Question

Consider the following strengths of concrete:

1. Cube strength
2. Cylinder strength
3. Split-tensile strength
4. Modulus of rupture
The correct sequence in increasing order of these strengths is

A. 3, 4, 2, 1
B. 3, 4, 1, 2
C. 4, 3, 2, 1
D. 4, 3, 1, 2

Answer 1

The correct sequence in increasing order of these strengths is :A). 3, 4, 2, 1

3. Split-tensile strength

4. Modulus of rupture

2. Cylinder strength

1. Cube strength

Step-by-step explanation:

Compressive strength can be defined as the capacity of concrete to withstand loads before failure. Of the many tests applied to the concrete, the compressive strength test is the most important, as it gives an idea about the characteristics of the concrete.

Increasing order of these strengths would mean that the values start from the lowest and increase gradually.

The correct sequence in increasing order of these strengths is :

• 3. Split-tensile strength
• 4. Modulus of rupture
• 2. Cylinder strength
• 1. Cube strength

Cube strength refers to the compressive strength of concrete when tested using cubes.

Cylinder strength is also a measure of compressive strength but is tested using cylinders.

Split-tensile strength measures the resistance of concrete to tensile forces.

Modulus of rupture refers to the strength of concrete against bending or flexural stress.
