compressive strength of concrete core determination astm

ASTM C42 / C42M - 20 Standard Test Method for

3.5 The measured compressive strength of a core will generally be less than that of a corresponding properly molded and cured standard cylinder tested at the same age. For a given concrete, however, there is no unique relationship between the strengths of these two types of specimens (see Note 3).The relationship is affected by many factors such as the strength level of the concrete, the in ...
