Thank you for your response. My concern is that although cracks propagated during the test, they did not appear to affect the load-displacement graph from the tensile tester. I observed no noticeable drop in the load on the graph. In this situation, would the test still be considered a failure?
Can anyone provide me some info about how humidity can affect the compressive strength of insulation materials- Calcium Silicate (Medium density)?
What does it mean if cracks propagate during the compressive test?
