Different types of bricks used in masonry works are:-
- Common Burnt Clay Bricks
- Sand Lime Bricks
- Engineering Bricks
- Concrete Bricks
- Fly ash Bricks
Bricks are used as siding within the construction industry due to its vital characteristics and simply because it will be a decent cheap choice. Below I tend to summarize the advantages and applications of the foremost ordinarily used varieties of bricks.
Common Burnt Clay Bricks
Common Burnt Clay Bricks are first in the list of different types of bricks. Common Burnt Clay Bricks are shaped by pressing in molds. Then these bricks are dried in a hot kiln.
Common Burnt Clay Bricks are employed in general work with no special enticing appearances. Once these bricks are employed in walls, they need covering or rendering.
Common Burnt Clay Bricks are classified into different types such as:-
- Class 1
- Class 2
- Class 3
Let us understand what we mean by the class 1, class 2 and class 3 Bricks.
Class 1 Common Burnt Clay Bricks
These are the finest quality of common burnt clay bricks available in the market. Its cost is highest among the three. Class 1 Bricks are the ideal burnt bricks.
Some of the features of Class 1 Bricks are:-
- Table-Moulded Bricks,
- Pointy Edges and Smoother Surfaces without any Irregularities,
- Bright & Uniform in color,
- Higher Compressive Strength of about 105 kg/cm2,
- Used as a Load Bearing Wall in almost all Civil Structures and,
- Water Absorption should not exceed 20% when soaked in water for 24 hours.
Class 2 Common Burnt Clay Bricks
These are also good quality Bricks but is slightly inferior to Class 1 Bricks. Class 2 bricks may be slightly overburnt or underburnt. Class 2 Bricks are the second choice of the engineers in terms of quality.
Some of the features of the Class 2 Bricks are:-
- Ground-Moulded Bricks,
- Curved Edges with Surface Irregularities,
- Bright & Uniform in Color,
- Compressive Strength less than Class 1 Bricks of about 70 kg/cm2,
- It is also used as Load Bearing Walls,
- Water Absorption should not exceed 22% when soaked in water for 24 hours.
Class 3 Common Burnt Clay Bricks
These are the lowest quality Bricks which are used in masonry. Class 3 Bricks are overburnt or underburnt bricks. Class 3 Bricks are chosen only when the budget of the construction is very low or the structure is not permanent in nature and only be used for some time.
Some of the properties of the Class 3 Bricks are:-
- Ground-Moulded Bricks,
- Broken Edges and Highly Uneven Surface,
- Dull & Non-Uniform in Color,
- Compressive Strength is lowest among the three of about 30 kg/cm2,
- Used for Temporary Structures,
- Water Absorption should not exceed 25% when soaked in water for 24 hours.
Sand Lime Bricks
Sand Lime Bricks are second in the list of different types of bricks. Sand Lime Bricks are created by combining sand, ash, and lime followed by a chemical action throughout wet mixing. The combination is then shaped under pressure forming the brick.
These bricks offer benefits over clay bricks such as:-
- Their color look is grey rather than the regular crimson color.
- Their shape is uniform and presents a smoother end that doesn’t need covering.
- These bricks provide wonderful strength as a supporting member.
Engineering Bricks are third on the list of different types of bricks. Engineering Bricks are bricks factory-made at extraordinarily high temperatures, forming a dense and powerful brick, permitting the brick to limit strength and water absorption.
Engineering Bricks provide wonderful load bearing capability damp-proof characteristics and chemical resisting properties. These bricks are employed in specific construction works and they will price higher than the regular or ordinary bricks.
Concrete Bricks are fourth in the list of different types of bricks. Concrete Bricks are made of solid concrete and are quite common among homebuilders.
Concrete Bricks are typically placed in facades, fences, and supply a superb aesthetic presence. These bricks are often factory-made to supply totally different colors and can be pigmented while its production.
Fly Ash Bricks
Fly Ash Bricks are fifth on the list of different types of bricks. Fly Ash Bricks are factory-made with clay and ash, at about 1,000 degrees Celsius.
Some studies have shown that these bricks tend to fail, once bricks get in contact with wetness and water, inflicting the bricks to expand.
Reasons for the popularity of these different types of Bricks:
There are several benefits once bricks are used as a part of the development. The subsequent list presents a number of the foremost common benefits once deploying bricks rather than alternative construction materials.
- Aesthetic – Bricks provide natural and a range of colors, as well as numerous textures.
- Strength – Bricks provide wonderful high compressive strength
- Porosity – the flexibility to unleash and absorb wetness is one in every of the foremost vital and helpful properties of bricks, control temperatures and humidness within structures.
- Fire Protection – once ready properly a brick structure will provide a fire protection high rating of six hours.
- Sound Attenuation – The brick sound insulation is generally forty-five decibels for a 4.5 inches brick thickness and 50 decibels for a nine-inch thick brick.
- Insulation – Bricks will exhibit on top of traditional thermal insulation compared to alternative building materials. Bricks will facilitate regulate and maintain constant interior temperatures of a structure as a result of their ability to soak up and slowly unleash heat.
- Wear Resistant – A brick is therefore sturdy, that its composition provides wonderful wear resistance.
- Efflorescence – Efflorescence forms on concrete structures and surfaces once soluble salts dissolved in water are deposited and accumulated on surfaces forming an apparent scum.
- Durability – Brick is extraordinarily sturdy and maybe is that the most sturdy artificial structural building material to this point.
