Discussion Forum : UPSC Civil Service Exam Questions - Section 1 (Q.No. 46)
46.
Consider the following strengths of concrete :
1. Cube strength
2. Cylinder strength
3. Split-tensile strength
4. Modulus of rupture
The correct sequence in decreasing order of these strengths is
3, 4, 2, 1
3, 4, 1, 2
4, 3, 2, 1
4, 3, 1, 2

Cylinder=0.8 x cube strength;

Split tensile strength = 0.66 x modulus of rupture.
So, option A is correct.

1 2 4 3 is right.

Agree @Anbu.

Civil engineers don't read the question they just matching the answers but they must know that cube strength is compressive strength which always greater than the modulus of (tensile strength) so the correct sequence is 1,2,4,3.
