Question 1.
What is the primary difference between the stress-strain behavior of plain concrete and fiber-reinforced concrete?
Show hintHide hint
Think about how each type behaves after reaching the peak load.
Question 2.
What are the two types of post-cracking behavior in FRC?
Show hintHide hint
One allows load to increase, while the other allows it to decrease.
3Question 3.
What characterizes the stress-strain behavior of fiber-reinforced concrete?
- Linear until failure
- Non-linear strain hardening
- Constant under load
Show hintHide hint
Think about how fibers influence the behavior after cracking.
4Question 4.
True or False: Deflection hardening indicates that load decreases post-cracking.
- True
- False
Show hintHide hint
Recall the characteristics of deflection hardening.
Question 5.
Design a fiber-reinforced concrete mix with optimal fiber volume to maximize strength without compromising workability. Discuss the parameters involved.
Show hintHide hint
Think about both the mechanical properties and processability.
Question 6.
Given a load-deflection curve from an experiment, identify the maximum load capacity and define the implications for structural design.
Show hintHide hint
Identify peak points in the load-deflection plot for guidance.
