How to calculate bricks in 4 inch wall per sq.ft

Calculating the number of bricks required for a 4 inch wall per sq.ft is an essential task in the construction process. Bricks are commonly used as a building material due to their strength, durability, and affordability. As a civil engineer, it is crucial to accurately determine the number of bricks needed to estimate the project’s cost and ensure a proper construction schedule.

Here is a step-by-step guide on how to calculate the number of bricks in a 4 inch wall per sq.ft:

Step 1: Determine the Size of the Wall

The first step is to determine the size of the wall, which will give you the total area in square feet that needs to be covered by bricks. Measure the length and height of the wall in feet and multiply them to get the total square footage.

For example, if the wall is 10 feet long and 8 feet high, the area will be 80 sq.ft.

Step 2: Calculate the Brick Size

Bricks come in various shapes and sizes, and each type has a different dimension. For this calculation, we will consider the standard size of a brick – 8 inches by 4 inches by 2 inches (L x W x H).

Step 3: Convert Brick Size to Feet

To make it easier to calculate the number of bricks required per sq.ft, we need to convert the brick size from inches to feet. We will divide each dimension by 12 as 12 inches is equal to 1 foot.

So, our brick size will be 0.66 feet by 0.33 feet by 0.16 feet.

Step 4: Determine the Number of Bricks per Sq.ft

We can now determine the number of bricks needed per sq.ft by dividing the total area of the wall (obtained in step 1) by the brick size in square feet. This will give us the number of bricks required per row.

In our example, the number of bricks per row will be:

(Number of feet in length x Number of feet in height) / Brick size in sq.ft = (10 feet x 8 feet) / (0.66 feet x 0.33 feet) = 10.61 bricks per row

Step 5: Calculate the Number of Bricks for the Entire Wall

To get the total number of bricks for the entire wall, we need to multiply the number of bricks per row by the total number of rows. The total number of rows can be calculated by dividing the height of the wall by the height of one brick.

In our example, the total number of rows will be:

Height of the wall / Height of one brick = 8 feet / 0.16 feet = 50 rows

So, the total number of bricks for the entire wall will be:

(Number of bricks per row) x (Total number of rows) = 10.61 x 50 = 530.5 or approximately 531 bricks.

Step 6: Account for Wastage

It is essential to account for wastage while calculating the number of bricks needed for a wall. A general rule of thumb is to add an extra 5% to the total number of bricks calculated in step 5 to account for any cuts, damaged bricks, or human error.

So, for our example, the final number of bricks required will be:

531 x 1.05 = 557.55 or approximately 558 bricks.

What is thickness of cement mortar

What is thickness of cement mortar

Cement mortar is a type of building material used in masonry construction that is made by mixing cement, sand, and water. It is commonly used for brickwork, plastering, and pointing in walls, floors, and ceilings. The thickness of cement mortar refers to the measurement of its horizontal, vertical, or diagonal depth on a surface.

The thickness of cement mortar is crucial in determining its strength and durability. Generally, the thicker the mortar, the stronger the structure; however, the thickness should not exceed a certain limit to avoid cracking. The appropriate thickness of cement mortar depends on several factors, including the type of structure, the type of bricks or blocks used, and the purpose of the structure.

For instance, in brick or block masonry walls, the recommended thickness of cement mortar is usually between 10-12 mm for a single brick or block wall and 20-25 mm for a double brick or block wall. This thickness is sufficient to provide a strong and stable bond between the bricks or blocks while also allowing for any slight irregularities in their shape and size.

In plastering and pointing, the thickness of cement mortar is comparatively thinner, typically between 6-10 mm. This is because these applications require a smoother and more level finish. Additionally, a thinner layer of mortar helps to reduce the weight and cost of the structure.

The thickness of cement mortar also varies depending on the type of bricks or blocks used. For example, in walls made with lightweight blocks, the thickness of cement mortar is usually around 10 mm, while for walls made with dense concrete blocks, the thickness can be up to 12 mm. This is because denser blocks are heavier and require a stronger bond.

The purpose of the structure is also a determining factor in choosing the thickness of cement mortar. For load-bearing structures, such as foundations and retaining walls, the thickness of mortar should be around 20 mm or more. This provides better structural stability and prevents cracks from forming under heavy loads. On the other hand, non-load bearing structures, such as partitions and non-structural walls, may require thinner mortar layers of 6-10 mm.

Calculation for mortar quantity:

Step 1: Calculate the volume of the wall (length x height x width):
Volume = 10m x 3m x 230mm (wall thickness) = 6.9m3

Step 2: Calculate the volume of mortar required (20-30% of wall volume):
Mortar volume = 6.9m3 x 0.25 (25% allowance) = 1.725m3

Step 3: Convert mortar volume to bags:
1m3 of mortar requires approximately 100 bags of cement (depending on density and type of mortar used).
Therefore, 1.725m3 = 172.5 bags of cement.

In conclusion, for a 9 inch brick wall, 1,842 bricks and 172.5 bags of cement are required for an area of 30m2.
