11.12.3. Core Sampling and Laboratory Testing

Try these first

1. 1.

   What is core sampling?

   Hint

   Think about extracting physical samples for analysis.

2. 2.

   What is the purpose of measuring compressive strength?

   Hint

   Consider what strength means in terms of load.

3. 3.

   What is core sampling used for?

   • A method to improve strength
   • To extract concrete samples for testing
   • A curing technique

   Hint

   Remember that it involves extracting a physical sample.

4. 4.

   True or False: Carbonation depth is measured to assess the potential corrosion of reinforcement bars.

   • True
   • False

   Hint

   Think about the effects of CO2 on concrete.

5. 5.

   Design a comprehensive sampling and testing plan for assessing the durability of an aging bridge. Include specific tests and expected outcomes.

   Hint

   Consider factors like location, type of tests, and the age of the structure.

6. 6.

   Given a concrete sample with high chloride content and significant carbonation depth, suggest a remediation strategy to enhance its durability.

   Hint

   Think about methods that address both chloride ingress and carbonation effects.
