Question 1

What is the purpose of the Compressive Strength Test?

  • To determine the water quality
  • To evaluate the strength of concrete
  • To test for impurities in water

💡 Hint: Consider what aspect of concrete the test directly measures.

Question 2

True or False: Concrete should achieve 100% of the strength of distilled water mixes.

  • True
  • False

💡 Hint: Look back at what percentage we discussed for the test.

Challenge Problems

Push your limits with challenges.

Question 1

A construction team is considering using water from a nearby lake known for high organic content. They conduct a compressive strength test but find their concrete only reaches 70% of the distilled water strength. Discuss the potential impacts and what actions the team should take.

💡 Hint: Evaluate the risks of using contaminated water.

Question 2

If a concrete mix using test water yields a compressive strength of 30 MPa after 7 days, what can be inferred about the strength of the mix made with distilled water? Calculate the minimum acceptable strength.

💡 Hint: Apply the 90% rule we discussed for compressive strength.
