Evaluation of the Rheological Behavior of the Samples
The samples had its rheological behavior evaluated by
the HAAKE rheometer model RHEOSTRESS RS-1. For
this study it was used the cone-plate (C35=2Ti) sensor
and data were analyzed by the software Rheowin 3. The
assays performed were: (1) yield stress, using a shear stress
of 0.01–0.5 Pa, for 180 seconds, (2) stress sweep, with shear
stress of 0.01–1200 Pa, in a frequency of 1 Hz, (3) creep and
recovery, with duration of 300 seconds and shear stress of
0.5 Pa, and recovery also with 300 seconds, returning to
0 Pa.[14] These tests were performed at 25C.
