Sonotube Calculator

Use the sonotube calculator to determine the quantity and the cost of the concrete you will need when building round columns.

What Is A Sonotube?

This is a cylindrical shape column made of multiple layers of quality spiral-wound fiber glued together. They are used to give a round form to the concrete. They are manufactured by “Sonoco”.  

How To Calculate Concrete And Cost For Sonotubes?

Go through the below-mentioned steps to calculate the Concrete:

For Premixed Concrete:

• Firstly, calculate the volume of the sonotube by using the cylinder volume formula
• After that find the equivalent weight of the column with the help of the density
• Find the number of bags, diving the weight by (bag size x (1-waste)
• Multiply the number of bags with the cost of each bag
• To find the cost of concrete per unit volume, divide the material cost by the volume of sonotube
• Find the cost per column by multiplying the cost of concrete per unit volume with the volume

For Mixing My Own Concrete:

• Find the volume of the sonotube
• Use density to calculate the weight of the column
• Choose the concrete mix ratio as per your need 
• Find the total volume (Volume x (1+ waste)
• Calculate the volume of cement, sand, and gravel according to their ratio
• Calculate the material cost of cement, sand, and gravel by multiplying their volumes with the cost
• Find the total cost by adding the cost of all the materials

Practical Example:

Suppose you have a sonotube that is 120 inches high and has a diameter of 16 inches.  The density that you need is 6 cu ft, the concrete bag size is 10 kg and the cost of each bag is 10 RS, waste is 5%. 

Find: 

• How much concrete for sonotube you will need?
• Now How Many Bags of Concrete Do I Need for Sonotube?
• The cost of concrete

Solution:

Given that:

Density = 6 cu ft

Sonotube Size = D = 16 inches

Radius = D / 2 = 16 / 2 = 8 

Height = 120 inches

Volume of Sonotube = πr^2h = 3.14159265 x (8)^2 x 120 = 24,127 cu in

Convert it into Cu ft by multiplying with 0.000578704

Volume of Sonotube = 24,127 x 0.000578704 = 13.963

For Premixed Concrete Bags:

Density = Mass / Volume 

6 = Mass / 13.963 

Weight = 6 x 13.963 = 83.78 lb

Convert the weight into kg  multiply the weight by 0.453592

Weight = 83.78 x 0.453592 = 38 Kg

Bag Size = 10 kg

Waste = 5 % = 5 / 100 = 0.05

Now How Many Bags of Concrete Do I Need for Sonotube?

Number of Bags = Weight / Bag Size x (1-waste)

Bags Needed = 38 / 10  x (1-0.05)

Bags Needed = 38 / 10 x 0.95 = 38 / 9.5 

Bags Needed = 4 

Now calculate the Material Cost:

Material Cost = cost of each bag x No of bags 

Material Cost = 10 x 4 = 40 RS 

Cost of concrete per unit volume = Material Cost / Volume 

Cost of concrete per unit volume = 40 / 13.963 = 2.86 Rs

Cost Per Column = Cost of concrete per unit volume x Volume 

Cost Per Column = 2.86 x 13.963 = 39.93418 Rs

For Mix My Own Concrete:

Given that:

Waste = 5%

Price of Cement = 5 Rs

Price of Sand = 6 Rs

The  Price of Gravel  = 7 Rs

Concrete Mix Ratio = 1:5:10 

Volume = 13.963 

Total Volume = 13.963 x (1+ 0.05)

Total Volume = 13.963 x 1.05 = 14.66 cu ft

Volume of Cement = Total Volume x (Ratio of Cement / Sonotube Size)

Volume of Cement = 14.66 x (1 / 16) = 14.66 x 0.0625 = 0.91625

Cost of Cement = 5 x Volume = 5 x 0.91625 = 4.58125 Rs

Volume of Sand = Total Volume x (Ratio of Sand / Sonotube Size)

Volume of Sand = 14.66 x (5 / 16) = 14.66 x 0.3125 = 4.58125

Cost of Sand = 6 x Volume = 6 x 4.58125 = 27.4875 Rs

Volume of Gravel = Total Volume x (Ratio of Gravel / Sonotube Size)

Volume of Gravel = 14.66 x (10 / 16) = 14.66 x 0.625 = 9.1625

Cost of Gravel = 7 x Volume = 7 x 9.1625 = 64.1375 Rs

Total Cost = Cost of Cement + Cost of Sand + Cost of Gravel

Total Cost = 4.58125 + 27.4875 + 64.1375

Total Cost = 96.20625 Rs
