ABSTRACT:
The present invention provides resilient cement compositions and methods which are particularly useful in the construction and repair of oil and gas wells. The compositions have improved expansion properties and are basically comprised of a hydraulic cementitious material, rubber particles derived from automobile tires, sufficient water to form a pumpable slurry, and a dispersing agent.
