Which statement is true about the cement types?

• A. They All Have The Same Temperature Range
• B. Only One Coat Has A Different Temperature Range
• C. Rockwool Cement And Finishing Cement Have 1900F
• D. Finishing Cement Has A Range Of 1500F

Answer: (C)

The main idea here is how cement types are rated for temperature. Different cement mixes are formulated to withstand different maximum temperatures. In this context, rockwool cement and finishing cement are both rated to survive up to 1900°F, so they share that high-temperature capability. That makes the statement true: these two cement types have a 1900°F rating, which guides their use in high-heat environments like furnaces or kilns. If you think about other options, not all cement types have the same temperature limit—some are rated lower or higher depending on their composition. The idea that only one coat would have a different range isn’t standard for these materials, since both rockwool cement and finishing cement are specified to 1900°F. And the claim that finishing cement is limited to 1500°F doesn’t align with the 1900°F rating these materials commonly have.
