22.3. Mechanism of Polymer Action

Try these first

1. 1.

   What is formed during the hydration of cement?

   Hint

   Think of the main product that provides concrete with strength.

2. 2.

   What does the polymer film do in concrete?

   Hint

   This helps in making concrete last longer.

3. 3.

   What is the main component formed during the hydration of cement?

   • Calcium Carbonate
   • Calcium Silicate
   • Calcium Silicate Hydrate

   Hint

   It’s an abbreviation you might remember!

4. 4.

   True or False: Polymer films reduce the permeability of concrete.

   • True
   • False

   Hint

   Think about what prevents water from entering.

5. 5.

   Propose a new polymer type to improve concrete strength in severe weather conditions. Justify your choice.

   Hint

   Consider what properties would be necessary for weather resistance.

6. 6.

   Analyze the long-term effects of using polymer-modified concrete instead of standard concrete in a coastal environment.

   Hint

   Focus on how saltwater penetration affects standard concrete.
