Brick MasonryBrick Masonry may be defined as the laying of bricks in a systematic pattern , bonded with mortar to form a well united mass.

Advantages of MasonryBricks are light in weight and convenient in sizeThey can be easily handled by mason by one

hand They can be manufactured at all the sites and are

easily availableDue to light weight properly, they do not require

any lifting appliancesAs they are uniform in size, they can be used in

definite set pattern termed as bondsLike stone block they do not require any dressing

Principle In Brick Masonry Construction

• In brick masonry work , the bricks used should be sound , hard , well burnt with uniform size , shape and color.

• The bricks should be free from all types of defects like holes , cracks , flaws , air bubbles , stone lumps , lime lumps , over burnt etc .

• To ensure proper bond between old and new brick work, the walls should be stopped with the toothed end

• When the mortar is in green stage, the joints should be properly flushed and filled with mortar so that no cavity is left in between

Technical Terms In Brick Masonry

• Brick: A brick is a block or a single unit of a ceramic material used in masonry construction

• Header: The face of brick showing breadth and height of brick is termed as header

• Stretcher: The face of brick showing length and height of brick is termed as stretcher

• Frog: The depression provided on the top face of the brick during its manufacturing is termed as frog

• Course: Each horizontal layer of bricks, laid in mortar in brick masonry construction is known as course

• Bond; The process of arranging bricks with mortar to tie them together in a mass of brick work is termed as bonding

The Procedure for Building Brick Walls

The procedure for building brick walls. This example is a single wythe of running bond.

（ A） The construction of a brick wall begins with the laying of leads. The leads establish the wall planes and course heights

（ B） The bricks between the leads are laid to a line, a heavy string stretched taut between line blocks at each lead

（ C）When the entire wall is laid to the level of the top of the leads, a second set of leads is laid, and the entire process is repeated as many times as necessary

Bonds In Brick Masonry

• Bonding is a process of arranging bricks with cement , sand , mortar to tie them together in a solid mass of brick work. the bricks are arranged in courses and bonded together ,to act as a single unit for carrying load.

Different Types of Bond

Method of bonding New Brick work with oldWhen it is desired to increase the length of the wall under construction at a future date, the wall should be stopped with a toothed end. It is necessary to ensure continuous bonding between the old and the new brick.

Raking Back: In rising the corner, the courses end in a series of steps in order that the men on the wall may place the courses to it in the easiest manner. In simple words, each course on the wall will be shorter than the course below it.

Block Bonding: It is used in situations where a new wall is to be tied into an existing wall, but where appearance is of no importance. This method is trying in a wall is similar to toothing with the exception that three to five courses are cut out to form the tie.

Expansion and Contraction jointExpansion joints are provided to allow free

expansions of the structure due to increase in temperature. If these joints are not provided at

suitable intervals, then the structure shall subjected to internal compressive stresses. These

stresses can cause the failure of structure.

Reinforced Masonry Walls

It may be either a solid masonry wall or a masonry cavity wall. Reinforced Masonry Walls Load bearing masonry walls may be built with or without reinforcing. Unreinforced walls cannot carry such high stresses as reinforced walls and are unsuitable for use in regions with high seismic risk, but such walls have been used in the United States to support buildings as tall as 16 stories.
