Question

Group I contains representative stress-strain curves as shown in the figure, while Group II gives the list of materials. Match the stress-strain curves with the corresponding materials.

Group I
P. Curve J
Q. Curve K
R. Curve L

Group II
1. Cement paste
2. Coarse aggregate
3. Concrete

Accepted Answer

P - 2; Q - 3; R - 1. The correct option matches the stress-strain characteristics of each material: Curve J (P) represents the behavior of coarse aggregate, which is typically more linear and less ductile; Curve K (Q) corresponds to concrete, which shows a more complex behavior with a defined yield point; and Curve L (R) reflects the properties of cement paste, which is more brittle and has a lower strength compared to concrete.
