Question

The __________ bonds are used when was become weak in the longitudinal direction due to filling of thicker wall in the headers only.

(a) Dutch bond

(b) Facing bond

(c) Raking bond

(d) English cross bond

The question was posed to me in a job interview.

I need to ask this question from Bonds in Brickwork topic in section Stone and Brick Masonry of Construction & Building Materials

Answer 1

Correct option is (c) Raking bond

For explanation I would say: As the filling of  thicker wall is done by headers only, such wall become weak in the longitudinal direction. The raking on inclined bonds are used in such cases as remedial measures. The raking or inclination should be in opposite direction in alternate courses of the Raking bond.
