Calculating Using Concrete Services

Concrete services are professional and reliable services to fit your requirements regarding the concrete for your structures. Moreover, there are many concrete contractors available to complete the job for you. You can always try yourself but you might face issues such as imperfect calculations causing wastage. For small projects, you can try the DIY way, but for large structures and more concrete use, it is suggested to use concrete services. Additionally, there are many concrete estimating services to offer you accurate concrete calculations.

Volume Formula for Concrete Calculations

Construction structures are often in geometrical shapes. They consist of slabs, footings, and columns. Moreover, they have space that they occupy which is called volume. This volume requires concrete to fill and form reliable structures. To understand volume, we need to take a box of length (1m), breadth (1m), and depth (1m) and fill it with concrete. This will yield a volume of concrete equal to 1-meter cube (1m3).

Volume formula= Length x Breadth x Depth = 1m x 1m x 1m = 1m3

To fill this box of 1m3 volume, you need 25KN of concrete.

 

Tip: Remember that 1KN of concrete equals 100 Kgs and the density of concrete is 25 KN/m3.

 

To avoid any misunderstanding, always keep in mind that volume calculation is 3 dimensional (3D). This means our formula will be in 3 dimensions which will multiply to yield the volume.

Volume Formula: L x B x D

For objects in the structure resembling a cylinder, you can use the following formula:

Volume Formula (Cylinder) : Surface Area (Length x Breadth) x Depth (Depth is the third dimension)

Concrete Calculation Step By Step

Concrete material companies as well as concrete businesses use the number obtained from calculation. Therefore, it is necessary that you know about concrete calculations. Below is a step-by-step formula and technique for calculating the concrete porings for space:

Step I:

Measure the length and width of the space or structure where you will pour the concrete. Now multiply both numbers to get the total area.

Moreover, there are different formulas to calculate the volume for different structures and geometrical shapes and such as:

Concrete Slabs = Area of Rectangle x Depth

Concrete for Columns:

(Rectangle) = L x B x H

(Circular) = Surface Area x Height of Column

Rectangular Beams = L x B x H

Step II:

Obtain the square footage by multiplying the length by the width. Furthermore, concrete services use this square footage to pour the material into the structure. Moreover, for a 10 feet long and 5 feet-wide driveway, you will require 50 square feet area to cover.

Step III:

Next, measure all the sides for any structure that is not rectangular or square. Additionally, it can be an irregularly shaped object but they are important to cover.

Step IV:

Afterwards, using a graph paper, draw the area with proper scaling and dimensions.

Step V:

Now break the drawing into different geometrical shapes such as triangles, rectangles, or squares.

Step VI:

You will also need to determine the area of each of the geometrical shapes. Square and rectangle area is simply length times width. On the other hand, the triangle area is the base time height, and then divide the result by 2.

 

 

Step VII:

Furthermore, find the total area by adding each area you obtained in the previous steps.

Step VIII:

Next, determine the thickness and convert the results into proper units. For instance, you want any part of the structure to be 5 inches thick then divide 5 by 12 to convert it into square feet. You will get 0.416.

Step IX:

For concrete services, you need to measure and identify the units and requirements properly. Moreover, in this step, multiply your area by the thickness to get the volume of concrete in cubic feet. Next, multiply 50 by 0.416 to get 20.8 cubic feet of concrete.

Step X:

Concrete services measure the concrete quantity in cubic yards. Therefore, you can convert your volume measurement result into cubic yards by dividing it by 27. It will be 20.8/27= 0.77 cubic yards of quality concrete.

Step XI:

Finally, you will need to sort out the number of bags. The concrete services use the following formula to determine the quantity:

Number of Bags: Total Volume in Cubic Yards / Yield

Where yield is:

0.011 Cubic yards for a 40-pound bag

0.017 Cubic yards for a 60-pound bag

0.022 Cubic yards for the 80-pound bag

 

Tip: There are several online calculators available for calculations. Using them you can get details and calculate the results without any hard calculations.

FAQs

How do I calculate how much concrete I need for my floor?

To cover your floor space with concrete pourings, you can use the formula length x breadth x thickness. Additionally, to convert units from cubic feet to cubic yards, simply divide the number by 27.

How do you calculate CFT?

It is volume obtained using the formula LxBxH. CFT is known as the volume of a cube with each side measuring 1 foot (0.3048m). It is an imperial and US unit.

How much concrete do I need per square foot?

It depends upon the structure and geometrical shape of the structure. Moreover, you can obtain an area per square foot and multiply it with the thickness you require to get cubic feet of volume.

What is the formula for calculating the floor?

The formula for calculating the floor is Length (foot) x Width (foot). This will yield an area in square footage.

What is a simple calculation for concrete?

A simple calculation for concrete is by measuring the length, width, and height of the space you want to fill with concrete. Afterward, plug the values in the volume formula to obtain the volume.
