- •
At 75 °C, the early-term strength of cement decreased with the increasing MK content.
- •
At 75 °C, the set cement with more MK showed higher long-term strength.
- •
Beyond 150 °C, samples M40 to M60 presented good strength in all test ages.
- •
Hydration products and structure would influence strength and porosity of cement.
- •
High dosage of MK cement is suitable for corrosion and high temperature conditions.
