2.6 Cure
The healing period is called the time required for the cement action, and for Mehta
and Monteiro (2008), healing is nothing more than a set of factors that promote
hydration of the cement, especially the humidity, time and temperature, in order to
provide material strength. Therefore, the time required for the bricks reaches the
point of full resistance. According to ABCP (2002), the cement is partially cured in
7 days and reaches its best performance from 28 days as in Fig. 4. Twenty-eight days
was the time considered in the study, before performing the tests.
During this phase, samples were analyzed visually in order to realize inappropriate
behaviors such as cracks, blemishes, or other types of faults or changes visible to the
naked eye, as shown in Fig. 5.
