Figure about 1/2 cubic foot per 60 lb bag. The basic formula is to use equal amounts of cement, sand, and gravel. There are 27 cubic yards per cubic foot. It depends upon how thick you are planning to pour the concrete. For one foot thick, you would need 9 cubic feet of concrete. For 6" thick, you would need 4 1/2 cubic feet. I'll give you the answers for 1 ft thick and for 6" thick. For 1 foot thick, you need 9 cubic feet at 1/2 cubic foot per 60 lb bag equals 18-60 lb bags. That's six 60 lb bags of concrete, plus six 60 lb bags of sand, plus 360 lbs of gravel. For 6 inches thick, divide each of these by 2 to give 3-60 lb bags of concrete, 3-60 lb bags of sand, plus 180 lbs of gravel.
7 bags cement
This depends on the size of gravel, the water content of the gravel, and the material composition of the rock used to make the gravel. Typically 1 cu.yd. of gravel wieghs 3000 lb.
Clay w/fire is brick - - - Concrete + Brick = Brick House Water + Cement = Concrete Clay + Limestone = Cement Stone + Cockleshell = Limestone
Concrete actually contains cement as well as sand and gravel. We say "cement concrete" because cement is an ingredient in concrete. And because the cement is what binds together the sand and gravel that make up the concrete.
Concrete.
Concrete is what you make a sidewalk from. To make concrete, you mix Portland cement, sand, gravel (aggregate) and water. The cement holds the aggregate together.
Forty five 80 pound bags of cement are needed to make one cubic yard of concrete.
just get a gravel, sand, and cement and then mix it with a little amount of water.
A concrete mixture of sand, cement, and small gravel is used to make the concrete from which the tubular concrete pipe is made. The pipe is made of concrete.
Both glass and concrete contain sand. Sand is melted to make glass. It is mixed with aggregate (gravel) portland cement and water to make concrete.

Concrete is measured in metric volume via cubic yards. Standards consider a 94 lb. bag of cement to be one cubic foot when freshly packed. 94 evenly fits into the 1-2-3 mix ratio when figuring the recipe 1 part cement- 2 parts gravel- 3 parts sand to make concrete.
Well, you make a sidewalk from concrete, not just cement. Concrete consists of cement, sand, gravel and water. You will need 5.5 cubic feet of concrete. A standard sidewalk grade of concrete would be 1 part cement, 2 parts sand, 3 parts gravel- so the sidewalk needs 0.91 cu ft of cement- about 87 pounds worth- plus sand and gravel. If you want to buy the premixed bags of concrete (like Sacrete), you will need about 17 of the 40 pounds bags. And you did not ask, but 3 inches is kind of skinny- I would go for at least a 4 inch thick sidewalk.
5,000,000 barrels of cement were used to make the 4,300,000 cubic yards of concrete required.
