How many bags of concrete do i need? Let me clear first, here we are discussing about ready mix concrete mix bags. Traditionally, concrete is made by mixing cement, sand, and aggregate together to make the homogeneous dry mix. Then water is added to the mix to make concrete for different work. Show
 But now people don’t want to order each material separately and then mix them and use them for work. The concrete is now available in dry mix products which are filled in bags like cement bags. So, the buyer only needs to add sufficient water to make wet concrete. There is a various brand that supplies this dry mix concrete product such as Quikrete, Sakrete, and other brands in the USA. How many bags of concrete in yards are required to depend on the weight or size of the concrete dry mix bag you have ordered from the company.

2. SancreteThe original bagged concrete mix, trusted by pros since 1936. This professional-grade mix delivers consistent performance, high strength, and a smooth finish that makes it ideal for every concrete project from slabs to footings and everything in between. A quality mixture of sand, coarse aggregate, and cementitious materials. For repair and building jobs where concrete thickness exceeds 2 inches (50 mm). Ideal for pouring footings, setting posts and poles, and building walkways, driveways, patios, and steps. When used as directed, SAKRETE High Strength Concrete Mix meets or exceeds the strength specifications in ASTM C 387. Use these free concrete calculators to estimate how much concrete you'll need for slabs, footings or columns. It is a good idea to overestimate the amount of concrete needed so you won't come up short on the jobsite. CONCRETE CALCULATOR FORMULAWhat equation should I use to find out how much concrete I need?How to calculate concrete:
Here’s what the math looks like for a 10’ by 10’ concrete patio:
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:
READY MIX VS. BAGGED CONCRETEShould I order concrete by the yard from a ready mix company or just use bags?Larger jobs such as driveways are easier to complete when ordering concrete by the yard, rather than trying to mix bag after bag by hand. For smaller jobs, like a walkway, modest patio or footings, you should calculate the number of concrete bags instead. Bagged concrete is ideal for:
If you’re purchasing bagged concrete you may be able to have it delivered, but if it is only a few bags you’ll be responsible for transporting it yourself. You’ll also need additional equipment for mixing the concrete. A rented mixer can be very helpful, but a wheelbarrow works for just a few bags. Ready mixed concrete by the yard is good for:
If you’re planning to order concrete from a ready mix supplier, they’ll need to know how many yards of concrete to deliver. Many ready mix companies will have a minimum order of 1 yard, and will charge shortage fees when ordering partial batches. The average truck holds between 9 and 11 yards total. If your project requires more concrete, multiple trucks will be necessary. How much does concrete weigh?Concrete is usually ordered in cubic yards, but if you're looking for concrete weight it varies depending on the type of mix being used. However, most ready mix suppliers estimate that a cubic yard of concrete weighs about 4,000 lbs. So if you need three yards, that would be around 12,000 lbs (3yds x 4,000lbs). Ask your supplier if you'd like to know the exact weight. CONCRETE ESTIMATING TIPS
Calculating the amount of concrete needed for slabs (including odd shapes)Rule of thumb: add 1/4" to the thickness of your slab for your slab concrete budget. This assumes you have the job evenly graded to the right depth, and the grade is well compacted. If you check your grade and one spot is 4", some spots are 4.5" to 5"-the best solution for both the job quality and your concrete budget is to fix the grade. Odd shapes: Transform odd shapes into rectangles and odd shapes are suddenly easy to figure. Figure driveway 14' x 20' and your estimate will be good. Here is why: The driveway is 16' at the top and 12' at the bottom. Through the center the width averages 14'. Calculating the amount of concrete needed for footingsFootings will rarely follow the drawing exactly. In rocky soil the footings may collapse when big rocks are excavated This was supposed to be a 12"*12" footing, but note how the left side of the footing has collapsed. Calculate the true width. The excavator may have dug too deep, or it may have rained and footings needed to be dug out deeper to reach firm soil. So it is important to check a variety of spots on your footing and get an average size. Then use the calculator to figure the amount of concrete needed. House slabs on grade that are 8" out of grade with a 4" slab also have some of the footing above the grade too. This 12" x 12" footing needs to be calculated 12" x 16" so the footing is figured to go above grade to reach the 4" slab thickness. Estimating concrete stepsSteps seem tricky to calculate but are not. If there are three steps leading up to a porch:
Here is an example: This porch has 9 sq. feet of porch surface, so enter in the slab calculator 4" thickness by 3' width by 3' length. This totals .11 cubic yards. The porch also has 9 linear feet of 6" step. So enter in the footing calculator, 6" depth by 12" width (always figure steps with a 12" width) by 9' length. This totals .17 cubic yards. The total concrete needed for the 3' by 3' porch will be .28 cubic yards. (.11 + .17 cubic yards = .28 cubic yards) Repeat this for added layers of steps. 3' x 3' Porch Calculating the amount of base fillUsing a Margin of Safety: Problems Caused by Underestimating the Amount of Concrete Never try to order the exact amount of needed concrete. Include a margin of safety. A perfectly placed order of concrete will finish the job with a small amount left over. A 20 cubic yard order with 1 cubic yard left over is a good order. A 20 cubic yard order that comes up cubic yard short is not a good order. Extra costs of coming up short of concrete
Three steps to ordering enough concrete:
Rule of thumb for margin of safety:
It can be upsetting to end up with any extra concrete. You are having to pay for this concrete after all. However, realize you are doing your job a service by ordering enough concrete - which means you are going to have a little concrete left. Requesting your ready mix supplier to visit your siteAfter you have chosen a Ready Mix Supplier, have a representative come to your site to give his/her opinion on the quantity required. Compare the figure with what you came up with. Discuss any variances with the supplier. Your ready mix supplier is invaluable for checking your view of job conditions, checking your margin of safety, identifying issues you may not have thought of, and informing you of any local conditions you need to be aware of. How many 60 pound bags of cement make a yard?60 Bags of 60 lb concrete make a yard or concrete. 45 Bags of 80 lb concrete make a yard or concrete.
How many bags of 60 lb quikrete are in a yard?Generally, there are 60 bags of 60lb concrete in a cubic yard. A cubic yard of concrete weighs around 3600 pounds, so, number of 60 lb bags of concrete in a cubic yard = 3600÷60 = 60 bags. Thus, you will need 60 bags of 60lb concrete to make one cubic yard.
