Question

Stones which are placed at regular interval right across the wall are known as _______

(a) Spalls

(b) Through stones

(c) Reveals

(d) Springer

I got this question at a job interview.

The question is from Terms Used in Stone Masonry topic in portion Stone and Brick Masonry of Construction & Building Materials

Answer 1

Right answer is (b) Through stones

For explanation I would say: If the wall is considerably thick, two through stones with overlap are provided. The area covered by the throw stones should be about one-fourth to one-half of the area of the wall surface.
