3.6. Procedure

Try these first

1. 1.

   What is the main purpose of the compressive strength test?

   Hint

   Think about the importance of load-bearing in structures.

2. 2.

   Name one equipment used in the flexural strength test.

   Hint

   Remember the devices used to apply load during testing.

3. 3.

   What is the formal definition of compressive strength?

   • A: Maximum load supported divided by surface area.
   • B: The resistance to bending.
   • C: The resistance to pulling.

   Hint

   Think about which test measures resistance under pressure.

4. 4.

   The bond strength test is crucial for assessing which of the following?

   • True
   • False

   Hint

   Remember the role of reinforcement in concrete structures.

5. 5.

   A concrete beam of size 150 mm x 150 mm x 700 mm fails at a load of 40 kN using third-point loading. Calculate its flexural strength.

   Hint

   Ensure you know the dimensions well.

6. 6.

   Discuss how curing conditions can influence the outcomes of destructive tests on concrete strength.

   Hint

   Consider the role of moisture and temperature in curing processes.
