1.1. Based on Function

Try these first

1. 1.

   What is the purpose of chemical admixtures?

   Hint

   Think about how they change the behavior of concrete.

2. 2.

   Name one type of mineral admixture.

   Hint

   Consider by-products of industrial processes.

3. 3.

   What do chemical admixtures primarily affect?

   • Short-term properties
   • Long-term properties
   • Surface properties

   Hint

   Think about how they modify workability or setting time.

4. 4.

   True or False: Mineral admixtures are always synthetically produced.

   • True
   • False

   Hint

   Consider where these materials come from.

5. 5.

   A construction project requires high flowable concrete with minimal water use due to limited supply. Which admixture would you choose and why?

   Hint

   Think about the type of admixture that improves flow without adding water.

6. 6.

   In extreme hot weather, large pours are scheduled for a building foundation. Discuss potential admixtures that would be useful and their roles.

   Hint

   Consider admixtures that address setting time and workability.
