1. A method comprising:
preparing a resin containing cement composition comprising:
cement;
water;
defoamer; and
a silane based aqueous soluble resin, wherein the silane based aqueous soluble resin comprises a glycidyl alkoxy silane resin comprising 3-glycidoxypropyl trimethoxy silane and an amino alkoxy silane hardener comprising n-(3-(trimethoxysilyl)propyl)ethylenediamine, wherein the 3-glycidoxypropyl trimethoxy silane and the n-(3-(trimethoxysilyl)propyl)ethylenediamine represents at least 10% by volume of the resin containing cement composition, wherein the resin is in an amount of about 21% to about 40% by volume of the silane based aqueous soluble resin, wherein the silane based aqueous soluble resin has a glass transition temperature of greater than 230° F. (110° C.); and
introducing the resin containing cement composition into a wellbore.
