## Concrete blocks needed: determining the type

There are two main types of concrete blocks: pure concrete and cinder blocks. The first kind can be both solid or feature a hole on each side or a few cavities to reduce its weight and cost. Concrete blocks provide a good basis for concrete block construction. The second kind consists of cement, sand, concrete, and coal ash are called cinder blocks. The latter is a lighter and less dense type which is approximately 1,5% cheaper than concrete blocks.

In order to know how many blocks you need overall, you need to decide which kind you are going to use first: a cinder block calculator, a concrete block calculator, or maybe a cement wall calculator. After that is done, you can proceed to the process of estimation.

### Construction projects using concrete blocks

## Concrete block calculator: step-by-step

Now, when you know what To calculate concrete blocks and the materials needed, we need to approach the construction process step-by-step.

### 1. Determine the dimensions of a building

You must determine the dimensions of the building to understand the number of blocks needed. This is the first step of an overall block count process. Knowing the size of the building and the scope of work, the contractor can understand the approximate total number of bricks that he and his team will need.

### 2. Choose the block size

The most commonly used block size is 8 x 8 x 4 inches long and 8 x 8 inches wide. The thickness of your block is NOT crucial when determining the total number of masonry blocks you need, but is vital for the estimate of the quantity. The typical thicknesses are 4′′, 7′′, 8′′, 10′′, 12′′ or 14′′. The nominal size is the actual block size and includes a mortar joint of 3/8′′.

### 3. Calculate the number of blocks

In this paragraph, we will determine how many cement blocks are needed to build a regular apartment wall. Let’s say that the wall that we are constructing is 10 ft wide x 50 ft high. Its total area is 10 * 50 = 500 ft. If using 16″ x 8″ blocks, the area of every single block is 128 square inches. Divide it by 144 and you will get the area it covers — 0.89 sq. ft. Multiply both numbers and get the number of concrete blocks needed: 500 x 0.80 = 445.

### 4. Estimate mortar for a block wall

Calculation of mortar required on the joints on the concrete block walls depends upon the mortar used. Cement needs 3 bags per 100 blocks on average. To understand the number of bags needed, divide the number of blocks by 333.3. Standard mortar is a 1:3 mixture of cement with sand; that’s about 4.4 pounds for one bag. You can buy pre-mixed bags of mortar, which typically contain around 12 portions of mortar for a 220.5-pound container. Use our calculator if you need to add mortar bags.

### 5. Count the insulation blocks

Insulation is necessary for pretty much every building that has both exterior and interior spaces. To count the insulated area, simply measure the height and the width of the wall and subtract them to know the total dimensions of your wall.

### 6. Know the tools needed to install a concrete block wall

The installation of concrete blocks requires special equipment and a number of tools, and every professional builder has a wall building masonry toolset. This is what it usually includes:

- Wheelbarrow
- Nylon string
- Spirit level
- Brick jointer
- Shovel
- Trowel
- Club hammer
- Bolster

## Frequently Asked Questions

A typical cement block size is 16 x 8 inches and covers the area of 0.89 feet (16″ x 8″ = 128″/144 = 0.89 ft). Multiply it on your wall size in square feet and get the number of blocks: 0.89 x 300 = 267.

### How many blocks do I need per square foot?

The rule of thumb for the concrete wall is 1.1/8 blocks / square foot.
