Abstract: The present invention provides strategies for improved control of fluid loss, hydration, settling, and separation of aqueous cementing compositions over a wide temperature and time range. The present invention is based at least in part upon water-effusing particles used as additives for the compositions, wherein the particles are activated to control rheology when water soluble portions of the particles are released in the presence of water.
