  1. Liquid Stone Huward Fontenot MEEN-3344-001 Spring 2004

  2. Background • Created by BJ Services Company • Made from Portland Concrete (API Class H) • Normally begins hydration immediately after being mixed • Can be slowed down • Often irreversible

  3. Composition • Suspending agent • Kerrigena – keeps viscosity low, makes pumping easier • Plasticizer • Maintains fluid state, keeps gel strength down, keeps low thickness • Set Retarder • Proprietary organic acid - stops hydration process

  4. Using Liquid Stone • Activator • Added to the Liquid Stone to initiate hydration process • Returns to Portland Concrete state (maintains similar properties) • If used in high temperature areas, the high temperature can act as the activator • Optimum temperature range is up to 450ºF

  5. Uses • Used in remote locations • Concrete normally transported dry and mixed on site • Easier to handle • Used in offshore oil rigs • No pre-mixing necessary • Easily poured

  6. Benefits • Slurries can be mixed for specific uses • Ranges in density (8.1 – 20.0 ppg) • Maintains normal compressive strength • Easily pumped • Environmentally safe • Personnel have minimal exposure to dust • Compatible with other cements • Reduces losses during mixing and transport • Can be stored for several months in liquid state
