• They can be used to create a sense of solidity and strength in the design.

Explanation:

Flemish Bond:

• In every course headers and stretchers bond are placed alternatively.
• A queen closer is put next to the quoin header.
• Every header is centrally supported over a stretcher below it.
• In thin board short continuous vertical joints are formed.
• Brickbats are to be used in the uneven multiple of half brick.
• It is the weakest bond in a brick masonry wall.

A. Single Flemish Bond

• The facing elevation is a Flemish bond but the backing and hearting are of English bond.

B. Double Flemish Bond

• The headers and stretchers are placed alternatively in facing as well as backing.

Uses:

• For structural work or load-bearing walls
• Having a pleasing appearance.

Additional InformationEnglish Bond:

• Alternate courses consists of headers and stretchers.
• Queen closer put next to the quoin header to get lap.
• Each alternate headers centrally supported on stretchers.
• Continuous vertical joints are not formed excepted stopped ends.
• Header course should never start with a queen closer.
• Queen closers are not required in stretcher course.
• Minimum lap should be ¼ th brick. 1,2,3...thick wall same look on both faces Multiple of half thick wall not in same look in facing and backing.

Explanation:

Plugged joint

• This is used for coping cornice etc.

Additional Information

Cramped joint:

• It prevent the tendency of stone joint to pull apart. This joint is used instead of dowel joint.

Tongued and grooved joint or joggled joint:

• Joint require more labour make expensive. 
• It is used only in some portions of ashlar masonry.

Explanation:

The part marked "X" represents the coping.

Coping:

• Trowel: Used for spreading and shaping mortar, not suitable for cutting bricks.

• Brick hammer: Used for chipping or cutting bricks, but less precise for dressing surfaces compared to a scutch.

Explanation:

The name of the part marked as 'x' is mesh reinforcement.

Explanation:

Diagonal bond:

• Bricks are laid longitudinally, useful for 2-4 brick thick.

Additional InformationGarden wall (English) bond:

• One header course is provided to two or five stretcher courses.
• Quoin headers are placed in alternate bond course and queen closer is placed next to the quoin header in header course to develop lap.

Monk bond:

• A header is placed centrally over each middle stretcher.
• Each course contain one header to two stretchers
• The header rest on the joint between two headers.
• A \(3\over4\)th bat is placed next to the quoin header.

Explanation:

Cornice brick marked as X in brickwork.

Cornice Brick

• A cornice brick is a specialized type of brick used in construction, primarily for decorative and architectural purposes.
