Abstract

A variety of methods and compositions are disclosed, including, in one embodiment, a settable composition comprising: water; and a cementitious component having a calculated reactive index.

First claim

What is claimed is:

1 . A settable composition comprising:
water; and a cementitious component having a calculated reactive index.

2 . The composition of claim 1 wherein the particle size of the cementitious component has been adjusted to adjust the calculated reactive index.

3 . The composition of claim 2 wherein the particle size of the cementitious component was adjusted to have a mean particle size of about 1 micron to about 350 microns.

4 . The composition of claim 2 wherein the cementitious component comprises a ground cementitious component.

5 . The composition of claim 2 wherein the particle size of the cementitious component was reduced to a mean particle of about 15 microns or less.

6 . The composition of claim 1 wherein the settable composition has a density in a range of about 4 pounds per gallon to about 20 pounds per gallon, and wherein the water is present in an amount sufficient to form a pumpable slurry.

7 . The composition of claim 1 wherein the cementitious component comprises at least one component selected from the group consisting of Portland cement, calcium aluminate, gypsum, a pozzolanic material, kiln dust, and any combination thereof.

8 . The composition of claim 1 wherein the settable composition further comprises a second cementitious component, wherein the cementitious component and the second cementitious component have different reactive indexes.

9 . The composition of claim 8 wherein the cementitious component and the second cementitious component have reactive indexes that vary by a factor of at least about 2:1.

10 . The composition of claim 8 wherein the cementitious component and the second cementitious component have reactive indexes that vary by a factor of at least about 100:1.
