Method of reacting CO2 by emulsifying concrete and use in oilwell cementing

Abstract

A concrete emulsion comprising a cement, aggregate, water, and carbon dioxide is provided. The carbon dioxide may be liquid or supercritical and is dispersed in the concrete emulsion composition. A method of producing a concrete emulsion composition is also provided. The method includes mixing a cement, aggregate, and water to form a hydrated concrete composition, and emulsifying the hydrated concrete composition with liquid or supercritical CO2. An article comprising the concrete emulsion composition is provided. Further, a method of treating a wellbore comprising producing a concrete emulsion composition and pumping the concrete emulsion composition into a wellbore, and a method of manufacturing an article comprising producing a concrete emulsion composition and 3D printing the concrete emulsion composition are also provided.
