## Cement mortar calculation for 10m3 brickwork

Cement mortar is a mixture of cement, sand, and water used to bind bricks or stones in construction work. It is an essential material in brickwork, as it provides strength and stability to the structure. Therefore, it is crucial to properly calculate the amount of cement mortar required for a specific amount of brickwork.

In this example, we will calculate the cement mortar required for 10m3 of brickwork. Before starting the calculation, it is important to know the following things:

1. The standard ratio of cement mortar for brickwork is 1:6 (one part cement to six parts sand).

2. The density of cement is 1440 kg/m3.

3. The density of sand is 1600 kg/m3.

4. The volume of 1 bag of cement is 0.0347 m3.

5. The volume of 1 cubic meter of brickwork is 1m3.

Now, let’s follow the steps to calculate the cement mortar required for 10m3 brickwork:

Step 1: Determine the volume of the mortar

The volume of cement mortar required for brickwork is calculated by multiplying the area of brickwork and the thickness of mortar.

The area of brickwork = 10m3.

The thickness of mortar = 12mm (0.012m).

Therefore, the volume of mortar required = 10m3 x 0.012m = 0.12m3.

Step 2: Calculate the dry volume of mortar

The dry volume of mortar is calculated by considering the shrinkage and wastage of cement during mixing and transportation. It is calculated by applying a factor of 1.33 to the wet volume of the mortar.

Dry volume of mortar = 0.12m3 x 1.33 = 0.16m3.

Step 3: Determine the materials required for 1m3 of mortar

As per the standard ratio of 1:6, 1m3 of mortar requires 1 part of cement and 6 parts of sand.

Therefore, the materials required for 1m3 of mortar are:

Cement = 1/7 x 0.16m3 = 0.022m3.

Sand = 6/7 x 0.16m3 = 0.138m3.

Step 4: Convert the volume of materials into weight

To convert the volume of materials into weight, we need to multiply their volume with their respective density.

Weight of cement = 0.022m3 x 1440 kg/m3 = 31.68 kg.

Weight of sand = 0.138m3 x 1600 kg/m3 = 220.8 kg.

Step 5: Calculate the number of bags of cement required

The weight of one bag of cement is 50 kg. Therefore, the number of bags of cement required = 31.68 kg/50 kg ≈ 0.63 bags.

Since, we cannot use 0.63 bags of cement, we will round it up to one bag.

Therefore, for 10m3 brickwork, we will need 1 bag of cement and 220.8 kg of sand.

In conclusion, for 10m3 of brickwork, we will require 1 bag of cement and 220.8 kg of sand to make a 12mm thick cement mortar in the ratio of 1:

Step 2: Calculate the volume of mortar

The volume of mortar can be calculated by multiplying the volume of brickwork by the proportion of mortar required. In this case, the volume of brickwork is 10m3, and the proportion of mortar is 1:4. So, the volume of mortar will be:

10m3 x 1/4 = 2.5m3

Step 3: Calculate the quantity of cement

To calculate the amount of cement needed, we need to convert the volume of mortar into the weight of cement. The weight of one bag of cement is 50kg. Therefore, the weight of 2.5m3 of mortar will be:

2.5m3 x 1440 kg/m3 = 3600 kg

Hence, for 10m3 of brickwork, we need 3600 kg of cement.

Step 4: Calculate the quantity of sand

To determine the amount of sand required, we will use the same method as for cement. The weight of one cubic meter of sand is approximately 1450kg. So, the weight of 2.5m3 of mortar will be:

2.5m3 x 1450 kg/m3 = 3625 kg

Therefore, for 10m3 of brickwork, we need 3625 kg of sand.

Step 5: Calculate the quantity of water

The amount of water required for brickwork is calculated based on the water-cement ratio. The commonly used water-cement ratio for brickwork is 0.4. Hence, the weight of water needed will be:

0.4 x 3600 kg = 1440 kg

Therefore, for 10m3 of brickwork, we need 1440 kg of water.

Note: It is essential to maintain the correct water-cement ratio to ensure the strength and durability of the brickwork.

In conclusion, the quantity of materials needed for 10m3 of brickwork with a 1:4 proportion of cement and sand will be 3600 kg of cement, 3625 kg of sand, and 1440 kg of water. It is crucial to accurately calculate the materials to avoid any wastage and ensure the structural integrity of the brickwork. You can adjust the calculation as per the specific requirements and proportions for different types of bricks and mortar joints.

## What is cement mortar ratio for brickwork

Cement mortar is a mixture of cement, sand, and water used as a bonding agent in brickwork, masonry, and plastering construction projects. The ratio of these components plays a crucial role in determining the strength and durability of the mortar.

The cement mortar ratio for brickwork is usually expressed in terms of the proportions of cement and sand in the mix. For example, a ratio of 1:4 means that for every 1 unit of cement, 4 units of sand are used. The water content in the mix is not included in the ratio but needs to be adjusted to achieve the desired consistency.

The recommended cement mortar ratio for brickwork is 1:6, meaning one part of cement to six parts of sand by volume. This ratio is suitable for general brickwork and provides a good balance between strength, workability, and durability.

However, the ratio may vary depending on the type of brickwork and the availability of materials. For example, for lightweight bricks, the ratio may be increased to 1:8 to achieve sufficient bonding strength. Similarly, for thicker joints, a ratio of 1:3 may be used to ensure proper filling and better bonding.

The use of a higher proportion of cement in the mix increases the strength and durability of the mortar, but it also leads to a decrease in workability. On the other hand, using a higher proportion of sand increases workability but may result in weaker mortar.

Other factors that may influence the cement mortar ratio for brickwork include the climate conditions, type of mortar, and the type of bricks used. In hot and dry climate conditions, the ratio may be adjusted to 1:5 to prevent the mortar from drying out too quickly. Similarly, for stronger mortar, additives such as lime or pozzolanic materials may be added in addition to cement and sand.

It is essential to maintain the correct proportion of cement and sand in the mortar mix to achieve optimum strength and durability. Deviating from the recommended ratios may result in a weaker or more brittle mortar, leading to cracks and other damage in the brickwork over time.

In conclusion, the cement mortar ratio for brickwork is usually 1:6, but it can be adjusted depending on the specific requirements of the project. It is crucial to consult a structural engineer or follow the specifications provided by the building codes to ensure the correct proportion is used for the brickwork.
