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. Also no provision is made for storing specimens at temperatures except in the moist cabinet or moist room. The proposed changes brings the testing more into line with C109 by requiring all specimens to be stripped from the molds at 1 day of age and requiring curing of specimens in saturated lime water at the temperatures used for the test 3 C [ 5 F] as required in the existing Section 8.
