But it is an important plot point to the beginning chapter of a four part story I’m writing.
Scenario: our poor hero has been ruthlessly drugged in a bar and awakens in chains in the bottom of a dilapidated Olympic sized pool. Evil drug dealer with organized crime connections arranges for shady contracting buddy(-ies?) to drive over from nearby construction site with cement trucks to bury him alive.
I need to know:
Which dries faster, concrete or cement? Whichever dries faster is the one I’ll actually use in the story.
About how many cement trucks would I need to fill the bottom of the pool, say, five feet deep in the deep end??
About how long would it be before three or four evil drug dealers could safely walk on the surface of the pool and satisfy themselves the deathtrap is escape-proof?
P.S. My hero still escapes.
