Method and apparaatus for curing concrete

A method for optimizing the curing of concrete poured into concrete forms, comprising the steps of:

• a. laying a plurality of spaced-apart plastic tubes into said concrete forms prior to pouring said concrete, placing respective ends of said tubes outside said forms;
• b. connecting the ends of said plurality of spaced-apart plastic tubes to a source of liquid and a liquid pumping system, whereby said liquid may be pumped through said tubes laying in said concrete forms;
• c. pouring liquid concrete into said forms and immersing said tubes into said liquid concrete;
• d. adjusting the temperature of said source of liquid, whereby the curing of said concrete may be optimized;
• and
• e. flowing said liquid through said tubes until said concrete hardens, and disconnecting the flow of said liquid through said tubes, and disconnecting said tubes from said source of liquid and said pumping system;
• whereby said tubes remain embedded in said hardened concrete.

An apparatus for curing concrete poured into forms, comprising:

• a. a reservoir for retaining a supply of liquid, and a pumping system connected to said reservoir for placing said liquid under a predetermined pressure;
• b. a temperature control system connected to said reservoir for controlling the temperature of liquid in said reservoir and delivered by said pumping system;
• c. a plurality of hose segments laid into said concrete forms at spaced-apart positions, the respective ends of said hose segments positioned outside said forms;
• and
• d. a first liquid manifold connected to one set of the respective ends of said hoses, and a second liquid manifold connected to a second set of the respective ends of said hoses, one of said manifolds further connected as a return to said liquid reservoir, and the other of said manifolds further connected to said pumping system.
