Question

Cracks in plastering may be caused by settlement of the building, by the use of inferior materials or by bad workmanship.

(a) True

(b) False

The question was posed to me at a job interview.

Origin of the question is Analysis of Rates of Plastering and Pointing in section Analysis of Rates of Civil Engineering Drawing

Answer 1

Correct choice is (a) True

Easy explanation: However, due to none of these, cracks may yet ensue by the too fast drying of the work, caused through the laying of plaster on dry walls which suck from the composition the moisture required to enable it to set, by the application of external heat or the heat of the sun, by the laying of a coat upon one which has not properly set, the cracking in this case being caused by unequal contraction, or by the use of too small a proportion of sand.
