Abstract:
Methods for adjusting the mechanical properties of cement systems include preparing a cement slurry containing water, an inorganic cement and at least two minerals. At least one of the minerals has a specific gravity higher than that of the cement at least one of the minerals has a specific gravity lower than that of the cement. The slurry is allowed to harden and form a set cement. The concentrations of the cement and the minerals may be varied such that the slurry has a constant solid volume fraction and a constant Compressive Strength vs. Effective porosity slurry density.

Claim (Index 8):
A method for cementing a subterranean well, comprising:\n (i) preparing a cement slurry comprising water, an inorganic cement and least two minerals, wherein at least one of the minerals has a specific gravity lower than the cement and at least one of the minerals has a specific gravity higher than the cement, and the minerals are chemically inert with respect to the cement; (ii) placing the slurry in the well; and (iii) allowing the slurry to harden and form a set cement; wherein, the concentrations of the cement and the minerals are varied such that the slurry has a constant solid volume fraction and a constant slurry density.
