost (Leshchinsky, 1991). Unfortunately, most of the NDTs are designed for concrete.…”
