2.1. Objective

Try these first

1. 1.

   What is the primary objective of the compressive strength test?

   Hint

   Think about the performance indicators of concrete.

2. 2.

   Name one standard code used for testing flexural strength.

   Hint

   Consider the governing bodies for construction standards.

3. 3.

   What is measured by the compressive strength test?

   • Flexural Limit
   • Maximum Load before Failure
   • Bond Strength

   Hint

   Remember what compressive strength indicates.

4. 4.

   True or False: The bond strength test measures the direct tensile strength of concrete.

   • True
   • False

   Hint

   Consider what each test is designed to evaluate.

5. 5.

   Analyze a case where a concrete beam failed under bending. Identify possible contributing factors and suggest tests to conduct.

   Hint

   Think about both testing methods and structural integrity.

6. 6.

   Propose a method to improve bond strength in low-grade concrete.

   Hint

   Reflect on the principles of good concrete mixing and bonding.
