Question 1

What is the minimum compressive strength for OPC after 28 days?

  • 20 MPa
  • 33 MPa
  • 50 MPa

💡 Hint: This is based on the standard requirements for concrete used in typical structures.

Question 2

True or False: The compressive strength test is conducted on cement paste, not on mortar cubes.

  • True
  • False

💡 Hint: Consider the materials used in the test.

Challenge Problems

Push your limits with challenges.

Question 1

A construction site used OPC mortar that showed a compressive strength of only 25 MPa at 28 days. Propose a detailed approach the engineers should take to resolve the issue.

💡 Hint: Consider what factors determine the strength outcomes.

Question 2

If a new type of cement claims to provide 50 MPa compressive strength at 28 days but fails in testing, discuss how this failure can impact project planning.

💡 Hint: Think about the ripple effect of strength in construction.
