    Abstract
  • To improve the ability of set cement to resist carbonation-induced corrosion, the mobility, the strength of set cement and the depth of carbonation-induced corrosion in supercritical CO2 environment were measured of a cement slurry in which ultrafine slag was substituted for oil-well cement. This measurement was aimed to determine the appropriate amount of the slag to substitute cement. Using low-field NMR, XRD and SEM with energy dispersive spectroscopy, the mechanisms with which the substituting ultrafine slag affects the ability of the set cement to resist carbonation-induced corrosion was studied. It was concluded that when the substituting amount of the ultrafine slag is less than 40%, it helps improve the mobility of the cement slurry; when increasing the substituting amount of the ultrafine slag, the strength of the set cement first increases and then decreases, and the depths of the carbonation-induced corrosion first decrease and then increase. Compared with the reference sample, the cement slurry sample with substituting amount of 10% ultrafine slag has more gel pore developed while the number of capillary pores decreases. The cement slurry sample with substituting amount of more than 50% ultrafine slag has less gel pores and more capillary pores. The cement slurry sample with substituting amount of 30%-50% ultrafine slag has basically gel pores and no evident capillary pores. By associating the pore structure of the sample with the depth of the carbonation-induced corrosion, it was found that the sample containing substituting amount of 30%-50% ultrafine slag showed no significant corrosion, and this is relevant to the fact that it has no evident capillary pores. The sample containing substituting amount of 40% ultrafine slag has compact structure and no evident pores in the micromorphology. The hydration product of this sample is mainly fine fluffy-shaped CSH gel with low Ca/Si ratio, and contains less Ca(OH)2 mineral phase which is easily being corroded. Therefore, it is recommended that the appropriate substituting amount of ultrafine slag be around 40%.
