3.2. Excellent Compressive Strength

Try these first

1. 1.

   What is compressive strength?

   Hint

   Think about how much load concrete can bear.

2. 2.

   What is the typical compressive strength range of Ordinary Portland Cement concrete?

   Hint

   Consider the values mentioned in class.

3. 3.

   What is the primary measure of a material's ability to withstand compressive loads?

   • Tensile Strength
   • Compressive Strength
   • Flexural Strength

   Hint

   Think about which term relates to 'compression'.

4. 4.

   True or False: High-strength concrete can achieve compressive strengths above 100 MPa.

   • True
   • False

   Hint

   Recall the numbers mentioned in class.

5. 5.

   A new construction project needs a foundation with a compressive strength of at least 30 MPa. If the current mix design yields a strength of 25 MPa, what could you suggest to enhance the strength, considering admixtures?

   Hint

   Consider industry practices for mix adjustments.

6. 6.

   Describe an experiment to test the compressive strength of your concrete sample and how you would analyze the results.

   Hint

   Recall the testing standards we discussed in the previous class.
