Question

In a brick cavity wall, the inner and outer leaf is __________ brick thick.

(a) Half

(b) One

(c) One and a half

(d) Two

I have been asked this question in a national level competition.

My question is from Cavity Walls in division Cavity Walls & Partition Walls of Construction & Building Materials

Answer 1

Correct choice is (a) Half

The best explanation: In a brick cavity wall, the inner and outer leaf is half brick thick. However, if the superimposed loads are very heavy, then the thickness of the inner leaf is increased in the multiple of half brick thickness.
