Question

Reinforced brickwork uses __________

(a) First class bricks with high compressive strength

(b) First class bricks with moderate compressive strength

(c) Second class bricks with high compressive strength

(d) Second class bricks with moderate compressive strength

The question was posed to me at a job interview.

I'd like to ask this question from Composite Masonry in chapter Composite Masonry of Construction & Building Materials

Answer 1

The correct answer is (a) First class bricks with high compressive strength

Easiest explanation: Reinforced brickwork is the one in which the resultant composite masonry is capable of bearing any kind of tensile or shear stresses in addition to the compressive stresses. Therefore, it uses first class bricks with high compressive strength in order to impart great strength to the resulting masonry.
