Abstract

A clinker for use in cement manufacturing includes a cement clinker mixture having crystals of an element that is less electronegative than carbon and carbon bonded to at least a portion of the crystals.

First claim

What is claimed as new and desired to be secured by Letters Patent of the United States is:

1. A clinker product, comprising:
a cement clinker mixture to include iron crystals; and
carbon bonded to at least a portion of said iron crystals.

2. A clinker product as in claim 1 , wherein said clinker mixture comprises particles thereof not to exceed approximately 1 millimeter in diameter.

3. A clinker product as in claim 1 , further comprising additional carbon bonded to said carbon bonded to at least a portion of said iron crystals.

4. A clinker product as in claim 1 , wherein said carbon is covalently bonded to said iron crystals.

5. A clinker product as in claim 1 , wherein said carbon includes allotropes of carbon.

6. A clinker product as in claim 3 , wherein said additional carbon includes allotropes of carbon.

7. A clinker product, comprising:
a cement clinker mixture to include crystals of an element that is less electronegative than carbon; and
carbon bonded to at least a portion of said crystals.

8. A clinker product as in claim 7 , wherein said clinker mixture comprises particles thereof not to exceed approximately 1 millimeter in diameter.

9. A clinker product as in claim 7 , further comprising additional carbon bonded to said carbon bonded to at least a portion of said crystals.

10. A clinker product as in claim 7 , wherein said carbon is covalently bonded to said crystals.

11. A clinker product as in claim 7 , wherein said carbon includes allotropes of carbon.

12. A clinker product as in claim 9 , wherein said additional carbon includes allotropes of carbon.

13. A clinker product, comprising:
a cement clinker mixture defined by particles thereof having a diameter not to exceed approximately 1 millimeter, said clinker mixture including iron crystals;
carbon bonded to at least a portion of said iron crystals; and
additional carbon bonded to said carbon bonded to at least a portion of said iron crystals.

14. A clinker product as in claim 13 , wherein said carbon is covalently bonded to said iron crystals.

15. A clinker product as in claim 13 , wherein said carbon and said additional carbon include allotropes of carbon.
