Feb 09, 2011· A rule of thumb for concrete, 2000lbs per yard, would give you. 2000 / 27 cuft/yd = 74.1 lb / cuft That makes it about 1cuft is 80lbs, with all the variations in mix (cement, flyash, sand, rock, and water ratios) the exact number could vary widely.
In general 150 pond per cubic foot (+- 4000 lb per cubic yard) is roughly what you a lot of folks would say a c.y. of concrete weighs. It's not exact because it varies based on the density of the aggregates used and how much water is still in it, and the aggregate is the largest part of the mixture.
Thus, a 3,600-pound cubic yard contains about 800 pounds of cement, which comes out to 10 of the 80-pound bags of cement or 13.3 of the 60-pound bags. Pure cement, sand and crushed rock all have about the same density, so a block of pure cement measuring 1 cubic yard of volume (about 3,600 pounds) will contain 45 bags of cement.
An 80-pound bag of concrete yields 0.60 cubic feet of wet concrete when mixed with the proper amount of water. Concrete consists of portland cement, sand, stone, gravel and additives that make the substance cure when it dries.
This gives you 1.6 cubic feet. If you forget the 1728 it is simply 12” x 12” x 12” or the number of cubic inches in a cubic foot. So now that we know the volume the second step is to calculate how many bags of concrete it will take to fill the hole. On the bag it will tell you how many cubic feet the bag will fill. This is the “yield”.

Choose your volume units (e.g. cubic feet) Enter the volume (V) The calculator returns the number of 60 lb bags needed to mix that much concrete.
The tables below give you estimates for the number of 50- or 60-lb bags you need for concrete slabs of various sizes. Remember: Before beginning any excavation, call 811 to check for underground utilities.
Oct 24, 2008· the question is "how many cubic feet" of Portland (Type 1) in a 92 lb bag. I found two different numbers on the internet. One says Portland weighs 1506 kg/m3 (cubic meter), which converts to 93.85 lbs/cft, so a 92 lb bag is right at 1 cft of Portland.
QUIKRETE® CONCRETE MIXES CALCULATOR: Enter the size of the slab you want to build in square feet. The calculator will indicate the number of 60 or 80 pound bags of QUIKRETE® Concrete Mix you need to build a 4″ or a 6″ slab.
Most concrete suppliers will not sell fractions of a yard of concrete, though it is worth asking about. So, in this example, you would want to buy bags. Using the table below, you would need to buy at least eight 80 lb. bags and one 40 lb. bag (yielding a total of 5.1 cubic feet) of concrete to allow enough for extra.
Pre-mix concrete comes in bags that are 60 lbs. and 80 lbs. A 60 lb. bag provides 0.45 cubic feet of cured concrete. A 80 lb. bag provides 0.6 cubic feet of cured concrete. If you have concrete delivered it is sold by the yard (which is a cubic yard = 27 cubic feet).

The Concrete Calculator can be used to estimate the volume and weight of the concrete you will need for the size, or area, of the land that needs to be covered. When purchasing, we suggest that you buy a little more than the calculated result.
Calculating the amount of concrete you want for your project can be a very confusing project. Pre-mix cement comes in 60 lb. and 80 lb. Bags. A 60 lb. bag of cement supplies 0.45 cubic foot of cured concrete and an 80 lb. bag of cement provides 0.6 cubic feet of cured concrete.
For example, the yield on an 80-pound bag of Sakrete, which is premixed cement, sand and gravel, is about 0.6 cubic feet. To work out how many bags you need, divide the volume of your project by the yield. For example, if your volume is 1.3, you divide 1.3 by 0.6. The answer is 2.2 bags.
There is 2/3 cu. ft. per 80 lb. bag of pre-mixed concrete. It takes 133 pounds of quikrete to make 1 cubic foot, so... - there is 0.6 cubic feet (80/133) in one 80 pound bag, and it takes one and two-thirds 80 pound bags of quikrete to make 1 cubic ft (133/80 = 1.66).
There are 0.6 cubic feet in an 80lb bag of concrete and 0.45 CF in a 60 lb bag. So take the total volume of concrete needed and divide by 0.6 or 0.45 depending on which size bag is to be used. Its really not all that difficult for example.
