2.3.1. Consistency Index

According to the fresh state of the mortar, the consistency index was defined according to the ABNT NM 13276 [24]. Each mortar was produced following the methodology prescribed by the standard, being mechanically mixed for 90 s (speed 1) in the mortar (power of 0.3 CV at 62 rpm with a capacity of 5 L) and then placed in rest for 15 min covered by a damp cloth. After resting, the mixture was manually homogenized for 30 s with a spatula and placed in the mold on the flow table (MC—119), where it was subjected to 30 strokes with a socket. After the last fall from the table, the average value of the diameter measured in three different directions was calculated to verify the consistency of each mixture produced, being established by the aforementioned standard that the margin is 260 ± 5 mm. Measurements were performed in relation to the table plane, considering the vertical, horizontal and inclined readings.
