2.4.1. Capillary Absorption

To carry out this test, it was necessary to make 3 prismatic parts for each sample, using Portland cement types CP II, CP III and CP V, with cures of 7, 14 and 28 days. For this, it was based on the ABNT NM 13279 [32] standard, which describes the necessary procedures for the preparation of prismatic parts.

After finishing the curing days, the capillary absorption test was carried out, guided by the ABNT NM 15259 [33] standard. It was necessary to use a tray with water and an individual platform made of rubber material to lift the prismatic parts, allowing minimal contact with the water.
