Q: You are asked to construct a massive dam, the type of cement you will use is............
  • A. Ordinary Portland cement
  • B. Rapid hardening cement
  • C. Low heat cement
  • D. Blast furnace slag cement
Correct Answer: Option C - Low heat cement : A low heat cement evolution is achieved by reducing the contents of C₃S and C₃A which are the compounds evolving the maximum heat of hydration and increasing C₂S. The use of low heat cement – • Mass concrete construction. • Hot weather concrete. • Where if necessary to produce resistance to sulphate attack.
