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.
It is believed that the effects due to these factors are so widely variable from job to job and from time to time on any single job that they should be compensated for by the use of a temperature differential determined from field observations of the difference between calculated and actual temperatures.
