Flow behavior was modeled through Ostwald and Herschel-Bulkley equations. Experimental data fit adequately to the first one, showing no tq as well as apparent viscosity (r]a) (shear rate 20 s ) values ranging from 0.018 to 0.027 Pa.s, trend that showed a weak thickening effect of these fractions. Aqueous systems showed pseudoplastic behavior with values of exponential index of 0.85 and 0.73 for R 2-2 and R 2-3, respectively (Table 6). [Pg.1340]
