Brick Masonry Definition
The art of laying bricks in mortar in a proper systematic manner gives homogeneous mass which can withstand forces without disintegration, called brick masonry.
The bond in brick masonry, which adheres bricks together, is produced by filling joints between bricks with suitable mortar. Special cautions shall be practised while the mortar is mixed and placed since it greatly affects the performance and durability of the masonry structure.
The coordinating dimensions are a measure of the physical space taken up by a brick together with the mortar required on one bed , one header face and one stretcher face.
The working dimensions are the sizes to which manufacturers will try to make the bricks.
# Methods of manufacture for many units and components are such that the final piece is not quite the size expected but it can fall within the defined limits.
# This can be due to the things like shrinkage, distortion when drying out, firing etc. The difference between the working and coordinating dimensions of a brick is 10mm (0.5“) and this difference is taken up with the layer of mortar into which the bricks are pressed when laying.
Types of Brick Masonry Work
1. Brick Work in Mud
The mud is used to fill up various joints brick masonry work.
The thickness of the mortar joint is 12 mm.
it is the cheapest type of brick masonry
employed for the construction of walls with a maximum height of 4 m.
2. Brick Work in Cement
This type of brick masonry is the construction by laying bricks in cement mortar rather than mud which is used in brickwork in the mud. There are three major classes of brickwork in cement which are summarized in Table.
Different classes of brickwork in cement and their descriptions
Classes of BrickWorkDescriptionsFirst Class The cement of lime mortar is used,The surface and edges of bricks are sharp,And the thickness of mortar joints doesn’t exceed 10mmSecond ClassGround moulded bricks are used, Bricks are rough and shape is slightly irregular,The thickness of the mortar joint is 12 mm.Third Class Bricks are not hard, rough surface with distorted shape, Used for temporary structures,Used in places where rainfall is not heavy.
