How many yards of concrete do i need for a 10x10 slab

The amount you will need for a 10 x 10 slab is 1.3 cubic yards, we always add an extra 10% to allow for any slab depth variations or spills that may occur.

Similarly, How much does it cost for 10 yards of concrete? Concrete Cost Per Yard

With concrete delivery and pouring, most pay $119 to $147 per cubic yard depending on the PSI of the cement. A full 10-yard truckload with delivery costs $1,169 to $1,444, which is enough to pour a 20×24 driveway.

How much area does a 40 lb bag of concrete cover? Regarding this, how much does a 40 lb bag concrete cover, as 133 lb concrete = 1 CF, so a bag of 40 lb concrete = 40/133 = 0.30 CF, therefore, a 40 lb bag concrete approximately cover around 1.8 square feet area upto depth of 3 inch.

How many bags of concrete do i need for a 10 x 10 slab? Your measurement methods will change depending on the shape of your future concrete slab. For example, you’ll mark a rectangular shape using length and width. A circular shape needs that you find the diameter.

Once you get the dimensions of your slab, enter them into the calculator along with the thickness. Access your project area measurements formed to the nearest foot. If you’d somewhat do the math yourself, simply measure length, width and height in feet. Then multiply these dimensions together. Divide the resulting number by 27 to find the cubic yardage.

To determine the amount of concrete you require for a slab, you should obtain the cubic yardage of the area you will be filling. Just understand these steps:

• Measure the area in feet.
• Multiply the length by width, and then by thickness.
• Divide the resulting number by 27 to find cubic yards.

The volume of concrete required for a 10- by 10-foot slab depends on the diameter of the slab. For a 4-inch slab, either eight 60-pound or six 80-pound bags are required, while for a 6-inch slab, either 12 60-pound or nine 80-pound bags are necessary.

Before placing a concrete slab, the local construction department should be reached to determine whether any limitations exist or if a permit is required for construction. When it’s time to build, preparing the site by levelling it and creating strong and level forms for the project ensure that the slab is correctly laid.

How to Calculate Concrete

Concrete, which is a mix of water, aggregate, and cement, is most commonly sold by the cubic yard, but is also available in pre-mixed bags.

It’s important to calculate the amount of material needed as accurately as possible since you often only get one chance for the pour. So, how much concrete will you need?

We’ll cover the process for estimating concrete in detail below, but you can also use the calculator above to simplify the process.

Steps to Calculate Cubic Yards of Concrete

• Measure the length, width, and height of the slab, footing, or column.

  If the area is complex or multiple pours are needed, break the project into smaller pieces and calculate the concrete needed for each individually.

  For instance, when measuring a slab that is not a simple rectangle, try breaking it into different sections and measure the yards needed for each section separately.

  

• Convert dimensions to feet if they aren’t already. Conversion calculators make it easy to convert inches, yards, or meters to feet.
• Multiply the width times the length times the height (W × L × H), or use our volume calculator to find the cubic feet.
• Convert the volume to cubic yards from cubic feet. To do so, divide the cubic footage by 27 to get the yards of concrete needed.[1]
• Round up to the nearest yard as most suppliers will likely not sell fractions of a yard. It is worth asking your supplier if they will sell a partial yard of material, but most do not.

• Estimate how many pre-mixed bags are needed for smaller projects when it isn’t practical to order a truckload of concrete.

  The table below shows the coverage of different sizes of pre-mix bags. On average, it will take 90 40lb bags, 60 60lb bags, or 45 80lb bags to fill one cubic yard of concrete.

• Add 5%-10% additional material to account for settling, spillage, and waste.[2] This will ensure you can complete your project in a single pour without needing to order a short load, pay crew overtime, and risk a cold joint that all can occur if you come up short.

How Much is a Yard of Concrete?

One cubic yard is equal to the volume of a cube with edges that are one yard (three feet) in length.

You might be wondering just how much concrete is in a cubic yard? A cubic yard is equal to 27 cubic feet or 46,656 cubic inches, or 45 80lb bags.

Concrete Cubic Yards Formulas

Use the following formulas to calculate the concrete needed for various types of pours.

Square and Rectangular Areas

The volume for a rectangular space is equal to the length times the width times the height. For slabs, substitute the thickness for the height measurement.

volume = width × length × height

yds3 = width ft × length ft × height ft / 27

Circular and Cylindrical Areas

The volume for a circular space is equal to pi times the radius squared times the height. The radius is equal to the diameter divided by two.

volume = π × radius2 × height

yds3 = π × radius ft × radius ft × height ft / 27

π = 3.14159265359

Steps

Divide the steps into rectangles, then find the volume for each rectangle/cube. Add the volume for each rectangle to find the total volume.

volume = width × length × height
yds3 = width ft × length ft × height ft / 27

How Many Bags of Concrete do you Need?

So far, we’ve covered how to calculate yards, but if your project is small, you can use pre-mixed bags of concrete. Pre-mixed bags are sold by companies like Quikrete or Sakrete, and come in 40-pound, 60-pound, or 80-pound sizes.

Using bags can be easier than ready-mix when you have many small pours or a small project where a truck is not practical or cost-effective. But, keep in mind that mixing bags on-site can become difficult if you’re pouring a large slab or many footings.

For the most part, ready-mix concrete from a truck is more cost-effective than bags and makes sense if you have a mid-size project and can pour all at once.

So, how many bags of concrete do you need?

Calculating bags is a little less straightforward since each bag size will fill different volumes. Use the calculator above to estimate how many bags you’ll need.

The table below shows the average fill in yards for various pre-mix bag sizes. Check the bag you’re using to find the exact fill-rate for the product.

How to Calculate Concrete Costs

The cost of a concrete project varies depending on the project’s size and scope, your geographic location, and the type of material used.

Concrete Cost per Yard

Ready-mix concrete typically starts around $115 per yard but could cost upwards of $150 or more, depending on the mix and your location. Consider that there will likely be additional fees for ready-mix for smaller projects, such as delivery or short-load fees.[3]

Cost per Bag

Pre-mix bags usually range from $2.50 to $7, making them a cost-effective choice for small projects.

The average cost to install a concrete slab is $6 – $20 per square foot. Besides the cost of concrete and materials, there are also labor costs for preparing the area, the pour, and finishing.

A standard brush finish will likely be on the low end of the price range, while a decorative finish with coloring will be on the high end of the range. Consider getting a professional concrete installation estimate from contractors in your area for a more accurate cost estimate.

Tips for Preparing for a Ready-Mix Concrete Pour

Much of the work to pour concrete is done before the truck even arrives at the project. You’ll need to measure and lay out the site and install forms to create the edges of a slab or contain a footing.

Plan a proper base using a gravel or stone calculator to estimate the right amount of base fill.

Use rebar or fiber/steel mesh to reinforce the concrete and to prevent cracking in the future. Use our rebar material and reinforcing mesh calculators to estimate the amount of reinforcement needed for your project.

Ensure the installation team is ready for the installation and able to begin as soon as the truck arrives to avoid having it set up before the project can be completed and minimize idle time.
