17.3.1. Cement

Try these first

1. 1.

   What is the primary type of cement used in concrete pavements?

   Hint

   Think about the most commonly referenced type in civil engineering.

2. 2.

   What do the numbers 43 and 53 represent in cement grades?

   Hint

   Consider what strength values are standard.

3. 3.

   Which type of cement is most commonly used for pavements?

   • Blended Cement
   • Ordinary Portland Cement
   • Gypsum Cement

   Hint

   Consider the commonly referenced type in civil engineering.

4. 4.

   True or False: Fineness of cement decreases its reactivity.

   • True
   • False

   Hint

   Think about the relationship between particle size and chemical reactions.

5. 5.

   Design a concrete mix for a high-traffic pavement requiring fast-setting cement. Consider the environmental impacts and choose the appropriate type of cement.

   Hint

   Evaluate the balance between strength and environmental considerations.

6. 6.

   You have two types of blended cements, both claiming high durability. How would you determine which one is better for severe conditions?

   Hint

   Consider specific environmental impacts on pavement durability.
