BOREHOLE CEMENT SLURRY ADDITIVE, METHOD FOR STORING SAME, BOREHOLE CEMENT SLURRY, AND BOREHOLE CEMENTING METHOD
Provided are: a borehole cement slurry additive that is capable of suppressing the generation of free water from cement slurries in any environment, whether cold regions, mild regions, or hot regions; and a method for storing the same. The borehole cement slurry additive contains: an aqueous dispersion of silica having an average particle size of 3-200 nm as determined via dynamic light scattering; and a compound having an alcoholic hydroxyl group as a dispersion stabilizer, the compound being included in an amount of 1-30 mol per 1,000 g dispersion medium in the aqueous silica dispersion.
