15.2. Sulfate Resistance

Try these first

1. 1.

   What is sulfate attack?

   Hint

   Think about the consequences of chemical reactions in concrete.

2. 2.

   Name one material that can improve sulfate resistance in concrete.

   Hint

   Consider what by-products from industrial processes might be utilized.

3. 3.

   What is the main consequence of sulfate attack on concrete?

   • Increased Strength
   • Expansive Damage
   • Reduced Workability

   Hint

   Consider the effects of harmful reactions on structural materials.

4. 4.

   True or False: The addition of SCMs can help mitigate the effects of sulfate attack.

   • True
   • False

   Hint

   Think about how additives affect concrete properties.

5. 5.

   Design a concrete mix for a structure in a sulfate-rich environment. Specify the components and their proportions.

   Hint

   Think about the right proportion of cement, water, and enhancing materials.

6. 6.

   Analyze the impact of sulfate attack on a structure built with conventional concrete versus one using SCMs.

   Hint

   Consider the durability and resistance differences over time.
