Abstract
Disclosed herein are methods and compositions for cementing. An example method may comprise providing a cement composition. The cement composition may comprise a composite cementitious material comprising a micronized particulate solid and a monophase amorphous hydraulic binder. The micronized particulate solid may have a mean particle size of about 500 microns or less. The cement composition may further comprise water. The method may further comprise introducing the cement composition into a subterranean formation; and allowing the cement composition to set.

A method of cementing comprising:
- introducing a cement composition into a subterranean formation, the cement composition comprising:
- a composite cementitious material comprising a micronized particulate solid coated with a monophase amorphous hydraulic binder, wherein the micronized particulate solid has a mean particle size of about 500 microns or less, wherein the micronized particulate solid has hydraulic and/or pozzolanic activity, wherein the monophase amorphous hydraulic binder is deposited on the micronized particulate solid, and wherein 20% or more of the surface area of the micronized particulate solid is coated with the monophase amorphous hydraulic binder;
- and
- water;
- and
- allowing the cement composition to set.
A cement composition comprising:
