Abstract

The invention comprises a method of forming a slab on grade. The method comprises placing a first layer of insulating material horizontally on the ground and placing plastic concrete for a slab on grade on the first layer of insulating material. The plastic concrete is then formed into a desired shape having a top and sides. A second layer of insulating material is placed on the top of the plastic concrete and the first and second layers of insulating material are left in place until the concrete is at least partially cured. The second layer of insulating material is then removed. The product made by the method is also disclosed. A slab on grade is also disclosed.

Claims

1-30. -30. (canceled)

31. 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.

32. The method of claim 31, wherein the descending curve lasts for greater than or equal to 48 hours.

33. The method of claim 31, wherein the one or more pozzolanic materials are slag cement, fly ash, silica fume, rice husk ash, metakaolin, or other siliceous, aluminous or aluminosiliceous materials that react with calcium hydroxide in the presence of water.

34. The method of claim 31, wherein the portland cement comprises approximately 30% to approximately 70% by weight portland cement.

35. The method of claim 31, wherein the portland cement comprises approximately 30% to approximately 60% by weight portland cement.

36. The method of claim 31, wherein the portland cement comprises approximately 30% to approximately 50% by weight portland cement.

37. The method of claim 31, wherein the insulated concrete form has an R-value of greater than 4.

38. The method of claim 31, wherein the insulated concrete form has an R-value of greater than 8.

39. The method of claim 31, wherein the insulated concrete form comprises a pair of rectangular, vertically oriented insulating layers horizontally spaced from each other.

40. The method of claim 31, wherein the insulated concrete form comprises a pair of rectangular, horizontally oriented insulating layers vertically spaced from each other.

41. 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 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.

42. The method of claim 41, wherein the portland cement comprises approximately 30% to approximately 70% by weight portland cement.

43. The method of claim 41, wherein the portland cement comprises approximately 30% to approximately 60% by weight portland cement.

44. The method of claim 41, wherein the portland cement comprises approximately 30% to approximately 50% by weight portland cement.

45. The method of claim 45, wherein the insulated concrete form has an R-value of greater than 4.

46. The method of claim 45, wherein the insulated concrete form has an R-value of greater than 8.

47. 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 temperature of the cementitious material achieves a temperature greater than the same cementitious material would achieve in a non-insulated concrete form and remains at a greater temperature for a time greater than or equal to 24 hours and wherein the descending curve lasts for greater than or equal to 24 hours.

48. The method of claim 47, wherein the portland cement comprises approximately 30% to approximately 60% by weight portland cement.

49. The method of claim 47, wherein the portland cement comprises approximately 30% to approximately 50% by weight portland cement.

50. The method of claim 47, wherein the insulated concrete form has an R-value of at least 4.
