3.2. Fluid Transport

Try these first

1. 1.

   What is permeability?

   Hint

   Think about how fluids interact with porous materials.

2. 2.

   Name a mechanism of fluid transport in concrete.

   Hint

   Recall the key processes discussed.

3. 3.

   What is the primary factor influencing fluid transport in concrete?

   • Aggregate Quality
   • Temperature
   • Humidity

   Hint

   Consider what materials help improve concrete structure.

4. 4.

   True or False: Capillary suction involves the drawing of water into concrete through small pores.

   • True
   • False

   Hint

   Think about how water behaves in small spaces.

5. 5.

   How would you design a concrete mix to minimize fluid transport for a coastal structure? List specific strategies.

   Hint

   Consider how materials and mixing impact durability.

6. 6.

   Calculate the potential increase in corrosion risk if the permeability of a concrete structure is doubled. Explain your reasoning.

   Hint

   Think about how permeability changes might affect the overall condition over time.
