Abstract:
The toughness of set cement may be enhanced by incorporating partially cured waterborne resins in the cement matrix. A hardening agent is added to the waterborne resin, and the mixture is allowed to react for periods between about 1 min and 15 min. The waterborne resin with hardening agent is then combined with an inorganic cement to form a pumpable slurry.
