What is Type II Portland cement used for?

• A. Moderate sulfate resistance and lower heat of hydration than Type I.
• B. Faster setting time than Type I.
• C. Higher heat of hydration than Type I.
• D. Special bonding with epoxy.

Answer: (A)

Type II Portland cement is formulated for moderate sulfate resistance and lower heat of hydration compared to standard Type I cement. This means it helps protect concrete from mild sulfate attack in soils or groundwater, while also keeping the temperature rise during curing lower. The reduced heat of hydration lowers the risk of thermal cracking in thicker sections or mass pours. It’s not chosen for faster setting, higher heat, or epoxy bonding capabilities, which are not features of Type II cement.
