Question 1.
What does compressive strength indicate?
Show hintHide hint
Consider what happens when you apply force to concrete.
Question 2.
Name one method used to test compressive strength.
Show hintHide hint
Think about different shapes used in tests.
3Question 3.
What is the primary purpose of conducting compressive strength tests?
- To determine water absorption
- To assess load-bearing capability
- To check for color
Show hintHide hint
Remember, it's about how concrete responds under pressure.
4Question 4.
True or False: The cube test can be performed at any stage of the construction process.
- True
- False
Show hintHide hint
Think about the curing schedule.
Question 5.
A construction site pours concrete in temperatures below 5°C. Discuss the implications of this choice and propose a testing schedule to account for potential strength delays.
Show hintHide hint
Think about how temperature affects hydration.
Question 6.
A batch of concrete used for a bridge construction is tested and shows its compressive strength at 28 days is significantly below expected values. What steps should be taken next?
Show hintHide hint
Review what could cause strength variations in concrete.
