Question

Reinforced brick work 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

I have been asked this question in an internship interview.

Origin of the question is Stone Composite Masonry topic in section Composite Masonry of Construction & Building Materials

Answer 1

Correct option is (a) First class bricks with high compressive strength

Explanation: Reinforced brick work 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.
