1. A method for introducing a settable composition into a wellbore, the method comprising:
- providing a settable composition comprising pumice, hydrated lime, a set retarder, and water, wherein the pumice, hydrated lime, and set retarder form a suspension in the water;
introducing the settable composition into a wellbore; and
allowing the settable composition to remain static in the wellbore, wherein the settable composition remains in a pumpable fluid state for a period of about 1 day or longer while static in the wellbore;
wherein the settable composition is activated thermally.
