Brick Types and It's Classification

Brick Types and It’s Classification

As a part of our civil engineering blog series, here we are going to discuss regarding the various types of bricks used during construction.

Before beginning with the same, here is a useful bit of advice for you. For all those civil engineers who want to learn Revit, can join a Revit training program. It can be your add-on skill.

Now, we will focus our attention on the different types of bricks.

Bricks are broadly classified under these two categories:


  1. Burnt bricks

  2. Sun-dried or Unburnt bricks

Unburnt bricks:

Unburnt blocks or sun-dried blocks are the sorts which are dried with the assistance of heat got from the sun after the moulding process. These bricks can be utilized as a part of the construction of temporary and shabby structures. Such blocks ought not be utilized at places exposed to substantial downpours.

Burnt bricks:

Burnt bricks are produced by burning the block-mould in a furnace inside the industrial facility. These are the most regularly utilized blocks for construction activities. They can be additionally grouped into following four classes:

  • First class:

These blocks happen to be table-moulded and of standard shape and they are baked in kilns. The edges and surfaces of these bricks are square, sharp, smooth and straight. They abide to every one of the characteristics of good bricks. These bricks are utilized for superior quality work that is of a perpetual nature.

  • Second class:

These blocks are ground-moulded and they are heated in kilns. The surface of these bricks is fairly rough and shape is additionally marginally irregular. These bricks might possess hair cracks and their edges might not be sharp and uniform. These type of blocks are usually utilized at places where brickwork is to be furnished with a layer of plaster.

  • Third class:

These bricks are ground-moulded and they are burnt in furnaces. These bricks are softer and they have rough surfaces with unpredictable and misshaped edges. These bricks provide dull sound when struck together. They are utilized for insignificant and impermanent structures and at locations where rainfall is not substantial.

  • Fourth class:

These are over-scorched kind of bricks with a random shape and dark colour. These blocks are utilized as total for concrete in foundations, streets, floors and so on in view of the way that the over-burnt bricks have a compact structure and subsequently they are at times stronger than even the bricks of the first class.

Shape based classification of bricks:

The common bricks are rectangular solids. Be that as it may, here and there the blocks are given diverse shapes to make them useful for specific sort of construction activities. Here we have listed down distinctive sorts of bricks present with different shapes:

  • Channel bricks:

These sorts of bricks are formed to the shape of a drain or a channel and they are frequently glazed. These blocks are utilized to work as drains.

  • Paving bricks:

These blocks are produced using clay containing a higher level of iron. The overabundance iron vitrifies the bricks at a lower temperature. Such blocks oppose better the abrasive activity of traffic. The paving blocks might be plain or checkered. These bricks are broadly utilized for garden walks, stable floors, roadside pavements and so on. These sorts of bricks likewise render the floor less slippery.

  • Bullnose brick:

A brick formed with a rounded angle is named as a bull-nose. This kind of brick is utilized for a rounded quoin. An association which is formed when a walls takes a turn is called as a quoin. The focal point of the curved position is arranged on the long core line of brick.

Other types include hollow bricks, cow-nose bricks, perforated bricks, purpose-made bricks etc…

Thus, we acquainted you with the varied types of bricks.
