FOAMED CEMENT COMPOSITIONS CONTAINING METAL SILICIDES USABLE IN SUBTERRANEAN WELL OPERATIONS
The invention relates to cement compositions containing a metal silicide such as an alkali metal silicide or an alkaline earth metal silicide. Upon mixing with water, the metal silicide reacts to generate hydrogen gas, a silicate, and heat—each of which is advantageous for the large variety of uses to which cements are put. The invention relates to a foamable cement composition comprising about 99.999 wt % to about 98.5 wt % of a cement, and about 0.001 wt % to about 1.5 wt % of a metal silicide or a mixture of metal silicides. Concretes and grouts containing the cement composition are also disclosed. Other embodiments provide methods for forming cement structures, including in subterranean formations and wells.
