The types of brick masonry are as follows:
- Brickwork in mud: In this type of brickwork, mud is used to fill up the joints. The mud is prepared by intimately mixing sand and clay. The thickness of the mortar joints is 12 mm. This type of brickwork is adopted in cases of low-cost construction and the maximum height up to which a wall can be constructed in this type of brickwork is 4 m.
- Brickwork in cement mortar or lime mortar – I class: In this type of brickwork, cement or lime mortar is used. The bricks are table-moulded, are of standard shape and are burnt in kilns. The surfaces and edges of the bricks are sharp, square and straight. They comply with all the requirements of a good standard brick. The thickness of mortar joints does not exceed 10 mm.
- Brickwork in cement mortar or lime mortar – II class: The bricks to be used in this type of brickwork are moulded on ground and are burnt in kilns. The surface of these bricks is somewhat rough and their shape is slightly irregular. The bricks may have hair cracks and their edges may not be sharp and uniform. These bricks are commonly used at places where the brickwork is to be provided with a coat of plaster. The thickness of mortar joints is 12 mm.
- Brickwork in cement mortar or lime mortar – III class: This type of brickwork is the same as II class except that the bricks to be used are burnt in clamps. These bricks are not hard and they have rough surfaces with irregular and distorted edges. These bricks give a dull sound when struck together. They are used for unimportant and temporary structures and at places where rainfall is not heavy.
