Blended cement is a combination of Type II or Type V cement with any of the SCM. Which of the following best reflects this statement?

• A. Type II cement with SCM
• B. Type I cement with SCM
• C. Type II cement with water
• D. Type III cement with SCM

Answer: (A)

Blended cement combines cement with one or more supplementary cementitious materials (SCMs) to modify properties like durability and heat of hydration. The description specifies that the base cement must be Type II or Type V, with an SCM added. The option that pairs Type II cement with an SCM fits this definition exactly, making it the best representation. Using Type I or Type III cement with an SCM uses a different base cement than described, and using water isn’t an SCM at all, so it doesn’t constitute blended cement.
