Question

Which of the following is not an advantage of rapid hardening cement?

(a) Faster construction

(b) Short curing period

(c) Light in weight

(d) Higher final setting time

This question was posed to me in an interview for job.

I need to ask this question from Types of Cement and Uses in portion Materials for Construction of Basic Civil Engineering

Answer 1

Correct answer is (d) Higher final setting time

Easiest explanation: The initial and final setting time of rapid hardening cement is the same as that of ordinary cement.  It attains higher strength in less time.  It develops the same strength of ordinary cement in four days rather than 28 days.
