Question

Which of the following option is correct?

(a) Standard consistency (%) = (wt of water added/ wt of cement) *100

(b) Standard consistency (%) = (wt of water added- wt of cement) *100

(c) Standard consistency = (wt of water added/ wt of cement) *100

(d) Standard consistency (%) = (wt cement/ wt of water) *100

I had been asked this question by my school principal while I was bunking the class.

Origin of the question is Standard Consistency Test in section Types of Cement and Testing of Cement of Concrete Technology

Answer 1

Correct option is (a) Standard consistency (%) = (wt of water added/ wt of cement) *100

Easiest explanation: To determine the standard consistency, we need to divide the weight of water to cement and then multiply it with 100 to get the percentage of standard consistency.
