ABSTRACT:
Aqueous-based microsilica slurries having resistance to gelling and settlement of solids are provided. The slurries contain amino alcohols as stabilizing agents, the amino alcohols having the formula ##STR1## wherein R.sup.1 and R.sup.2 are each individually hydrogen or a linear or branched alkyl group containing 1 to 6 carbon atoms; R.sup.3 is a linear or branched alkylene group containing 1 to 8 carbon atoms; and R.sup.4 and R.sup.5 are each individually hydrogen, a linear or branched alkyl group containing 1 to 8 carbon atoms, or a linear or branched hydroxyalkyl group containing 1 to 8 carbon atoms.
Also provided are hydraulic cement compositions comprising a hydraulic-cement binder, microsilica, and an amino alcohol of the invention.
