1. A method of curing concrete comprising:

  • (a) providing a memory device having a predetermined temperature profile stored therein, wherein the predetermined temperature profile continually varies temperature as a function of time and comprises a first period of temperature increase followed by a first period of temperature decrease followed by a second period of temperature increase followed by a second period of temperature decrease, wherein the predetermined temperature profile comprises a plurality of temperatures and each temperature'"'"'s corresponding elapsed time from initiation of the predetermined temperature profile, and wherein the predetermined temperature profile is stored in the memory device prior to step (d) below;

    (b) placing a quantity of concrete in a thermally insulated container having a sufficient quantity of water therein so that the concrete is surrounded by the water;

    (c) repeatedly detecting the temperature of the quantity of water;

    (d) repeatedly comparing the detected temperature of the quantity of water to the temperature of the predetermined temperature profile corresponding to the time of the detected temperature; and

    (e) selectively adding heat to and removing heat from the quantity of water in the insulated container in response to step (d) so that the temperature of the quantity of water follows the predetermined temperature profile during the curing of the quantity of concrete, wherein the heat selectively added to the quantity of water comes from an electrically heated element in thermal contact with the quantity of water, wherein the heat selectively removed from the quantity of water comes from a cooling element in thermal contact with the quantity of water and wherein the selective addition of heat to the quantity of water and the removal of heat from the quantity of water is controlled by a computing device.
