This document shows the results of calibration of a prototype of compression machine, designed and built for failure of mortar cylinders, in accordance with the regulation INV E 2012. In the process, 14 and 28 days of curing specimens were used, and they were tested both in the prototype and in the calibrated machine. Based on the results obtained, the cracking stresees of tested specimens were calculated and a comparative analysis was made for the prototype and the calibrated machine. As a result, it was determined that the prototype indicates values between 97% and 98% of similarity compared to the calibrated machine. With the above it is concluded that the reliability of the results allows the prototype to be used as a support instrument for laboratory practices in Mechanics of Materials course.
