| 摘要 | Provided herein are cementitious compositions comprising a non-aqueous fluid and an alkali-activated material. The non-aqueous fluid can include a natural oil, a synthetically derived oil, one or more surfactants, or a combination thereof. In some embodiments, the non-aqueous fluid can include an oil based mud, a synthetic based mud, or a mixture thereof. The alkali-activated material in the cementitious composition can be derived from an aluminosilicate material and an alkaline activator. In some embodiments, the aluminosilicate material includes fly ash. The alkaline activator can be selected from an alkali-hydroxide, an alkali-silicate, an alkali carbonate, an alkali bicarbonate, an alkali sulfate, and a mixture thereof. Provided herein are also wellbore servicing composition, such as compositions to reduce lost circulation of drilling fluids or cement a casing into the borehole, comprising the cementitious compositions and methods for preparing and using the cementitious compositions. | ||||||
