Imperial Questions How many bags of concrete do I need for a 10×10 slab 2 inches thick?Ī 10×10 slab that is 2 inches thick requires 57 40-lb bags, 38 60-lb bags, or 29 80-lb bags. The Ultimate Concrete Calculator (Cubic Meters, Cubic Yards, & Bags). You can also calculate both the volume and the number of concrete bags for various applications with the following engineering calculator: Note: It is important to use constant units in your calculations. The yield of concrete bags is estimated as shown in the following table.īy using this table, you can easily calculate the number of premixed concrete sacks you need for a specified volume. Step 2: Dividing the required calculated volume in step 1 by the yield

To know more about how to calculate the volume of concrete for various applications and shapes, you can read the following article, “ Calculating Yards of Concrete: Explained“. In brief, you should divide these shapes into two or more regular shapes to simplify your volume calculations. In addition to the aforementioned regular shapes, irregular shapes also often exist in many concrete applications. Or, if you are calculating cubic meters of concrete, you should convert all the units from centimeters and millimeters to meters. Each 3 feet convert to one yard, and each 36 inches convert to one yard. For example, if you are calculating concrete yardage, you should convert all units from feet and inches to yards. It is important to note that the units should be consistent. The following table shows the volume formulas for different shapes. For example, the formula of determining the volume of a rectangular prism is simply length multiplied by width multiplied by thickness. In fact, its formula largely depends on the shape of the element.

The first step is to determine the volume of concrete. Step 1: Calculating the volume of concrete With this easy method, the yield is often assumed, unless tested or mentioned in the product’s specifications.īesides, it is important to note that our engineering tools and calculators, specifically the concrete volume and bag calculators, are integrated with more advanced methods for high accuracy and precision.

Step 2: Divide the required volume by the yield of the concrete bag.

Step 1: Calculate the required volume of concrete.

One of the simplest methods is summarized in the following two steps: There are several ways to estimate how many pre-blended sacks you need for any application. These applications include post holes, overlays, repairs, and small steps, patios, walkways, ramps, and others.īut how can i calculate how many bags of do i need for my project? The easy formula for calculating how many concrete bags you need for any application Please make sure to ask a specialist if you are unsure.It is often easier and more economic in small applications to use bags of concrete instead of ready mix concrete. For example, how deep should you dig your holes for setting posts? There is no simple answer as there are so many factors that can affect the depth the hole needs to be the soil type and the planned load on the post are just two factors. Please note: When planning your project, you may need to seek specialist advice. This way, you will know exactly how many bags of cement you will need for your project, whether you’re rendering a wall, setting a post or paving your driveway. The calculator will perform the sums for you - where relevant it will add a small percentage for the wastage that inevitably happens when mixing & using cement-based products, and then it will round the result up to the nearest whole 20kg bag. For each calculation you will have to know the dimensions of your object. You can calculate how much concrete, cement, sand, mortar or render you will need.
