ABSTRACT
The specimens fabricated were of cylindrical and prismatic shape. The same mortar mix was made for all of them: water-cement (CEM I 42.5 R/SR) ratio of 0.5 and sand-cement ratio of 3. In some of the specimens were embedded a carbon steel B 500 SD bar of 8 mm in diameter. The specimens were cured at 20 ± 2ºC and 100% relative humidity in a chamber during 28 days.
