    Abstract
  • A granular crystalline calcium silicate hydrate has been synthesized through high temperature hydrothermal reaction at 160 ℃ and 80 MPa with CaO, Ca(OH)2 and white carbon black (a silica) as the major raw materials. Study on the effects of the synthesis product on the hydration process of oil well cement showed that the use of the synthesized calcium silicate hydrate caused the released heat of hydration of the cement to double, and was able to significantly accelerate the heat release process of the cement slurry. The particle sizes of the calcium silicate hydrate have some effects on the hydration process of the cement. When the particle size is in nano-scale, the rate of heat release and the total heat released of the cement slurry increase more obviously. By adding a specific amount of the calcium silicate hydrate into a cement slurry, the compressive strength of the set cement, the overall properties of the cement slurry and the set cement can all be improved. The study has shown that the ratio of SiO2/CaO of the cement affects its hydration process.
