... Abstract When Portland cement sheath is submitted to temperatures above 110 °C in oil well wellbore conditions, the compressive strength retrogression phenomenon is observed. This occurs due to the conversion of calcium silicate hydrate (C-S-H) to unstable phases, resulting in low compressive...
