1. A method of remediating fractures in a cement structure comprising a cement composition comprising solid eutectic metal alloy particles, the method comprising:
pumping the cement composition comprising solid eutectic metal alloy particles downhole;
curing the cement composition comprising the solid eutectic metal alloy particles downhole to provide the cement structure comprising solid eutectic metal alloy particles;
then heating the cement structure and the cement composition with an external heat source to a temperature at or above a melting temperature of the solid eutectic metal alloy particles;
melting the solid eutectic metal alloy particles within the cement composition to provide liquid eutectic metal alloy, thereby allowing flow of the liquid eutectic metal alloy into fractures in the cement structure;
discontinuing heating the cement structure; and
cooling and solidifying the liquid eutectic metal alloy in the fractures of the cement structure, wherein the solid eutectic metal alloy particles are present in a concentration ranging from 1 to 50 wt % based on the cement composition.
