Question

What does grade 33 cement indicate?

(a) Tensile strength of 33 kN/m^2

(b) Tensile strength of 33 N/mm^2

(c) Compressive strength of 33 kN/m^2

(d) Compressive strength of 33 N/mm^2

The question was posed to me during an online exam.

This interesting question is from Grades of Cement topic in section Materials for Construction of Basic Civil Engineering

Answer 1

The correct option is (d) Compressive strength of 33 N/mm^2

To explain: The grades of cement are specified by IS 1489-1991.  Cements are usually graded based on their compressive strength.
