<p>Microsilica slurries having a microsilica solids content of at least about 50% by weight which are stable for extended periods of time are provided. The slurries have a pH in the range of about 5.0 to 8.5 and comprise microsilica, an aqueous carrier medium, an anionic dispersant for the microsilica, and a chelating agent capable of chelating multivalent cationic impurities in the microsilica. Also provided are a method of preparing the slurries and hydraulic cement compositions containing same.</p> |
