Question

Which of the following cement is used in the high-temperature application?

• A. Expansive cement
• B. High-Alumina cement
• C. Portland blast-furnace slag cement
• D. Portland pozzolan cement

Answer 1

The correct option is B High-Alumina cement

Because of their relatively high cost, calcium aluminate cements are used in a number of restricted applications where performance achieved justifies costs:

1. In construction concretes, where rapid strength development is required, even at low temperatures.
2. As a protective liner against microbial corrosion such as in sewer infrastructure.
3. In refractory concretes, where strength is required at high temperatures.
4. As a component in blended cement formulations, for various properties such as ultra-rapid strength development and controlled expansion are required.
5. In sewer networks for their high resistance to biogenic sulfide corrosion.
