5 or 6. An 80 lb. bag of ready mix concrete will make about 1/2 cubic foot of concrete. A 94 lb. bag of portland cement mixed with 1 1/2 cu. ft of stone (coarse gravel) and 1 cu. ft. of sand will make 3 cubic feet of concrete or 6 times as much. (this is a common 1:2:3 mix) Quikcrete ready mix is often made with 1 part cement, and 2 1/2 parts each sand and stone. A 1:1 1/2: 3 mix is a stronger mix but you get less volume, at 5 1/2 cubic feet per bag of cement.

Oh, absolutely! Just like every tree in our painting has its own unique shape and beauty, a mixed number can have zero as the numerator. It's like having a blank canvas ready for your creativity to flow. Embrace the zero and let your imagination create something wonderful on this mathematical canvas.
Ready mixed concrete is a pre-prepared version of the building material concrete. It is available from firms such as Concrete2You, Rapid Ready Mix and ReadyMix2Go.
In the United States, if you are buying concrete mixed up and ready to pour, it is typically sold by the cubic yard (3ft x 3ft x 3ft) volume. But they usually call this just a 'yard' of concrete, knowing that it is a cubic yard.
Ready mix concrete is usually delivered by a concrete mixer, once delivered it is ready to use immediately. One cubic meter will cost around USD $160.

I cant accuratly help you with the cement content but you need about 1 ton of sand and 1 ton of stone for every cubic meter of concrete. The cement content would depend on what you are using the concrete for. At 15 newtons of strength you would ( and this is just an educated guess) need about 95kg of OPC cement, 85kg of GGBS slag, 1.5lt of WRA (water reducing agent) and about 70lt of water to gain a 50mm slump per cubic meter. If I were you I would get it ready mixed. 70 Cube is a LOT of cocrete. Ready mixed 15 Newton concrete is about £75 inc vat per meter delivered. Regards Colin, a Tarmac concrete batcher.
Each 60 pounds bag of ready mix concrete will make .45 cubic foot of concrete. There are 27 cubic feet in a cubic yard. You will need 60 bags of 60 pound premixed concrete to make 1 cubic yard.
It is typically measures in cubic yards. Anything over 2 cubic yards is a lot of mixing, so you'd likely want to order that from a concrete company in a ready mix concrete truck.

Mortar has sand in it. Concrete has cement, sand and stone.
A person may be able to purchase an concrete truck at a ready-mix company that can be ordered, or added along with, the amount of concrete that a person or company is providing. For example, the general rule is that a concrete truck will, about average, hold ten cubic yards. Again, this is average because some trucks will actually hold about eight cubic yards to about nine cubic yards.
Every 80lb concrete bag should be mixed with 4 quarts or 3.7 liters of water. This mixture will allow you to place aproximately .60cu/ft of concrete. There are 27 cu/ft in a cu/yd. The number then becomes .0222 yards per 80lb bag. Therefore 45 bags of 80lb (4000 psi) concrete ready mix will be enough for 1 yard of concrete.
Ready-mixed concrete producers in North America numbered more than 2,700 in 2002. A total of 13 U.S. concrete contracts secured more than $1 billion in sales in 2002
