Which cement type is used for general-purpose cement?

• A. Type II
• B. Type I
• C. Type III
• D. Type IV

Answer: (B)

General-purpose cement refers to standard Portland cement used for ordinary concrete projects without special performance needs. This is the cement designed for typical pours, providing normal setting and strength development suitable for most building applications like foundations, slabs, and structural walls. It’s chosen when there’s no requirement for sulfate resistance, rapid strength gain, or notably reduced heat of hydration. If a project has sulfate exposure or needs to manage heat in a large pour, other types are more appropriate: Type II offers moderate sulfate resistance and lower heat of hydration; Type III develops strength faster at earlier times; Type IV is a low-heat option used for very large masses, though it’s less common today.
