Slow setting increases the window of finishability. Which statement is correct?

Slow setting increases the window of finishability. Which statement is correct?

• A. True
• B. False
• C. Only under certain conditions
• D. No impact

Answer: (A)

Finishability refers to the period after placement when finishing operations can be performed before the concrete stiffens beyond workable consistency. Slower setting slows the hydration process, so the concrete stays plastic longer. That keeps it workable for more time, allowing you to finish it properly without rushing. So the finishing window is extended, making the statement true. (Keep in mind that too-slow setting can bring other issues like bleeding or surface dusting, but the basic effect on finishability timing is an extended window.)
