Dec 01, 2019· I calculated that I need 21 bags of concrete per fence post - this seems a lot to me! Could someone double-check my calculations? Hole area: 0.25 m2 (0.5 m x 0.5 m) Post area: 0.01 m2 (0.1 m x 0.1 m) Hole depth: 0.9 m Volume = 0.216 m3 (0.25m - 0.01m x 0.9m) Each concrete bag fills 0.01 m3 in volume
Apr 20, 2017· You'll need a bit more than one 1 ton bags of ballast and around 6 bags of cement I reckon. A 1 ton bag is actually around 900Kg ish, so probably 40-45 bags at 25kg each is my guess. 1:4 ratio is quite strong, 1:6 would be fine - 12 shovels of ballast to 1/2 bag of cement.
18 S.F. x 2 Inches thick or 1/6 Ft. = 3 C.F. This equals to 3 x 0.6 = 2 bags of 80# concrete NOT 14 bags. I have 40 S.F. by 3 inch thick (1/4 Ft) area to be filled with concrete, which will take 6 bags of concrete. If I'm wrong in my figures, please let me know. Thanks, Floyd Smith frsmith31@gmail or .

How much building sand and cement do i need to lay 100 standard concrete blocks on flat (retaining garden walls) with 10mm bed assuming a 5:1 mortar mix? Thanks for the reply RJH, Would that be about 600kg of sand + 120kg (5 bags) Portland cement then?
You'll need to use the weight of one bag of cement to calibrate your "part" measurements. For instance, if you're using 80-pound bags of cement, one "part" equals 80 pounds. Thus, for a standard mix using 80-pound bags, you'll need 40 pounds of water (80 x 1/2 = 40), 160 pounds of dry sand (80 x 2 = 160) and 80 pounds of crushed stone aggregate.

Now that you used the concrete calculator to estimate how much concrete you need for your project, you should decide if you need a ready-mix concrete or a bagged solution. The truth is, larger jobs such as driveways are often easier to complete when ordering concrete by the yard instead of mixing it bag after bag manually.
Essentially you are solving for volume and then converting to cubic yards. For concrete, the formula for volume is as follows: length x width x thickness. To determine how many bags of concrete you will need, divide the total cubic yards needed by the yield. Use the following yields per each bag size: 40 pound bag yields .011 cubic yards
Mix two 50lb bags of concrete with water in a mixing tub or 5-gallon bucket. Add concrete into the hole and around the 4" x 4". Depending on your climate, let concrete set up for 24 - 48 hours.

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 Bag Concrete Yield The following table shows the approximate yield of mixed concrete for common bag weights.
Density of concrete = 2400 kg/cum. So, 1 bag of cement produces = 400/2400 = 0.167 cum. No. of bags required for 01 cum of concrete = 1/0.167 = 5.98 bags ~ 6 bags. From above, if the concrete mix is 1:2:4, to get a cubic meter of concrete we require. 1.Cement = 6 bags = 300 kgs. 2.Fine Aggregate = 115/0.167 = 689 kg
