Question 1.
What does fresh concrete exert against formwork?
Show hintHide hint
Think about how fluids behave.
Question 2.
Why should formwork be watertight?
Show hintHide hint
Consider the consequences of leakage.
3Question 3.
What is the primary reason for formwork to be watertight?
- To increase the setting time
- To prevent loss of water and maintain workability
- To reduce construction time
Show hintHide hint
Think about how water affects concrete curing.
4Question 4.
True or False: Fresh concrete does not exert any pressure on formwork.
- True
- False
Show hintHide hint
Consider how fluids behave under pressure.
Question 5.
In the design of a new concrete structure, assess how varying temperatures affect fresh concrete pressure on formwork in a high-rise construction setup.
Show hintHide hint
Consider how temperature affects fluid dynamics and setting times.
Question 6.
Evaluate a failure case where formwork buckled during placement. Identify the factors that could have contributed to this incident and suggest improvements for future projects.
Show hintHide hint
Think of the physics behind structures under strain.
