This method is designed to indicate a procedure that may be used as a guide for the calculation of the amount of ice required to be added to a concrete mixture in lieu of water in order to lower the temperature of the concrete as placed to a specified value. The calculations described by this method do not contemplate that heat losses due to batching, mixing, transporting, or placing will be individually measured.

This method of test outlines a procedure for determining, under standard laboratory conditions, the unit moisture loss from a standard mortar specimen when covered by a membrane-forming compound, and for determining the spray ability of the compound at 40 F.
