Which of the following types of cement is most commonly used for mass concrete work such as large foundations or dams?
- AOrdinary Portland Cement (OPC)
- BRapid Hardening Cement (RHC)
- CSulphate Resisting Cement (SRC)
- DLow Heat Cement (LHC)Correct
Solution
Concept
Low heat cement
Step-by-step solution
1. Mass concrete needs low heat of hydration to avoid thermal cracking.
Explanation
Low heat cement is used for dams and large foundations.
Why the other options are wrong
OPC and RHC generate more heat; SRC resists sulphates.
Shortcut
Dams = low heat.
Correct answer: D) Low Heat Cement (LHC)
