Other studies have reported the negative effect of prolonged grinding. Mucsi et al. claimed that during mechanical activation of lignite fly ash in stirred media mill, the compressive strength of the geopolymer samples increased with milling time up to certain fineness. After that, further grinding led to decrease in compressive strength.
