“…Consequently, many workers have used rheological techniques to indirectly assess the physicochemical force between colloidal particles and the associated aggregation structure (Johnson et al, 1998;Abend and Lagaly, 2000;Hyun et al, 2002;Mpofu et al, 2003;Szekeres, 2004, 2006;Bossard et al, 2007;Shankar et al, 2010;Chemeda et al, 2014). Although the effect of ionic strength and pH on the rheological properties of clay mineral dispersion has been thoroughly studied (Abend and Lagaly, 2000;Duran et al, 2000;Ramos-Tejada et al, 2001;James, 2006, 2008;Szekeres, 2004, 2006), a detail description of particle interaction in calcium rich alkaline condition such as in lime solution is rarely presented in the literature.…”
