A) Support and elevate steel reinforcement off the ground during concrete pouring.
B) Provide lateral support to formwork, preventing it from collapsing during concrete placement.
C) Used to create a defined edge for concrete slabs and structures.
D) Reinforce concrete to increase its tensile strength and prevent cracking.
E) Used to secure formwork and hold it in place during concrete pouring.
F) Prevent water vapor from seeping into the concrete, protecting against moisture-related issues
G) Provide additional strength and stability to the concrete structure.
H) Used to reinforce the concrete and control cracking due to temperature and shrinkage
Question 3. Select the correct answer.
