PG was previously crushed and sieved, while G was not pre-treated. The granulometric range of the equipment was 0.30 µm - 400.00 µm, and the data was processed by the CILAS program (version 2.56).

Based on the results, the main conclusions obtained were: the reactivity of WCB was enhanced with the reduction of particle diameter up to a specific limit, stabilizing when D 90% was greater than or ...
