With a sledgehammer.
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.
Usually concrete mix comes in 40, 60 or 80 pound bags.
Concrete strength is measured by "bag mix", meaning that the bag mix answers the question, how many bags of cement per yard of concrete. If you're looking for a "6 bag" mix, that means 6 bags of cement per yard of concrete. A "bag" of cement is 1 cubic foot. A yard of concrete is 27 cubic feet (3 X 3 X 3 = 27). If you want to make a "6 bag mix" of concrete, using 1 bag of cement, you would make 1/6 yard concrete with 1 bag of cement. If you would be content with a "5 bag mix", you could make 1/5 yard. Concrete is often defined as ratios of cement,sand,aggregate such as: 1:2:3 which is a very common mix. For a 1:2:3 mix you would need 1/6th of the volume to be cement. The dry ingredients are generally 1.6 x finished concrete volume. Therefore dry volumen for 1 cubic yard = 1.6 cu yards = 43.2 cu ft. 1/6 x 43.2 = 7.2cu ft. Therefore, if one bag is 1 cu ft we need 7.2 bags for a healthy 1:2:3 mix. A '6 bag mix' or a '5 bag mix' are a bit short on cement.
there is 5 shovels full in a 25kg bag of cement
The answer is, remarkably, 6. Answer: "6 sack" or "6 bag mix" has six bags of cement per cubic yard of concrete mix. Since each sack/bag contains 94 lbs of dry cement, this equals 564 lbs of cement per cubic yard of concrete.
it takes 45 Bags of 80# mix to make a cubic yard
Usually 1 cubic foot. It can be sold in smaller bags, but when someone refers to the ratio of cement in a concrete mix (i.e. a "5 bag mix") then they mean 1 cubic foot.

you wouldn't even need 1 bag of cement and there are also lots of variables, thickness, mix ratio, bag sizes?
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.
No. If it's hard in the bag it must have gotten moisture in it which caused it to cure. It will make a handy doorstop though.
Lean mix concrete is used for substructures like foundations,piles,etc.,Ready mix concrete is used for superstructures and also for mass construction.Generally, quality of ready mix concrete is good when compared to the lean mix concrete.Workability of lean mix concrete is high when compared to RMC.
