What would an engineer of record want to see when specifying ASTM C780 for CMU construction on a non-load bearing single wyth wall. The test method calls out several possable tests including compressive strength, splitting tensile strength, air content and board life.
At what stages ie 7 days, 14 days or 28 days after casting should or would the EOR want to see results.
wouldn't treplets of fully grouted and ungrouted prisms tested for strength make for a more confident (competent) test?
