Abstract

See full text

A hardened cement produced by setting a cement slurry including graphene comprising bioderived renewable graphene (BRG), a cement, and water. The graphene of the cement slurry comprises, consists essentially of, or consists of BRG, and the cement slurry comprises at least 0.2 (e.g., from about 0.2 to about 20) percent graphene comprising BRG by weight of cement (% graphene bwoc). The hardened cement produced by allowing the cement slurry to set has one or more enhanced mechanical properties (e.g., increased Young's modulus (YM), increased compressive strength (CS), or increased resiliency as indicated by an increased reduction in a ratio of YM/CS) relative to a same hardened cement produced by allowing to set a same cement slurry comprising a same total amount of graphene, with synthetic graphene (SG) in place of at least a portion of the BRG. Methods of cementing with the cement slurry are also provided.
