Yes using a specific set of algorithms.
Concrete is made from cement. This normally comes in 20 kg bags. So the answer is kilograms. A kilogram is roughly 2.2 pounds.
The weight of a concrete 80 lb bag is 80 pounds.
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.
NO!
Most bags will make a 1/3 of a cubic foot of concrete.
The concrete slump test is used to measure an aspect of concrete. This test is used to measure the workable of concrete as well as its freshness and health.
For M10 (1:3:6) Grade of concrete cement bag consumed = 4.4 bags/cum M15(1:2:4) Grade of concrete cement bag consumed = 6.6 bag/cum M20(1:1.5:3) Grade of concrete cement bag consumed = 8.2 bag/cum
Typically, one bag of concrete requires about 2.5 to 3 quarts of water for proper mixing.
The word bag is a singular, common, concrete noun. The word bag is also a verb (bag, bags, bagging, bagged).
An 80-pound bag of premixed cement = .667 cubic feet, or 2/3 of a cubic foot, of concrete. A 60-pound bag of premixed cement = .5 cubic feet, or 1/2 of a cubic foot, of concrete.
To determine how many bags of concrete you need for three slabs, you'll first need to calculate the total volume of concrete required for all slabs. Measure each slab's length, width, and thickness, then use the formula: Volume = Length × Width × Thickness. Divide the total volume by the yield of a single bag of concrete (usually around 0.5 cubic feet for a 60-pound bag) to find out how many bags you need.
Usually concrete mix comes in 40, 60 or 80 pound bags.
