ASTM C31 – Standard Practice for Making and Curing Concrete Test Specimens in the Field
This practice covers procedures for making and curing cylinder and beam specimens from representative samples of fresh concrete for a construction project.
The concrete used to make the molded specimens shall be sampled after all on-site adjustments have been made to the mixture proportions, including the addition of mix water and admixtures.
This practice is not intended for making specimens from concrete not having measurable slump or requiring other sizes or shapes of specimens.
This practice is not applicable to lightweight insulating concrete or controlled low strength material (CLSM).
