Question

___________ type of arch is constructed from ordinary un-cut bricks.

(a) Rough arch

(b) Axed arch

(c) Rough cut arch

(d) Gauged arch

I had been asked this question by my college professor while I was bunking the class.

My question is taken from Types of Arches in section Arches, Lintels, Stairs and Formwork of Construction & Building Materials

Answer 1

Correct answer is (a) Rough arch

To explain: A rough arch is used where appearance is of secondary importance or when it is intended to plaster the face of the arch. In order to prevent the thick end of mortar to become too large, such arches are constructed in rings of half bricks.
