Synthesis, characterization and hydration analysis of a novel epoxy/superplasticizer oilwell cement slurry - Some mechanistic features by solution microcalorimetry

► A new epoxy/polyacrylate-modified oilwell cement slurry was synthesized. ► The morphological features of the new slurry were preserved after contact with HCl. ► The hydration processes were well fitted to a three-parameter kinetic model. ► Diffusional growth is the main mechanistic feature of new cement slurry hydration. ► The new cement slurry has good features for using in acidic environments of oilwells.
