Question

The w/c ratio is kept in the range of  _______

(a) .1-.2

(b) .38-.52

(c) .83-1

(d) .25-.38

This question was addressed to me in quiz.

My doubt stems from No Fines Concrete, High Density Concrete in division Special Concrete and Concreting Methods of Concrete Technology

Answer 1

Correct choice is (b) .38-.52

For explanation I would say: The water cement ratio is kept within the range of 0.38-0.52. The water cement ratio should be chosen very carefully considering the cohesive nature of the materials which we are using.
