Concrete runways, roads, highways and slabs on grade and methods of making same

A method comprising:

• placing a plastic cementitious material in an insulated concrete form, wherein the cementitious material consists essentially of:
• approximately 30% to approximately 80% by weight portland cement, the remaining cementitious material comprising one or more pozzolanic materials;
• and
• allowing the cementitious material to at least partially cure in the insulated concrete form such that the temperature of the cementitious material, when plotted versus time, forms an initially ascending curve followed by a descending curve, wherein the descending curve lasts for greater than or equal to 24 hours.

• and
• allowing the cementitious material to at least partially cure in the insulated concrete form such that the temperature of the cementitious material achieves a temperature greater than the same cementitious material would achieve in a non-insulated concrete form and the temperature remains at a greater temperature for a time greater than or equal to 24 hours.
