2.3.3. Mass Density To define the density of the mass, the mortar was prepared according to the ABNT NM 13276 [24] standard. Then, an empty rigid and cylindrical container was used, with a mass of 0.891 kg and a volume of 400 cm3, continuing the test guided by the ABNT NM To define the density of the mass, the mortar was prepared according to the ABNT NM 13276 [24] standard. Then, an empty rigid and cylindrical container was used, with a mass of 0.891 kg and a volume of 400 cm<sup>3</sup> , continuing the test guided by the ABNT NM 13278 [28] standard.

First, considering the plate in the funnel, the filter paper positioned at the bottom of the plate was moistened. With the aid of a vacuum pump, a suction of 51 mm of mercury was applied to the set, which was weighed, and its mass (mv) recorded. After this procedure, the set was filled with the mortar, thickened with 37 socket strokes, flattened,

Thus, with the set filled in the device, a suction of 51 mm of mercury was applied to the set, which was weighed, and its mass (ms) recorded. The entire continuation of the test was guided by the ABNT NM 13277 [29] standard. In addition to the three values (mv, ma, ms) recorded, the total mass of water (mw) and the mass of the anhydrous com-

According to the squeeze flow test, the samples with cement type CPV were prioritized. To evaluate the rate of hydration reactions of the mortars, the calorimetry technique (ASTM C1679-17) [30] was used, being tested in two dosages, only in the CPV, with the substitutions of 0% and 30%, subjected first to consistency and later to the calorimeter, in amounts of 111.9 g and 111.8 g, respectively. The cement type CPV was used because it does not contain added blast furnace slag and/or pozzolana in the composition, and it contains calcium sulfate and carbonate material in the limit of up to 10% ABNT 16697 [22]. This makes it easier to identify the changes caused by the residue next to the
