  • ADMIXTURE FOR FLUIDIFYING A CEMENTITIOUS COMPOSITION WITH REDUCED CEMENT CONTENT
    Publication number: 20240059611
    Abstract: The application describes an admixture comprising a polymer as fluidifier of a cement composition comprising: from 20 to 64 wt. % clinker, from 5 to 60 wt. % activated clay, from 0 to 35 wt. % limestone, from 0 to 10 wt. % calcium sulfate, the proportions being relative to the dry weight of the cement composition.

  • Cement Slurry Compositions and Methods
    Publication number: 20150041134
    Abstract: A cement slurry composition is described as having cement, water, and organic polymer particles. The composition also includes non-ionic surfactants, which may contain ethoxylate groups or contain both ethoxylate groups and propoxylate groups in the hydrophilic part. The non-ionic surfactant acts to disperse the hydrophobic polymeric particles in the slurry, thereby reducing mixing time. The cement slurry composition is prepared and then pumped into the subterranean well and placed in a zone of the subterranean well. Time is then allowed for the cement slurry composition to set and form a solid mass in the zone.
