1. Durability of Construction Materials

Try these first

1. 1.

   Define durability in construction materials.

   Hint

   What does a material need to do over time?

2. 2.

   List two factors affecting durability.

   Hint

   Think about what conditions might harm construction materials.

3. 3.

   What is the main purpose of assessing the durability of construction materials?

   • To reduce construction costs
   • To ensure long service life
   • To improve aesthetic appeal

   Hint

   Think about the long-term function of buildings.

4. 4.

   True or False: Higher permeability typically means better durability.

   • True
   • False

   Hint

   Reflect on how water affects concrete durability.

5. 5.

   Analyze a structure exposed to marine conditions. Discuss the strategies that would enhance its durability considering the potential risks of chloride attack.

   Hint

   Think about materials and constructions specifically designed for saltwater encounters.

6. 6.

   Evaluate the role of alkali-silica reaction (AAR) in affecting the durability of concrete structures. Provide solutions to mitigate its effects.

   Hint

   Remember the relationship between alkalis in concrete and reactive aggregates.
