“…Due to the advantageous capabilities, the pozzolanic material is a prospective substitution to ordinary Portland cement, [8] [9] [10]. Various factors show that the pozzolanic activity of a certain material depends mostly on its chemical and mineralogical composition, and moreover, on the amorphous phase content, the dihydroxylation degree, the material's specific surface, and the water to binder ratio of the blended mixtures, [11].…”

“…38 Considering the complicated conditions in the downhole, temperature and pressure would be important factors affecting the cementing quality. 39 In a thermal recovery well, the oil well cement sets at low temperature at the beginning but then works at high temperatures for a long period during the production process. In consideration of this circumstance in the downhole, cement slurries were initially cured at 75 C at atmospheric pressure for 7 days, and then, these cement pastes were placed into the high temperature curing chamber at a temperature of 200 C and pressure of 10 MPa for 7 days, which could simulate the downhole condition.…”

“…Many additives have been proposed to improve the quality of Portland cement based on OWC. Addition of phosphogypsum (Hua, Wang and Yao, 2016) and meta-kaolin (Bu et al, 2016) decreases permeability of hardened OWC. Aluminum powder and nano meta-kaolin decrease the volume shrinkage, silica powder increases the strength and reduce the porosity (Costa et al, 2017;El-Gamal, Hashem and Amin, 2017;Liu, Bu and Guo, 2013), CaCL 2 or NaCl accelerates the hardening, bentonite decreases the slurry density and polypropylene glycol reduces the foam in the Portland a cement based the OWC (Broni-Bediako, Joel and Ofori-Sarpong, 2016), mullite (3Al 2 O 3 •2SiO 2 ) (Han, Chen and Li, 2007) and corundum (Chen et al, 2015) increase high-temperature strength.…”
