Abstract
A dry, free-flowing cement composition that comprises dry cement particles and flow inducing particulates that comprise solid adsorbent particulates having adsorbed thereon a flow inducing chemical, ethylene glycol, and water. The water is present in an amount from 5% to 30.3% by weight of the solid adsorbent particulates, the ethylene glycol is present in an amount from 3.25 to 20% by weight of the solid adsorbent particulates, and the flow inducing particulate is present in an amount from 0.005% to 5% by weight of the cement. The dry, free-flowing cement composition is free-flowing at temperatures at least as low as 10° F.
