## How to calculate no of bricks, cement and sand for 1m3 brickwork

Calculating the required amount of bricks, cement, and sand for a brickwork project is a crucial step in the construction process. These materials are essential for creating strong and durable brick structures, and it is important to ensure that the right quantities are used to avoid any wastage or shortage. In this article, we will discuss how to calculate the number of bricks, cement and sand needed for 1m3 brickwork.

Before we begin, it is important to note that the calculations may vary depending on the brick size, mortar thickness and the type of bond used for the brickwork. In this example, we will assume a standard brick size of 230mm x 115mm x 75mm and a mortar thickness of 10mm.

Step 1: Determine the Volume of Brickwork

The first step is to calculate the volume of brickwork, which is the total space occupied by the bricks and the mortar. In this case, we are working with 1m3 (cubic meter) of brickwork.

Step 2: Calculate the Number of Bricks

To determine the number of bricks needed, we need to know the volume of one brick and the volume of the mortar joint. The volume of one brick can be calculated by multiplying its length, width and height, which gives us 230mm x 115mm x 75mm = 1,955,250 mm3.

Next, we need to subtract the volume of the mortar joint from the volume of one brick to get the actual volume of a brick. The volume of a standard mortar joint can be calculated as 10mm x 115mm x 75mm = 86,250 mm3.

Therefore, the actual volume of a brick is 1,955,250 mm3 – 86,250 mm3 = 1,869,000 mm3.

Now, to determine the number of bricks required for 1m3 of brickwork, we divide the volume of brickwork (1m3) by the actual volume of a brick (1,869,000 mm3).

Number of bricks = 1m3 ÷ 1,869,000 mm3 = 533.34 bricks.

This means that we need approximately 533 bricks for 1m3 of brickwork.

Step 3: Calculate the Volume of Cement

To determine the volume of cement needed, we first need to calculate the volume of mortar used in the brickwork. The volume of mortar can be calculated by multiplying the total volume of brickwork (1m3) by the ratio of mortar to brickwork. The standard ratio for mortar to brickwork is 1:4.

Therefore, the volume of mortar = 1m3 x 1/5 = 0.2m3.

Next, we need to convert the volume of mortar from cubic meters to cubic feet, which can be done by multiplying by 35.3147. This gives us 0.2m3 x 35.3147 = 7.06294 cubic feet.

Now, to determine the volume of cement needed, we need to know the volume of one bag of cement. A standard bag of cement weighs 50kg and has a volume of 0.035m3.

Using the weight to volume conversion, we can calculate the volume of cement needed as follows:

Volume of cement = (weight of cement ÷ density of cement) x volume of one bag of

## How to calculate no of bricks, cement and sand required for 1m3 brickwork

Brickwork is commonly used in construction for building walls, foundations, and other structures. It involves laying bricks in a specific pattern and bonding them together with mortar, a mixture of cement, sand, and water. Before starting any brickwork project, it is important to accurately calculate the required materials to avoid shortages or wastage. In this article, we will discuss how to calculate the number of bricks, cement, and sand required for 1m3 brickwork.

1. Determine the Size of Bricks: The first step is to determine the size of the bricks being used. Standard size bricks measure 8 inches by 4 inches by 2.25 inches (L x W x H). However, there are variations in sizes and shapes, so it is important to measure the actual size of the bricks being used.

2. Calculate the Volume of Bricks: The volume of bricks is calculated by multiplying the total number of bricks required by the volume of each brick. The volume of a standard brick can be calculated by multiplying its length by its width by its height. For example, if the required number of bricks is 500, the volume would be: 500 x 8 x 4 x 2.25 = 36000 cubic inches.

3. Convert Volume to Cubic Meters: The next step is to convert the volume of bricks from cubic inches to cubic meters. This is done by dividing the volume by 61023.7, as 1 cubic meter is equal to 61023.7 cubic inches. In our example, the volume of bricks in cubic meters would be: 36000 / 61023.7 = 0.59m3.

4. Determine the Ratio of Cement-Sand Mortar: The most commonly used ratio for cement-sand mortar in brickwork is 1:6, which means one part of cement is mixed with six parts of sand. This ratio is based on the volume of materials, so it is important to convert the volume of bricks into the volume of mortar.

5. Calculate the Volume of Mortar: To determine the volume of mortar, we need to multiply the volume of bricks (in cubic meters) by the ratio of cement-sand mortar. In our example, the volume of mortar is: 0.59m3 x 1/6 = 0.098m3.

6. Determine the Amount of Cement: The amount of cement needed for the mortar can be calculated by multiplying the volume of mortar by the ratio of cement in the mix (1/7 in this case). In our example, the amount of cement required would be: 0.098m3 x 1/7 = 0.014m3.

7. Determine the Amount of Sand: Similarly, we can calculate the amount of sand needed by multiplying the volume of mortar by the ratio of sand in the mix (6/7 in this case). In our example, the amount of sand required would be: 0.098m3 x 6/7 = 0.084m3.

8. Calculate the Number of Bricks: Finally, we can calculate the number of bricks required by dividing the volume of bricks (in cubic meters) by the volume of one brick (in cubic meters). In our example, the number of bricks needed is: 0.59m3 / 0.000445 = 1326 bricks.

In summary, to calculate the

## Mortar calculation in 1m3 brickwork

Mortar is an essential building material in brickwork construction, and its calculation is crucial in ensuring the correct mix of ingredients to achieve the desired strength and durability of the structure. In this article, we will discuss the process of mortar calculation in a 1m3 brickwork.

Mortar is a mixture of cement, sand, and water. The ratio of these ingredients determines the strength and consistency of the mortar. In general, the recommended mortar mix ratio for brickwork is 1:6, which means one part of cement is mixed with six parts of sand. However, the ratio may vary depending on the type of bricks, the climate, and the purpose of the structure.

To calculate the amount of mortar required for 1m3 of brickwork, we need to follow the following steps:

Step 1: Determine the volume of the brickwork

The volume of brickwork can be calculated by multiplying the length, width, and height of the structure. For example, if the length is 10m, width is 5m, and the height is 3m, the volume would be 10m x 5m x 3m = 150m3.

Step 2: Determine the volume of bricks used

The volume of bricks can be calculated by multiplying the total number of bricks with the volume of one brick. For example, if the size of a brick is 0.2m x 0.1m x 0.06m, the volume of one brick would be 0.2m x 0.1m x 0.06m = 0.0012m3. If we assume that 5000 bricks will be used in the construction, the total volume of bricks will be 5000 x 0.0012 = 6m3.

Step 3: Calculate the volume of mortar needed

The volume of mortar needed can be calculated by subtracting the volume of bricks used from the volume of the brickwork. In our example, the volume of mortar needed would be 150m3 – 6m3 = 144m3.

Step 4: Determine the amount of cement required

To calculate the amount of cement needed for the mortar, we need to know the mix ratio. As mentioned earlier, the recommended mix ratio for brickwork is 1:6. This means that for every 1 part of cement, we need 6 parts of sand. In our example, the volume of cement needed would be 144m3/7 = 20.57m3.

Step 5: Determine the amount of sand needed

To calculate the amount of sand needed, we use the same formula as for cement, but instead of dividing by 7, we divide by 1+6= 7. This means that the volume of sand needed would be 144m3/7 = 20.57m3.

Step 6: Add water to the mix

The amount of water required depends on the consistency of the mortar. It is usually recommended to use 16-20% of the total volume for water. In our example, it would be 144m3 x 20% = 28.8m3.

In conclusion, for 1m3 of brickwork, we would need 20.57m3 of cement, 20.57m3 of sand, and 28.8m3

## How much number of bricks are used in 1m3 brickwork

Brickwork is a common type of masonry construction that involves the use of bricks as building units. It is used for various purposes like building walls, arches, and other structural elements in buildings. The number of bricks used in 1m3 of brickwork depends on the size and type of bricks used as well as the type and thickness of the mortar joints.

The standard size of a brick used for construction purposes is 190mm (length) x 90mm (width) x 90mm (height). These dimensions are used to calculate the number of bricks required for 1m3 of brickwork. The volume of 1 brick is calculated by multiplying its length, width, and height, which equals 0.190m x 0.090m x 0.090m = 0.001539m3.

To calculate the number of bricks needed for 1m3 of brickwork, we need to divide the volume of 1m3 (1 cubic meter) by the volume of 1 brick (0.001539m3). This equals approximately 650 bricks. However, this number can vary depending on the types of bricks used.

For example, if standard bricks are used with a nominal joint thickness of 10mm, the number of bricks needed for 1m3 of brickwork will be higher due to the inclusion of mortar thickness. In this case, the calculated number of bricks needed might increase by 10% to 715 bricks.

On the other hand, if larger bricks are used with a nominal joint thickness of 10mm, the number of bricks needed for 1m3 of brickwork will decrease due to the larger size of the bricks. In this case, the calculated number of bricks needed might decrease by 10% to 585 bricks.

There are also other factors that can affect the number of bricks needed for 1m3 of brickwork, such as the type and thickness of the mortar used. A thicker mortar joint will require more bricks to fill the space, while a thinner mortar joint will require fewer bricks.

In summary, the number of bricks needed for 1m3 of brickwork can vary depending on the type, size, and thickness of the bricks, as well as the type and thickness of mortar used. Therefore, it is important to accurately calculate the number of bricks needed for a specific project to avoid any material wastage or shortage.

## Cement quantity required for 1m3 brickwork

The quantity of cement required for 1m3 brickwork varies depending on the size of the bricks and the type of mortar used. However, a general estimate can be made based on the standard design and construction practices.

Firstly, it should be noted that 1m3 of brickwork refers to one cubic meter of brick masonry, which is equivalent to 1000 bricks (assuming standard brick size of 230mm x 110mm x 76mm). The most commonly used mortar mix for brickwork is the 1:6 cement-sand mortar mix.

To calculate the quantity of cement required for 1m3 brickwork, the following steps can be followed:

Step 1: Determine the volume of cement mortar required

The volume of cement mortar can be determined by multiplying the area of brickwork by the thickness of the mortar joint. Assuming a standard thickness of 10mm for the mortar joint, the volume of cement mortar can be calculated as follows:

Volume of cement mortar = (Area of brickwork in m2 x Thickness of mortar joint in m)

Step 2: Calculate the dry volume of cement mortar

Dry volume is the volume of cement mortar after adding water to it. To calculate the dry volume, the following formula can be used:

Dry volume of cement mortar = (1+0.33) x Volume of cement mortar

Step 3: Determine the quantity of cement required

Based on the 1:6 cement-sand mortar mix and considering the dry volume of cement mortar, the quantity of cement required can be calculated using the following formula:

Quantity of cement = (Dry volume of cement mortar / Sum of ratios)

In this case, since the sum of ratios (1+6) is 7, the quantity of cement required will be one seventh of the dry volume of cement mortar.

Step 4: Convert the quantity of cement into bags

The quantity of cement is usually measured in bags (50kg per bag). Therefore, to determine the number of bags of cement required for 1m3 brickwork, the quantity of cement obtained from step 3 should be divided by the weight of one bag of cement (50kg).

For example, if the dry volume of cement mortar is calculated to be 0.015m3, then the quantity of cement required will be 0.00214m3 (0.015/7). Since 1m3 of cement is equal to 1000 liters, the quantity of cement required will be approximately 2.14 liters. This can be converted into bags by dividing it by the weight of one bag (50kgs), which is equal to 4.28 bags (2.14/50).

In conclusion, for 1m3 brickwork using the 1:6 cement-sand mortar mix, approximately 2.14 liters or 4.28 bags of cement will be required. However, it is always recommended to consult with a structural engineer or architect for a more accurate estimation as different factors such as brick size, type of mortar, and climate conditions can affect the quantity of cement required.

## Sand quantity required for 1 cubic metre brickwork

Sand is an essential component in the construction industry and is used in various applications such as brickwork, plastering, and concrete. In brickwork, sand is used as a binding agent to hold the bricks together and create a strong and durable structure. The quantity of sand required for 1 cubic metre of brickwork depends on various factors such as the type of bricks and the thickness of the mortar joints.

The type of bricks used in brickwork can be clay bricks or fly ash bricks. Clay bricks are commonly used and have a standard size of 190 mm x 90 mm x 90 mm. Fly ash bricks, on the other hand, have a size of 230 mm x 110 mm x 75 mm. The thickness of the mortar joints also varies depending on the type of bricks used.

To calculate the sand quantity required for 1 cubic metre of brickwork, we need to consider the volume of bricks and the volume of mortar used.

1. Volume of bricks: The volume of one standard clay brick is 190 mm x 90 mm x 90 mm = 0.001539 m^3. The volume of one fly ash brick is 230 mm x 110 mm x 75 mm = 0.00153 m^3. As 1 cubic metre is equal to 1000 litres, the number of bricks required for 1 cubic metre of brickwork is:

– For clay bricks: 1000/0.001539 = 650 bricks

– For fly ash bricks: 1000/0.00153 = 654 bricks

2. Volume of mortar: The thickness of the mortar joint varies from 10 mm to 12 mm. We will consider a 10 mm thick mortar joint in this calculation. The volume of mortar used for 1 cubic metre of brickwork is:

– For clay bricks: 650 x 0.01 = 6.5 m^3

– For fly ash bricks: 654 x 0.01 = 6.54 m^3

3. Volume of sand: The ratio of sand to mortar is typically 1:6 in brickwork. This means for every 6 parts of mortar, we need 1 part of sand. So, the volume of sand required for 1 cubic metre of brickwork is:

– For clay bricks: 6.5 m^3/6 = 1.08 m^3

– For fly ash bricks: 6.54 m^3/6 = 1.09 m^3

Hence, the quantity of sand required for 1 cubic metre of brickwork is approximately 1.08 m^3 for clay bricks and 1.09 m^3 for fly ash bricks. It is essential to note that this calculation is an estimation, and the actual quantity of sand required may vary depending on the quality and moisture content of the sand, and the skill of the mason.

In conclusion, sand plays a critical role in brickwork and is required in a considerable quantity. Civil engineers must ensure that the appropriate amount of sand is used to achieve a strong and durable brick structure. Accurate calculations and proper supervision can ensure the right amount of sand is used, reducing construction costs and avoiding wastage.
