The length of time that concrete takes to set, will depend on the temperature. It would take approximately 4 hours for concrete to set at a temperature of 80 degrees.
Assuming you pour to a thickness of 4", this area requires 4.75 cubic yards.
(22*6)/2 =66 qubic ft
3,800 square feet at a 4-inch depth requires 46.91 cubic yards.
Crushed concrete is sold by the ton. One dumptruck will haul between 13 and 15 tons. Your driveway should take around 30 tons if covered 4" thick.
Less than one.
What size bags of concrete and how big are the bricks? Makes a difference.
The answer will depend on the size of the concrete block!
7.1
15 cubic yards
15 cubic yards
To many!
How deep? 1 inch will take .7 yards
8.25 cubic yards of concrete
A driller, two spotters
It is about 166.67 cubic feet and you will need just over 6.17 cubic yards of concrete.
This all depends on the mix you want. I assume you mean cement when you mention the 80lb bag of concrete. I have pushed concrete in my day... Bag cement mix is the same as concrete. Don't be funny. How many 80 pound bags will make 1 yard of concrete? I want a definitive answer this time.
