Abstract. In this research, grinding energy of selected rock samples collected from South West Nigeria was determined using comminution theory in order to evaluate suitability of rock for aggregate production. Bond Work Index (BWi), Aggregate Impact Value (AIV) and Aggregate Crushing Value (ACV) of samples was characterized and correlated.

Jul 04, 2015 The aggregate crushing value (ACV) test provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load (Al-Harthi 2001). The values obtained in ACV tests are influenced by intrinsic geological factors such as petrology, petrography, and fabric (Ramsay et al. 1974 ).
