The CEMHYD3D cement hydration model can be executed under a variety of curing conditions (isothermal, adiabatic, or user-programmed temperature history). Menu Selection 12 is used to specify a controlled temperature history to be used in the hydration process (Menu Selection 13). The user simply fills in a table of starting and ending times with the corresponding temperatures. A linear change in temperature with time is assumed between the starting and ending points. Currently, the table is limited to six separate entries which should be adequate to specify a steam curing profile, for example. In addition to the values for the table, the user also specifies a filename in which to store the temperature history so that it may be accessed later during the execution of the hydration module.
