2017-11-1 1. Introduction. Manufactured fine aggregates are being increasingly used as a more sustainable alternative to natural sands in different parts of the globe, as a response to the growing restrictions to the use of the natural material (Gonçalves et al., 2007, Anand and Reddy, 2014).Manufactured sands often differ from the natural product in respect to three main
