Prestressed Concrete MCQ with answer and solution

Very easy level · Asked in State AE, State JE, GPSC AE

In a pre-stressed concrete member, it is advisable to use

Solution

Concept

Materials in prestressed concrete

Step-by-step solution

1. High strength concrete resists high compressive stresses and has smaller losses. 2. High tensile steel keeps the prestress after losses.

Explanation

Both materials must be of high strength.

Why the other options are wrong

Low strength concrete or low steel strength would lose prestress.

Shortcut

PSC = high-strength concrete + high-tensile steel.

Correct answer: D) High strength concrete and high tensile steel
