Question

The ratio of the amount of water to the amount of cement by weight is termed as the _______

(a) Aggregate-sand ratio

(b) Water-cement ratio

(c) Cement-water ratio

(d) Sand-aggregate ratio

This question was addressed to me during an online exam.

I'd like to ask this question from Cement Concrete Construction topic in section Cement Concrete Construction of Construction & Building Materials

Answer 1

The correct choice is (b) Water-cement ratio

For explanation I would say: It is found theoretically that the water required for Function is about 0.50 to 0.60 times the weight of cement. The strength and quality of concrete primarily depend upon the water cement ratio.
