“…Seven techniques are reviewed in this study, which determine the sample's maximum Acid Production Potential (APP) with its maximum Neutralization Potential (NP). These seven methods are (i) Acid-Base Accounting (ABA), (ii) Modified ABA (MABA), (iii) paste pH, (iv) Net Acid Generation (NAG), (v) Sequential NAG test (SNAG), (vi) Kinetic NAG test (KNAG) and (vii) Acid Buffering Characteristics Curve (ABCC) test (Ehinola and Adene, 2008;Komnitsas et al, 2009;Hesketh et al, 2010b;Huges et al, 2007;Miller et al, 1991;Pope et al, 2010;Shu et al, 2001;;Weber et al, 2004). Each test uses separate methods to evaluate the capacity for acid generation and neutralization.…”
