Self-repairing cement polymer composites and processes of making and using same

A method of forming a self-repairing cement-polymer composite matrix, comprising the steps of:

• introducing a cement-polymer composite-forming slurry comprising a cement-containing material, an epoxide polymer and/or epoxide oligomers thereof, a crosslinking agent, and an optional phase-separation inhibitor combined in an aqueous medium to a receiving location so as to contact structures and materials therein;
• curing the composite-forming slurry to form a self-repairing and self readhering cement-polymer composite matrix comprising chemical bonds between compounds therein and the structures and materials in the receiving location;
• and
• dynamically self-repairing structural breaches in the composite matrix by reforming chemical bonds between compounds therein and/or with the structures and materials bonded thereto restoring at least partial strength thereto and/or reducing permeability by up to about 90% therein.
