2. Flexural Strength Test

Try these first

1. 1.

   What is the primary purpose of the flexural strength test?

   Hint

   Consider the forces acting on the material.

2. 2.

   Name the two common loading methods used in the flexural test.

   Hint

   Think about how load could be spread across a beam.

3. 3.

   What is the primary function of the flexural strength test?

   • To measure compressive strength
   • To assess tensile strength under bending
   • To evaluate bond strength

   Hint

   Think about what happens when concrete is loaded in a bending manner.

4. 4.

   True or False: Third-point loading applies a single load at one-third span distance.

   • True
   • False

   Hint

   Visualize the loading configuration on a beam.

5. 5.

   A concrete beam with dimensions of 100 mm x 100 mm x 500 mm fails with a load of 15 kN during the flexural strength test. Calculate its flexural strength using both center-point and third-point loading formulas.

   Hint

   Make sure to substitute the right values into the formulas and calculate each method independently.

6. 6.

   If the dimensions of a beam are doubled, how does that affect its flexural strength based on the original loading conditions?

   Hint

   Think about how changing the physical dimensions could impact structural performance under bending.
