you will need about 4 cuyds for your project.
about 26.4 is the volume i think.......

30 minutes
25 feet is equal to 300 inches. The radius of a hole is half its diameter, which equals 4 inches. The volume of the cylinder is given by the formula v = [Pi]r2h, so the volume of your hole is 3.14 * 16 * 300 = 15080 cubic inches. There are 1728 cubic inches to the cubic foot, so you'll need about 8.75 cubic feet of concrete, which is about a third of a yard. (More exactly, that's a cubic yard, but concrete guys just say "yard.")
It typically takes about 24 to 48 hours for 6 inches of concrete to cure completely.
It typically takes about 28 days for 4 inches of concrete to fully cure and reach its maximum strength.
It takes at least 3 days to harden.
At least a month to dry and another week to harden
it takes 28 days to fully cure, It would be advisable not to drive on it before that because of micro cracks, which will continue to migrate through time, causing spiderwebbing outside of your control joints, Depends on the cement used some quick cure cements can harden in an hour
you will need about 4 cuyds for your project.
7.1
Wood putty typically takes around 24 hours to fully harden once applied.
387 cubic feet. This is because 43x18x0.5 (as six inches is 1/2 of a foot) =387.
is a scinentific method
Salt dough typically takes 24-48 hours to fully harden, depending on the thickness of the dough and the humidity in the environment.
15 cubic yards
