Bricks

Types of Bricks

Based on material such as clay, concrete, lime, fly ash, an, etc different types of bricks are used and for different constructions work field identification of bricks for their properties, suitability, and use is important. Manufactured from clay brick is an important construction material that is available in a rectangular shape.

 

Bricks are to be categorized into many types which depend on their making processes,

quality and the raw material is going to use and also their using purpose.

But mainly we can categorize the brick into six main types and then subtypes.

1. Burnt Clay Bricks

2. Concrete Bricks

3. Fly Ash Bricks

4. Fire Bricks

5. Sand Lime Bricks

6. Sun-Dried Bricks

BURNT BRICKS

The classic form of the bricks is burnt clay bricks. These types of bricks are created by pressing the wet clay into the molds then drying and firing in the kilns. This material is the oldest building material; these bricks are the solid blocks of hard clay & reddish in color. These bricks have the best quality and good strength but costly.

Burnt clay bricks are also classified into four types;

FIRST-CLASS BRICKS

They are good quality bricks as compared to other and these bricks contain standard shape, smooth surface, and sharp edges. These are created by table molding and burnt in large kilns.

1. Type 1. First Class Brick 2. Size 2. 19 x 9 x 9 cm 3. Crushing Strength 3. 105 kg/cm2 4. Edges 4. Sharp and square. 5. Color 5. Uniform red or brown. 6.Shape 6. Standard and uniform (rectangular) 7.Water Absorbing 7. 15%  to 20 % of its self-weight when submerged in water for 24 hours. 8.Surface 8. Smooth and straight 9. Use of this Brick 9. Superior work,1 class construction   SECOND CLASS BRICKS: They are moderate qualities that are molded by the process of ground molding. They do not have a smooth surface and sharp edges because of ground molding but these bricks also result in strength and durability.  THIRD CLASS BRICKS: They are poor quality bricks used for temporary structure and not suitable for rainy areas. These bricks are burnt in clamps and surface of these type of bricks have unfair edges and are rough.                       Brick                                     Properties 1. Type 1.

FOURTH CLASS BRICKS

They are very poor quality bricks and not used in the structure, in aggregates they are crushed and used .

These bricks are solid blocks and have good quality & strength, so these are used in the foundations, columns & masonry walls.

FIRE BRICKS

The fire bricks are made up of specially formulated earth with high aluminum content. These bricks can stand with high temperatures without changing their shape, size, and strength after burning.

Uses:

Fire bricks are mostly used in chimneys, fences, pizza ovens, and outdoor barbecues.

Hollow Bricks:

Hollow bricks are lightweight and insulating bricks, which are used for reducing the weight and cost of construction, as well as improving the energy efficiency and comfort of buildings. Hollow bricks have a cavity or core, which can be filled with insulation material or reinforced concrete.

 Concrete Bricks:

Concrete bricks are made from cement, sand, and aggregate. They are denser and stronger than clay bricks and are commonly used for construction in areas prone to extreme weather conditions. Concrete bricks are also less expensive than clay bricks, making them a popular choice for builders on a budget.

Sand Lime Bricks:

Sand lime bricks are made from sand, lime, and fly ash or cement. They are popular for their durability, strength, and resistance to moisture. Sand lime bricks are also environmentally friendly and can be recycled.

 Clay Bricks:

Common Bricks

Common bricks are the most basic type of bricks, which are usually red or brown in color, and have a rough surface texture. Common bricks are made of clay or shale, and are typically used for building walls, foundations, and chimneys.

 Facing Bricks:

Facing bricks are also known as “cladding” or “veneer” bricks, and are used for the visible surfaces of buildings, such as facades, entrances, and accent walls. Facing bricks are available in various colors, textures, and shapes, and can enhance the aesthetic appeal of a building.

Engineering Bricks:

Engineering bricks are strong and durable bricks, which are used for heavy-duty applications, such as in structural walls, sewers, and bridges. Engineering bricks have a dense composition, and can resist high pressure, frost, and erosion.
