1. A concrete curing system comprising:

  • a computing device;

    a quantity of concrete having a plurality of surfaces, the surfaces having largest surface area a surfaces thereof;

    insulating material covering all of the primary surfaces of the quantity of curing concrete, whereby at least a portion of the heat of hydration and moisture of the quantity of curing concrete is retained therein;

    a temperature detecting device associated with the quantity of curing concrete for detecting the temperature thereof, wherein the temperature detecting device is operatively associated with the computing device such that a signal corresponding to the temperature of the quantity of curing concrete is provided to the computing device;

    an electric heating element for selectively providing heat to the quantity of curing concrete;

    a controller operatively connected to the computing device and to the heating element such that the controller variably controls the amount of heat produced by the heating element in response to signals from the computing device; and

    control software for the computing device for;

    (a) detecting the temperature of the quantity of curing concrete;

    (b) comparing the detected temperature to a predetermined temperature profile, wherein the predetermined temperature profile varies temperature as a function of time; and

    (c) providing signals to the controller for selectively adding heat to the quantity of curing concrete in response to step (b) when the detected temperature is lower than the predetermined temperature profile, so that the temperature of the quantity of curing concrete follows the predetermined temperature profile for at least the first 24 hours of the concrete curing process.
