Answer #1:
9 cubic yards cement weight nearly 1260 lbs
=============================
Answer #2:
Answer #1 is a very intriguing one. It says that 9 cubic yards (9 x 27 cubic feet)
of cement weighs nearly 1,260 pounds. If so, then each cubic foot would weigh
nearly 5.2 pounds, which corresponds to nearly 8.3% of the density of water.
So cement would float quite high in water. Mysteriously, it doesn't.
I found one online conversion reference that says that
1 cubic foot of Portland cement weighs 94.02 pounds.
(94.02 pounds/cubic foot) x (9 cubic yards) x (27 cubic foot/cubic yard) = 22,847 pounds(rounded)
Somehow, that sounds more like it.
Also, if the question actually meant 'concrete, limestone with Portland cement"
instead of 'cement', then the weight is nearly 60% greater than that.
1201 Kg
13.785 ounces
6 tons
Type your answer here... 250,000 cubic yards
The density of limestone varies from something on the order of 110 pounds per cubic foot (a shade over 1 ounce per cubic inch) to over 160 pounds per cubic foot (about 1.5 ounces per cubic inch).
400kg or there abouts
20' by 26' by 5" requires at least 10 cubic yards of cement.
Three and one-quarter million cubic yards. There are 4,360,000 cubic yards of concrete in the dam
If you pour to a 4" depth, you will need at least 24.89 cubic yards. If you use a 6" depth, you will need at least 37.33 cubic yards.
A minimum of 1.23 cubic yards at 4" thick.
3 cubic feet or about one-tenth of a cubic yard. Cement is generally quantified in yards or cubic yards. It takes 27 cubic feet (3x3x3) to make a cubic yard. Therefore 3 cubic feet is about .111 or about one-tenth of a cubic yard (3 divided by 27).
It depends on what it consists of. It could vary greatly.
To cast 41 cubic yards of concrete, you typically use a mix ratio of 1 part cement, 2 parts sand, and 3 parts gravel (aggregate). For 41 yards of concrete, you'll need approximately 6.8 cubic yards of cement, 13.6 cubic yards of sand, and 20.4 cubic yards of gravel. Adjust the mix based on specific project requirements or concrete strength needed. Always consider adding water based on the moisture content of the materials and desired workability.
To figure out consider this: a dumpster that can enclose 30 cubic yards would have the dimensions approximately of :6feet tall, 22 feet by length and 8 feet wide
13 1/3 cubic yards
Assuming you use the standard 4" depth, you will need at least 1.75 cubic yards.
The amount of rebar depends on the thickness of what you are making. All three dimensions.
