1. A method for cementing in a wellbore comprising:
introducing a conduit into a wellbore, wherein the conduit comprises a reactive metal element disposed on an exterior of the conduit, wherein the reactive metal element is disposed between a pair of retaining elements which are disposed on the conduit, wherein a spacer element is disposed on the conduit on each of the opposing sides of the retaining elements relative to the reactive metal element, wherein the spacer elements are outside of the retaining elements relative to the reactive metal element; wherein the retaining elements are cup seals, end rings, or stamped rings; wherein the spacer elements comprises a polymer-based material, and wherein the reactive metal element comprises a reactive metal having a first volume;
circulating a cement over the exterior of the conduit and the reactive metal element;
setting the cement; wherein the set cement comprises a void;
then contacting the reactive metal element with a fluid that reacts with the reactive metal to produce a reaction product having a second volume greater than the first volume; and
contacting a surface of the cement adjacent to the reactive metal element with the reaction product.
