Question

You are asked to construct a massive dam, the type of cement you will use, is?

(a) Ordinary Portland cement

(b) Blast furnace slag cement

(c) White cement

(d) Low heat cement

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

My question is from Residential Accommodation for Various Classes of Employees in chapter Planning of Building and Colony of Civil Engineering Drawing

Answer 1

The correct answer is (d) Low heat cement

Easy explanation: Dam construction will involve mass concreting where heat of hydration is the major concern which if not monitored will cause crack in the bulk of the dam which is undesirable, hence low heat cement is preferable in this type of concreting.
