Cement-based mixtures including particles of glass-reinforced plastic are disclosed. In some cases, the mixtures may include particles of glass-reinforced plastic having an average diameter less than approximately 100 microns and/or at least 95% particles of the glass-reinforced plastic in a mixture may have a diameter less than approximately 100 microns. The mixtures may be a dry cement mixture, a cement slurry, or a solidified piece of cement. In some cases, the mixtures may be used to form a solidified oil-field cement plug disposed in and filling a wellbore. A method of making a cement-based mixture includes reducing one or more glass-reinforced plastic components of a used, expired, or defective product into granular particles and blending the granular particles with a prefabricated cement powder or a cement paste to form a substantially homogenous mixture having less than approximately 50% of the granular particles by volume.
A dry mixture, comprising:
A mixture comprising:
A method of making a cement-based mixture, comprising:
A solidified oil-field cement plug disposed in and filling a wellbore, wherein the solidified oil-field cement plug comprises particles of glass-reinforced plastic having an average diameter less than approximately 100 microns, and wherein at least some of the particles of glass-reinforced plastic comprise a polymer material of the glass-reinforced plastic.
