3.8. Compatibility with Reinforcement

Try these first

1. 1.

   What do thermal expansion coefficients of concrete and steel help to minimize?

   Hint

   Think about temperature changes.

2. 2.

   What is one way that concrete helps to protect embedded steel?

   Hint

   Consider the properties of concrete.

3. 3.

   What does the similar thermal expansion coefficient between concrete and steel prevent?

   • A. Cracking
   • B. Color Change
   • C. Weight Gain
   • D. Surface Roughness

   Hint

   Remember how temperature can affect materials.

4. 4.

   True or False: The bond between steel and concrete is purely due to glue.

   • True
   • False

   Hint

   Think about how surfaces interact.

5. 5.

   You are tasked to design a bridge with reinforced concrete. What measures will you take to ensure the bond between concrete and steel remains strong considering environmental factors?

   Hint

   Think about both materials' properties and external influences.

6. 6.

   Discuss the potential long-term effects on a structure if the thermal expansion of embedded steel is neglected during the design phase.

   Hint

   Consider how temperature affects both materials over time.
