Laboratory tests, Details, Quality of test resultsAbstract
The present work describes important information on the implementation and parameter evaluation by unconfined compression and diametral compression tests for tensile strength determination. The described details will hopefully contribute to the development of better quality and innovative academic research with more practical equipment, to the selection of more realistic directions for research under development and to a deeper knowledge of test procedures, avoiding runtime errors that may influence significantly the final results. It is expected that this article may have wide dissemination among those who develop their research in the laboratory directly performing their tests, in order to promote the transfer and enhancement of scientific and technological knowledge, in support of students, teachers and professionals, through the ability to create, lead and propagate technology and expertise within the academic circles.
