1. Rationale
Currently molds for compressive strength testing are stripped at either 24 or 72 hours after molding which creates an unnecessary complication to the procedure. The proposed change brings the testing more into line with C109 by allowing all specimens to be stripped from the molds at 1 day of age if instructed by the material manufacturer. If specific materials are required to remain in the molds for other time periods, those instructions are to be provided by the material manufacturer.
