What is a Block Wall Calculator & What is its Purpose in Construction?

Are you constructing a block wall? Do you need help in estimating the number of blocks you need? If yes, the block wall calculator can provide you with ultimate help. The calculator is a useful thing that is mostly used in construction projects.

Block Wall and the Use of a Calculator 

A block wall is a type of wall that is built using large blocks similar to bricks. The main difference is that bricks are small and not very strong, while a block is much stronger and durable because it is built using concrete. These blocks are also called CMU’s which means Concrete Masonry Units. Sometimes these are also known as concrete blocks or cement blocks. However, no need to get puzzled here because all these mean the same thing. Blocks are strong and heavy load-bearing structures. A concrete block wall is built by stacking the blocks in a row, one by one, and joining them together with mortar. Such walls are usually built for boundaries, basements, and for supporting any structure. The blocks are available in standard size, which is 16 x 8 x 8 inches.  Its usage is quite common in construction because it makes the construction process easy and fast. Now, when we talk about the usage of the block wall calculator, it is clear that it is an online tool that gives you an estimate of the number of blocks, and some also tell you about the mortar volume needed to build the wall.  The concrete block calculator is simple to use. It requires some data related to the wall and block from you, and gives the estimate to you in an easy way. The requirements of every calculator differ from one another. However, most of the calculators are used in the following way: 

• Measure the total length of the wall yourself or have it measured by the experts. 
• Note down the measurement in feet or meters or the units demanded by the calculator. 
• Enter the dimensions in the calculator with the correct unit.
• Add the wall’s height in the same unit. This helps the calculator find the total wall area.
• Choose the size of the concrete block. This feature is different in every calculator. Some require the block’s height and weight separately, some require the block size, and some calculate the standard size block for estimation or let you enter custom dimensions.
• Some calculators also ask for the wall thickness, especially if you are calculating volume or mortar needs.
• Enter all the data in the calculator and calculate the estimate. 

The result displayed is different by every calculator. Most calculators give a thorough estimate of the number of blocks needed of the required size. Some also highlight the use of mortar, the volume or the bags of mortar required, and some give an overview of the sand required. Along with this, most calculators also highlight the cost estimate. The calculator that gives cost estimation also asks to add the price per block. You can also expect to get a material estimate and the cost for each material.  No matter what calculator you are using and what way it works, in the end, every calculator will provide you with an estimate of the number of blocks you will need for building a concrete block wall. 

Working of an Online Concrete Block Wall Calculator

The concrete block calculator has a built-in formula through which it calculates and provides an estimated result. Its formula divides the total wall area by the area of one block. Here is the formula through which it works.  Number of Blocks = Block Area / Wall Area The block area refers to the surface area of one concrete block. It is the face of the block that becomes part of the wall. It is calculated by multiplying the length and height of a single block. On the other hand, the wall area is the total surface area of the wall you plan to build. It is found by multiplying the length and height of the entire wall. There are also calculators available online that include extra elements to provide a more accurate estimate, along with the cost. These include mortar thickness, the volume of mortar, and block spacing. Sometimes it also includes block spacing for thorough estimation. When you enter your wall’s measurements, the calculator first finds the total wall area. Then it divides this area by the surface area of a single block. The result is the number of blocks required for the entire wall. In addition, some calculators also show the estimate of the volume of mortar needed to fill the gaps between blocks. They do this by calculating the difference between the total wall volume and the combined volume of all blocks. A few tools include cost calculations if you enter the price per block or price per bag of mortar. This automated process gives quick and correct results and removes the need for manual calculation and effort, and removes the need to guess the estimate. This tool is best for builders and contractors, but homeowners also get equal benefit if they use the tool and avoid buying excess materials.

Purpose of Using a Block Wall Calculator

The main purpose of using a block wall calculator is clear. As we can understand from its name, it is used to calculate the concrete blocks.  Its main usage is finding the estimate before starting the construction process. It is useful because it saves time and prevents buying extra material, which is later wasted. The use of a calculator also aids in buying the exact material, not less or more. Its purpose also highlights the project planning and budgeting. This makes it useful for both professional builders and homeowners who want to plan their projects efficiently without hurdles and carry on smoothly. It takes only a few seconds to enter your wall dimensions, and the calculator instantly provides accurate results. In short, the purpose of this calculator is to make wall construction easier, faster, and more accurate without causing any delay due to material shortage or making it late due to manual calculation and estimation.

Advantages of Using a Block Wall Calculator

The advantages are several. Using a block wall calculator is the best option as compared to manual calculations. We know it makes our work easier and smarter. Other than this, highlighted below are more benefits you can avail by using the calculator.

You Get an Accurate Estimate Without Errors 

The calculator has a built-in formula that it uses to automatically perform the calculations for you and saves your time. It saves you from performing manual calculations and conversions, which could give many errors, and sometimes takes a lot of time to give results. This removes the chances of human error and gives precise results within seconds. It minimizes calculation mistakes that often happen when done by hand.

It Helps in Material and Cost Planning

As highlighted above, there are calculators that not only estimate the number of blocks but can also provide the approximate amount of mortar and the total expense that it will cost you. This in a result, it helps in better budgeting and material planning before the work begins.

It Prevents the Wastage of Blocks and Mortar

When you use the calculator, you get an accurate estimate, which guarantees you buy the right amount of materials. This prevents over-ordering or running short of blocks during construction.

Useful for Both Small and Large Projects

The calculator is a good option for both small and large scale projects. It shows the correct result for all types and sizes of walls you want to build.
