摘要: Hydration phenomena at cement/water interfaces drive the characteristics of oil-well cement slurries. In this study, new epoxy-modified slurries were synthesized. The characterization has suggested presence low amounts portlandite in slurry with higher content polymerized epoxy resin. hydration processes studied by heat-conduction microcalorimetry. energetic and enthalpic data all exothermic nature. cumulative heat release curves have shown multilinearity kinetic processes. microcalorimetric well fitted to multistep Avrami model. It was found that present a good potential be used environmental-friendly operations.
