    A cement composition for use in a well that penetrates a subterranean formation comprises: a calcium aluminate cement or calcium magnesia cement; water; a fluid loss additive; and a suspending agent, wherein the suspending agent is a polymer and wherein the polymer: (A) is amphoteric; (B) has a molecular weight greater than 100,000; and (C) does not increase the fluid loss of the cement composition greater than 15% at a temperature of 145° F. (63° C.) and a pressure differential of 1,000 psi (7 MPa) compared to a cement composition consisting of the cement, the water, and the fluid loss additive. A method of cementing in a subterranean formation comprises: introducing the cement composition into the subterranean formation; and allowing the cement composition to set.
