Astm C1074 Predicts The Strength Of Concrete In Place
Aug 16, 2021 Use two cylinders to obtain the compressive strength at each of the test agesusually 1, 3, 7, 14, and 28 days. If any cylinders deviate from their mean strength by more than 10, test an extra cylinder. We care about early-age strengths for several reasons. In prestressed concrete, the production facility is on a 24-hour cycle.
