Quantity Of Cement And Sand Calculation In Mortar CFT

A quantity of cement mortar is required for a building or structure to analyze the rate of brickwork and plaster or to estimate the masonry work. Cement mortar is used in different proportions,  i.e. 1:1, 1:2, 1:3, 1:4, 1:6, 1:8 etc.

Calculation Of Quantity Of Cement Mortar In Brickwork And Plaster:

Let's assume that the volume of masonry work is 20cft. and we assume the ratio of mortar 1:4.

When we estimate the mortar quantity for any masonry work, we just get the wet volume of mortar.

Now we will see how to calculate the dry volume of mortar and then we will calculate the cement and sand quantity in 20cft.

Grains of sand in dry conditions include air voids. Therefore, by adding water to the dry sand, the sand volume will be reduced This happens because of the presence of air voids in particles of sand. The percentage of air void sand compressibility is between 20% and 27%. 

Normally, when converting the wet volume into the dry volume, we take the highest percentage of air void compressibility of sand. That's 27% of it. 

So when we calculate the dry volume of mortar, we just multiply the wet volume by 1.27.

Dry volume= 20 x 1.27 = 25.4 cft

So now we have the dry volume of mortar which is 25.4 Cft

Now we will calculate the quantity of sand and cement in 25.4 Cft. 

first, we will calculate the sum of ratio and our mixing RATIO IS 1:4.

Sum of ratio= 1+4= 5

The volume of cement will be calculated as:

(1 ÷ 5) x 25.4 = 5.08 cft

Since the volume of 1 bag of cement is 1.25 Cft, so the number of a bag of cement will be calculated as:

5.08 ÷ 1.25 = 4.064 bags

The volume of Sand will be calculated as:

(4 ÷ 5) x 25.4 = 20.32 cft

Quantity of cement in 20 Cft  masonry mortar = 4.064 Bags say 4.5 or 5 bags

Quantity of cement in 20 Cft  masonry mortar = 20.32 cft

Conclusion 

To calculate the dry mortar volume, you simply need to estimate your work item's wet mortar volume and then multiply it by 1.27.

Once you get the required dry mortar volume the amount of cement and sand required for the mortar can be calculated based on the proportion of the mixture.

Types of Masonry Construction Based on Material

A variety of materials may be used in masonry construction, combined with mortar of varying strength. Brick, stones cement, veneer, gabion, etc. are some of the common materials used.
Some of the important masonry construction based on the material used are briefly explained.

1. Brick Masonry Construction

The construction of brick masonry uses first-class burnt clay bricks. Third-class bricks are used in masonry for less important construction. Second-class bricks are best for plastered masonry construction due to lack of finish compared to first-class bricks. 

The overall tensile strength of the brick masonry is lower, regardless of the brick class chosen. Overall performance depends on the size, position, and number of openings provided to the structure of the masonry.

2. Stone Masonry Construction

Stone, relative to any other, is the most durable solid, and weather-resistant construction material. These are less affected by wear and tear from day today. Masonry structures made of stone also last longer. It has a lifetime of between 300 and 1000 years plus years. It is widely used in masonry construction because it is numerous advantageous.

Stonemasonry has two main classifications:

1. Rubble Masonry
2. Ashlar Masonry

Rubble Masonry is again classified into:

• Uncoursed or Coursed Random Rubble Masonry
• Uncoursed or Coursed Square Masonry
• Polygonal Rubble Masonry
• Dry Rubble Masonry

Ashlar masonry is again classified into:

• Ashlar Fine Masonry
• Ashlar Block in Course
• Ashlar Chamfered Masonry
• Ashlar Rough Tooled Masonry
• Rock or Quarry Faced Masonry

3. Concrete Masonry Construction

In the construction of concrete masonry, the blocks of concrete are pressed on top of others similar to the construction of brick masonry. This produces a turbulent formation The scale of concrete blocks is smaller than that of bricks, so it takes less time to lay concrete blocks.

It is, therefore, popular to build concrete blocks as it is affordable and gain high fire resistance. The concrete blocks of masonery come in different sizes, forms, and special designs, making it a flexible medium for building. It is commonly used in factories, universities, and residential building construction.

4. Veneer Masonry Construction

This construction of masonry is a style that is mainly used for remodeling and interior finishing. It gives the appearance of a more economical and isolated stone or brick wall. It is possible to place veneer maçonnery units on the existing concrete wall, giving a better look.

5. Gabion Masonry Construction

Gabions are baskets made of zin-protected steel or galvanized steel, filled with broken stones of medium size. These gabions are working as one unit. This functions as preservation or as retention of walls. These units of masonry are in nature well-drained and flexible. As a result, they have high horizontal pressure resistance such as water floes, surface flow, frost damage and floods. Commonly used gabions are in fact rectangular. The strength of gabions relies on the steel's corrosion resistance properties used in gabion baskets.

6. Composite Masonry Construction

Two or more types of building materials are used for the construction of a composite masonry structure. These masonry buildings are used to increase the building's appearance and to make use of available material resources with the utmost economy.

What is Civil Engineering

Engineering:

The use of science and math is engineering to model or construct things and buildings etc. People are called engineers who do engineering.

Civil engineering:

Civil engineering is the word for infrastructure design and construction work. Usually, it means large buildings such as bridges, reservoirs, homes, and tunnels. It also covers complicated networks such as networks for water, irrigation, and sewerage. It also involves building homes and dwellings.

Branches of civil engineering:

Civil Engineering has enormous scope and includes a wide range of sub-disciplines. Within this branch of engineering, there are different fields you can choose to pursue your career. The following are the branches of civil engineering.

1. Construction engineering:

Deals with planning, construction, and maintenance of structures such as houses, schools, plaza, bridges, and dams, etc.

2. Structural engineering:

Deals with Structural Analysis and Design of structures such as Framework of structures and design of structures to withstand environmental stresses and pressures and to remain secure, stable and secure during their use.

3. Geotechnical engineering:

Importance and Applications of civil engineering (in short)

With time, civil engineers are becoming increasingly important. They are now also responsible for the fire control systems and the installation of rapid-fire exit points in the buildings these construct. This will help minimize the loss of life in accidents involving fire. One of the oldest engineering professions is civil engineering. Classical structures such as the building of the Egyptian pyramids and the Roman road systems are based on principles of civil engineering. Environmental engineering is another very important aspect of civil engineering. In this case, civil engineers are concerned with different methods of purifying contaminated air, water, and soil. It is necessary to clean the polluted system, remove the waste and return the purified constituent to the natural system.
Civil engineers are also responsible for the design of high-quality transport systems such as roads, airports, bridges, marine ports, etc. A structural engineer must decide the best design of these structures and will look after the building process so that after completion the stability of these structures is guaranteed. These structures should also be satisfied for the public.
