Abstract

The invention comprises a method of curing concrete. The method comprises placing a concrete cylinder in an insulated container having a sufficient quantity of water therein so that the concrete cylinder is submerged in and surrounded by the water and selectively adding heat to the quantity of water in an insulated container, so that the temperature of the quantity of water follows a predetermined temperature profile.

First claim

What is claimed is:

1. A concrete curing device comprising:
a thermally insulated container sized and shaped for containing a quantity of water and a quantity of concrete surrounded by the quantity of water;
a heating element in thermal communication with the quantity of water and operative to add heat to the quantity of water;
a cooling element in thermal communication with the quantity of water and operative to remove heat from the quantity of water;
a temperature sensory in thermal communication with the quantity of water so that the temperature sensor detects the temperature of the quantity of water;
a computing device controlling the heating element and cooling element so that heat is selectively added to and removed from the quantity of water;
a memory device having a predetermined temperature profile stored therein, wherein the predetermined temperature profile 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;
wherein the computing device is operatively associated with the temperature sensor for 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
wherein the computing device is programmed to control the heating element and cooling element in response to the compared temperature of the temperature sensor and the predetermined temperature profile such that the temperature of the quantity of water follows the predetermined temperature profile as a function of time.

2. The concrete curing device of claim 1 , wherein the predetermined temperature profile covers a period of time from initiation to between 1 and 14 days.
