Zusammenfassung:Compositions are provided that relate to cementing operations. A settable composition may comprise wollastonite, pumice, a calcium-ion source, and water, wherein the wollastonite may be present in an amount in a range of from 25% to 75% by combined weight of the wollastonite and pumice, and wherein the pumice may present in an amount in a range of from 25% to 75% by combined weight of the wollastonite and pumice and wherein the water is present in an amount in a range of from 40% to 200% by combined weight of the wollastonite and pumice. The settable composition has a density in a range of from 12 to 20 pounds per gallon. The calcium-ion source comprises lime and is present in an amount in a range of from 0.1 % to 25% by combined weight of the wollastonite and pumice. The settable composition is essentially free of Portland cement.
