End User application of specific wording in the requirements for cylinder curing in section 10.2.1 do not match the spirit and intent of concrete testing as currently written. The thermal mass of concrete cylinders is greatly different than that of the product that they represent. Current wording may actually serve to yield an as tested concrete strength that is not necessarily representative of the product that the cylinder represents which has a much larger thermal mass and may not be subjected to the same time / temperature maturity cycle as the smaller cylinder.
