This practice covers procedures for casting and curing cylinder and beam specimens from representative samples of fresh concrete for a construction project. The concrete used to cast the 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 casting specimens from concrete not having measurable slump or for casting specimens requiring other sizes or shapes. This standard was formerly designated as standard method of test T 23.
