Abstract
Disclosed herein are cement compositions and methods of using set-delayed cement compositions in subterranean formations. An embodiment includes a method of cementing in a subterranean formation comprising: providing a cement composition comprising water, pumice, hydrated lime, a set retarder, and a strength enhancer, wherein the strength enhancer comprises at least one material selected from the group consisting of cement kiln dust, slag, amorphous silica, a pozzolan, and any combination thereof; introducing the cement composition into the subterranean formation; and allowing the cement composition to set in the subterranean formation.
