Question

Which test can be performed without skilled labour?

(a) Probe test

(b) Bend liquid test

(c) Dye penetrant test

(d) Torsion test

The question was posed to me in a job interview.

The query is from Destructive and Non-Destructive Tests topic in section Testing of Concrete of Concrete Technology

Answer 1

The correct answer is:

(a) Probe test

The probe test is a simple non-destructive test that can often be performed without highly skilled labor. It involves probing the surface of concrete to assess its strength, moisture content, or surface condition. This can usually be done using basic equipment and doesn't require specialized knowledge or training compared to other tests like the dye penetrant or torsion tests, which typically need skilled operators.
