Types of Bricks-Detail Classification of Bricks

Brick is a rectangular unit of regular size. They’re built of clay bricks. Typically they are used for many construction works. Where the rock is not usable, bricks are most often used as a stone substitute.

  • Manufacturing Method
  • Raw Material
  • Using Location
  • Weather-resisting Capability
  • Purpose of Using
  • Shape
  • Region

Classification of Bricks Based on Quality

Bricks are of the following types on the basis of quality:

First Class Brick: The width is the norm. These bricks have a uniform yellow or red color. It’s a well-burned, consistent texture, uniform shape. The capacity for absorption is less than 10 percent, the crushing force is 280kg / cm2 (mean) where it is 245 kg / cm2 (minimum). It has no efflorescence. If hit by another identical brick and attacked by a hammer, it produced a metallic tone. If you’re trying to do with a thumbnail, it’s hard enough to resist any fingernail expression on the brick surface. It’s free of pebbles, gravel, or organic matter. It’s usually used-

  • In a long-lasting construction, say 100 years
  • for construction exposes to a corrosive environment;
  • to make coarse concrete aggregates.

Second Class Brick: The size is standard, the yellow or red color is uniform. It’s well burned, it’s acceptable slightly over burnt. It has a regular shape; it is not appreciable for efflorescence. The ability to consume is more than 10%, but less than 15%. Crushing pressure is 175kg / cm2 (mean) with a minimum of 154 kg / cm2. If hit by another identical brick and attacked by a hammer, it produced a metallic tone. If you’re going to do a mole, it’s difficult enough to avoid some fingernail gestures on the ground of the stone. It is used to build one-story buildings, temporary shed when there is no longer than 15 years of intended durability.

Third Class Brick: It is not standard in shape and size. The color is soft and the color is light red. It’s under burned, permissible slightly over burnt. It has a strong efflorescence. The surface is not homogeneous. The potential for absorption is more than 15%, but less than 20%. The crushing force is 140kg / cm2(mean) with a minimum crushing force of 105kg / cm2. When struck by another similar brick or struck by a hammer, it emits a dull or blunt sound. As you want to do with the thumbnail, it leaves fingernail speech.

Classification of Bricks Based on Building Process

Depending on the construction process, Bricks are of the following types:

Unburnt Bricks: Half-burnt bricks. It’s yellow in color. The force is low. They are used in lime terracing as surki. Under RCC footing or basement, they are used as soiling. There should be no exposure to rainwater for such bricks.
Burnt Bricks: Burnt bricks were made in the kiln by burning them. Burnt bricks are first-class, second-class, third-class bricks.
Over Burnt or Jhama Brick: It is often referred to as the vitrified brick because it is fired at high temperatures and for a longer period than traditional bricks. As a consequence, it distorts the form.

Classification of Bricks Based on Manufacturing Method

Depending on the production method, bricks are of the following types:

Extruded Brick: produced by pressing clay and water into a steel die, with a very typical shape and size, then slicing the resultant column into smaller units with wires prior to the fire. It is used in low-budget houses. It has three to four openings that make up the brick’s thickness of up to 25 million.

Molded Brick: It is made by hand instead of being in the process in molds. Instantly, shaped bricks are accessible from 50-65 mm. In 6-8 weeks after the order, other sizes and shapes are available.

Dry pressed brick: these are the traditional brick types that are made by compressing clay into molds. In one bedding surface, it has a deep frog and a shallow frog in another.

Classification of Bricks Based on Raw Materials

Bricks are of the following types on the basis of raw materials:

Burnt Clay Brick: it is obtained by pressing the clay in molds and in kilns fried and dried. It’s the bricks that are most used. When used in construction works, this needs plastering.

Fly ash clay brick: it is produced in 1000 degrees Celsius when fly ash and clay are molded. It has a high calcium oxide volume in fly ash. That’s why they usually described themselves as self-cementing. This normally spreads as water comes into contact. It’s less porous than the bricks of clay. It has shown to be a smooth surface so that plastering is not necessary.

Concrete Brick: made of concrete. It’s the bricks that are least used. It has low strength of compression and low quality. Used above and below the damp proof course, these bricks. Because of their noise isolation and heat tolerance properties, these bricks can be used for facades, walls or inner brickworks. It’s also called the brick of the mortar. When the dye is applied during processing, it can be of different colors. It shouldn’t be used upstairs.

Sand-lime brick: under pressure, sand, fly ash and lime are mixed and molded. A chemical reaction happens during wet mixing to bind the mixtures. They are then put in the molds. The shade is grayish because it provides an artistic vision. This provides a finer finish than the clay bricks and a consistent look. As a consequence, plastering is also not necessary. As it is immensely strong, it is used as load-bearing parts.

Firebrick: It’s called refractory bricks as well. It is made from the earth that has been specially designed. It can withstand very high temperatures after burning without altering its form, volume, and power. It is used for chimney and furnaces lining where it is expected to be very high at the usual temperature.

Classification of Bricks Based on Using Location

Based on the use of location bricks, the following types are:

Facing Brick: any building’s façade material is known as facing brick. Brick faces are standard in size, are stronger than other bricks and have better durability as well. The color is red or brown shades to make the building look more aesthetic. There are many types of facing bricks that use various techniques and techniques. Facing bricks should be immune to heat, as they are more widely used on buildings ‘ exterior walls.

Backing Brick: There are no special features of these styles of bricks. They are only used for support behind the facing bricks.

Classification of Bricks Based on Weather-resisting Capability

Built on weather-resistant bricks are of the following types:

Severe Weather Grade: Such types of bricks are used in countries that are covered in snow most of the year. Such bricks are immune to freeze-thaw behavior of any kind.

Moderate Climate Grade: In tropical countries, certain forms of bricks are used. They can withstand any temperature that is high.

No Weather Grade: Such bricks were weather-resistant and used on the interior walls.

Classification of Bricks Based on Their Using

Bricks are used in many ways. Depending on their use of bricks, the following styles are used:

Typical Bricks: these are the most widely used bricks. We have no special characteristics or criteria. We have low power, low quality, high level of compression. Typically they are used on the inside walls.

Engineering Bricks: For many reasons, these bricks are known. Both have a high strength of contraction and low capacity for absorption. They’re very compact and very heavy. We have strong bearing strength, evidence of moisture, and properties of chemical resistance. They’ve got a generic red color. They are classified as category A, category B, category C. Class A is the most important, but the most common is Class B. These were mostly used for civil engineering projects such as sewers, manholes, floor services, wall stabilization, moist proof courses, etc.

Classification of Bricks Based on Shape

The following forms were focused on form bricks: Bullnose Brick: these bricks are formed into round angles. We are used to constructing a flat quoin.

Airbricks: These bricks contain air circulating holes. These are used on floors or void walls that are suspended.
Channel Bricks: They are molded into the shape of a gutter or channel. They are used in drains.

Coping Bricks: They can be half-round, chamfered, Saddleback, angled varied according to the thickness of the wall.

Cow Nose Bricks: Bricks known as Cow Nose Bricks with double bullnose.

Capping Bricks: To cover the tops of parapets and freestanding buildings, such bricks are used.

Brick Veneers: Small and used for cladding, these bricks.

Curved Sector Bricks: These are curved in shape. They are used in arcs, pavements, etc.

Hollow Bricks: These bricks are around one-third of the weight of the normal bricks. They are also called cellular or cavity bricks. Their thickness is from 20-25 mm. These bricks pave the way to quicker construction as they can be laid quickly compared to the normal bricks. They are used in partitioning.

Paving stones: hold a large amount of iron in these tiles. Steel vitrifies low-temperature tiles. We are used in walls, pavements, and garden parks. These bricks resist traffic abrasive action making the floor less slippery.

Perforated Bricks: These bricks contain cylindrical holes. They are very light in weight. Their preparation method is also easy. They consume less clay than the other bricks. They can be of different shapes like round, square, rectangular. They are used in the construction of the panels for lightweight, structures, and multistoried frame structures.

Purpose Made Bricks: These bricks are made for specific purposes. Splay and can’t make bricks for doors and jambs for windows. Engineering bricks were designed for building of civil engineering such as sewers, manholes, walls for storage. Chimneys or flares are constructed of flame bricks. Of cornices, corbels, ornamental bricks are used. Using arch bricks in arcs.

Classification of Bricks Based on Region

Cream City Bricks: Such bricks are from Milwaukee, Wisconsin, focused on the city bricks.
London Stock: In Europe, such bricks are used.
Dutch: It’s from the Netherlands.
Nanak Shahi Tiles: Indian tiles.
Greek: Used in Byzantine houses, Staffordshire Blue Brick: from Britain.
